In the 1930s journalists from publications like the New York Times and Time magazine would regularly visit Nikola Tesla at his home on the 20th floor of the Hotel Governor Clinton in Manhattan. There the elderly Tesla would regale them with stories of his early days as an inventor and often opined about what was in store for the future.
Last year we looked at Tesla’s prediction that eugenics and the forced sterilization of criminals and other supposed undesirables would somehow purify the human race by the year 2100. Today we have more from that particular article which appeared in the February 9, 1935, issue of Liberty magazine. The article is unique because it wasn’t conducted as a simple interview like so many of Tesla’s other media appearances from this time, but rather is credited as “by Nikola Tesla, as told to George Sylvester Viereck.”
It’s not clear where this particular article was written, but Tesla’s friendly relationship with Viereck leads me to believe it may not have been at his Manhattan hotel home. Interviews with Tesla at this time would usually occur at the Hotel, but Tesla would sometimes dine with Viereck and his family at Viereck’s home on Riverside Drive, meaning that it’s possible they could have written it there.
Viereck attached himself to many important people of his time, conducting interviews with such notable figures as Albert Einstein, Teddy Roosevelt and even Adolf Hitler. As a German-American living in New York, Viereck was a rather notorious propagandist for the Nazi regime and was tried and imprisoned in 1942 for failing to register with the U.S. government as such. He was released from prison in 1947, a few years after Tesla’s death in 1943. It’s not clear if they had remained friends after the government started to become concerned about Viereck’s activities in the late 1930s and early 1940s.
Tesla had interesting theories on religion, science and the nature of humanity which we’ll look at in a future post, but for the time being I’ve pulled some of the more interesting (and often accurate) predictions Tesla had for the future of the world.
Creation of the EPA
The creation of the U.S. Environmental Protection Agency (EPA) was still 35 years away, but Tesla predicted a similar agency’s creation within a hundred years.
Hygiene, physical culture will be recognized branches of education and government. The Secretary of Hygiene or Physical Culture will be far more important in the cabinet of the President of the United States who holds office in the year 2035 than the Secretary of War. The pollution of our beaches such as exists today around New York City will seem as unthinkable to our children and grandchildren as life without plumbing seems to us. Our water supply will be far more carefully supervised, and only a lunatic will drink unsterilized water.
Education, War and the Newspapers of Tomorrow
Tesla imagined a world where new scientific discoveries, rather than war, would become a priority for humanity.
Today the most civilized countries of the world spend a maximum of their income on war and a minimum on education. The twenty-first century will reverse this order. It will be more glorious to fight against ignorance than to die on the field of battle. The discovery of a new scientific truth will be more important than the squabbles of diplomats. Even the newspapers of our own day are beginning to treat scientific discoveries and the creation of fresh philosophical concepts as news. The newspapers of the twenty-first century will give a mere ” stick ” in the back pages to accounts of crime or political controversies, but will headline on the front pages the proclamation of a new scientific hypothesis.
Health and Diet
Toward the end of Tesla’s life he had developed strange theories about the optimal human diet. He dined on little more than milk and honey in his final days, believing that this was the purest form of food. Tesla lost an enormous amount of weight and was looking quite ghastly by the early 1940s. This meager diet and his gaunt appearance contributed to the common misconception that he was penniless at the end of his life.
More people die or grow sick from polluted water than from coffee, tea, tobacco, and other stimulants. I myself eschew all stimulants. I also practically abstain from meat. I am convinced that within a century coffee, tea, and tobacco will be no longer in vogue. Alcohol, however, will still be used. It is not a stimulant but a veritable elixir of life. The abolition of stimulants will not come about forcibly. It will simply be no longer fashionable to poison the system with harmful ingredients. Bernarr Macfadden has shown how it is possible to provide palatable food based upon natural products such as milk, honey, and wheat. I believe that the food which is served today in his penny restaurants will be the basis of epicurean meals in the smartest banquet halls of the twenty-first century.
There will be enough wheat and wheat products to feed the entire world, including the teeming millions of China and India, now chronically on the verge of starvation. The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb. I developed a process for this purpose in 1900. It was perfected fourteen years later under the stress of war by German chemists.
Tesla’s work in robotics began in the late 1890s when he patented his remote-controlled boat, an invention that absolutely stunned onlookers at the 1898 Electrical Exhibition at Madison Square Garden.
At present we suffer from the derangement of our civilization because we have not yet completely adjusted ourselves to the machine age. The solution of our problems does not lie in destroying but in mastering the machine.
Innumerable activities still performed by human hands today will be performed by automatons. At this very moment scientists working in the laboratories of American universities are attempting to create what has been described as a ” thinking machine.” I anticipated this development.
I actually constructed ” robots.” Today the robot is an accepted fact, but the principle has not been pushed far enough. In the twenty-first century the robot will take the place which slave labor occupied in ancient civilization. There is no reason at all why most of this should not come to pass in less than a century, freeing mankind to pursue its higher aspirations.
Cheap Energy and the Management of Natural Resources
Long before the next century dawns, systematic reforestation and the scientific management of natural resources will have made an end of all devastating droughts, forest fires, and floods. The universal utilization of water power and its long-distance transmission will supply every household with cheap power and will dispense with the necessity of burning fuel. The struggle for existence being lessened, there should be development along ideal rather than material lines.
Tesla was a visionary whose many contributions to the world are being celebrated today more than ever. And while his idea of the perfect diet may have been a bit strange, he clearly understood many of the things that 21st century Americans would value (like clean air, clean food, and our “thinking machines”) as we stumble into the future.

This is the eleventh in a 24-part series looking at every episode of “The Jetsons” TV show from the original 1962-63 season.
The 11th episode of The Jetsons opens with a police officer pulling over Montague Jetson — George’s grandfather and a man whose abundant energy and enthusiasm for life dominate the episode. The cop observes that Grandpa Jetson is, “110… and still acting like a man of 75.” With that, we learn that the promises of the 20th century were true: not only will people of the future live longer, they’ll be much happier and healthier. Titled, “A Visit From Grandpa,” the episode first aired on December 2, 1962 and looked at everything from future fashions (when Judy and Jane come home with an assortment of new hats) to sports of the future (when Grandpa Jetson plays with and bests every member of the Jetson family at their favorite sport).
In “The Jetsons” everything naturally has a Space Age twist — even the fashion. When Judy and Jane come home from shopping they model their new hats for George which include names like “Moonscape,” the “Cosmonautris” and the “Nuclear Look.” All of these looks appeal to the googie-tastic flare that we’ve come to associate with mid-century futurism and more often than not, what people of the 21st century call the “Jetsons look.” But these far out styles have roots that extend beyond the 1939 New York World’s Fair. The dress at right was featured in the February 1, 1939 issue of Vogue magazine and was designed by Henry Dreyfuss for the woman of the year 2000.
Retailers of the 1930s would sometimes put on futuristic fashion shows but the trend really took off in the 1950s and 1960s, with designers who were inspired by the techno-utopian ideas of the era. In 1957, Marshall Field’s in Chicago had a two week exposition of American living in the year 2000. The store showcased the futuristic works of 17 apparel and accessory designers, giving customers a peek at the supposed futuristic fashions to come. From the May 15, 1957, issue of the Chicago Daily Tribune:
Most of the designers represented agreed that the fashionable woman of the future will be wired for sound, with sending and receiving equipment built into their costume. Fabrics will be treated to be warm in winter and cool in summer. Some will screen the sun to allow tanning without burning while others, used in bathing suits, will make them unsinkable.
The article went on to explain that fashion of the future would require plenty of pockets for all the high-tech gadgets and meal pills we’d all be using.
A futuristic lounging robe by Dorian, for example is equipped with 40 pockets containing food pills, electrical outlets for instant permanents, and communications systems with robot controls to keep the housewife in touch with the laundry, the nursery, and the kitchen.
And what about the Space Age wedding? We’ve looked at late-1950s predictions for honeymoons on the moon. According to fashion designer Zagri, the wedding itself will take place on Venus:
The chic place for weddings of the future will be the planet Venus, according to Chicago designer Zagri. Her design for a bridal costume is a convertible two-piece ensemble of luxurious gold lame. The voluminous skirt and train comes off to reveal a coverall suitable for a space ship honeymoon. A huge plastic bubble equipped with radar is the bride’s headdress.
The rocking chair is a symbol of a slower life — the natural desire to take it easy as one becomes older and less agile. Grandpa’s futuristic rocking chair (or at least the one that George and Elroy are working on for him) is another example of Jetsons technology that doesn’t operate quite as it was intended. Silly jokes like George wobbling around on an out-of-control rocking chair are certainly par for the course during any cartoon, but in the Jetson household they also speak to a kind of conservatism that runs throughout the series. Using sight gags, the show will often argue that messing with symbols of tradition (like the rocking chair) will have unpleasant consequences. And tradition aside, there’s no way Grandpa Jetson needs a rocking chair, since in the future even a man of 110 years old will be as happy and healthy as a person half his age.
Predictions of increased longevity became extremely popular mid-century, but they date back much further. The January 2, 1926 Charleston Gazette included a short article about predictions for a future when humans might live to see 200 years old:
A serious scientist has glad news for all those that want to stick to this world, in spite of its troubles and worries. In the year 2000, says he, the average life will be 100 years, and many will live to be 200 years old.
That will interest birth control advocates, for something in the way of birth control would seem to be necessary in 2000 A.D.
A man and woman 200 years old might easily have thousands of descendants. Providence, however, doesn’t let the trees grow into the heavens.
A quarter of a century later the Associated Press would look at life expectancy and health into the year 2000, with a short piece by the AP’s medical editor in 1950:
Medicine by the year 2000 will have advanced the length of life of women to an expectation of nearly 80 and of men to over 75.
The record will be better if the cause and cure of cancer is discovered. Cancer is a form of growth. It is part of metabolism. Concerning growth, nothing is now known. Metabolism is not such a complete mystery, but is complex. Most of the chronic diseases, except infections caused by germs and viruses, are based on metabolism gone wrong.
Growth, metabolism and cancer studies will make the first break into clearing another mystery, the causes of aging. After that is known it will be possible to control aging so that elderly persons will be healthy to nearly the end of their lives.
Hope is very good for restricting cancer’s attack before 50 more years, but not for eradicating it. For it now appears that cancer is not a single disease, but takes many forms.
The prevention of baldness depends on studies of growth, aging and death more than on any other now known factor.
Public health will improve, especially the knowledge of how air carries infections, like the common cold, from person to person. Before 2000, the air probably will be made as safe from disease-spreading as water and food were during the first half of this century.
Surgery, which has been the fastest-moving side of medical science, will by 2000, be able to repair bodies damaged by disease, by accidents or by heredity so that the “lame and the halt” will nearly disappear. Polio probably will be stopped well before 2000.
Since the episode revolves around the fact that the elderly will be able to stay active well into old age, we see Grandpa Jetson participate in physical activity with every member of the family. Grandpa shows that he can keep up with Judy’s dance moves, he can both pitch and catch against Elroy in spaceball (which bares a striking resemblance to baseball), he can best George in bowling, he can sky-ski with Jane, and he can play catch with Astro.
The Jetsons, as we’ve seen, most often want to present viewers with something relatable to a mid-century audience. With this in mind we understand why our family of the year 2062 all participate in sports that are familiar to the people of 1962 rather than completely fabricating a new sport. Just add “space” “sky” or “nuclear” to anything and voila: it’s been futured. Or more appropriately from the vantage point of the 21st century: it’s been Jetsoned.

The February 26, 1977 edition of the Herald-Star in Steubenville, Ohio published dozens of predictions for the year 2000 made by the people of Steubenville, a working class town in eastern Ohio (and the birthplace of Dean Martin). Some of these letters came from local middle school kids 10-12 years old and they provide a fascinating snapshot of the era; unique in their ability to reflect the pessimism stirred by a down economy and shaken faith in government in a post-Watergate, post-Vietnam War era, while also laying bare the irrational optimism of youth.
Many of the predictions are clearly influenced by the energy crisis, with many kids predicting there will be tough times ahead without access to cheap energy. However, there’s also optimism about space exploration and more than one reference to women as astronauts. Even though Valentina Tereshkova became the first woman in space in 1963, the first American woman (Sally Ride, who died this past summer) wouldn’t become an astronaut until 1983 — a full six years after these kids were making their predictions.
Interestingly, for being middle schoolers these kids sure seem concerned about high taxes. All of these kids are now between 45 and 48 years old and if you happen to be one of them, I’d love to hear from you. How do you feel reading your predictions from the vantage point of “the future”? How do you feel about the years to come?
Some of the letters from the February 26, 1977 Herald-Star appear below:
New Great Depression
I think that by the year 2000 we will be in a great depression. People are saying that we are running out of fuel. People will be using machines to do everything. And machines run on fuel. If we run out of fuel we won’t be able to run the machines and people will be out of jobs. So we can save fuel. Everybody should try to save by turning their heat to 68 degrees.
Debbie Six, 12 (Harding School)
We’ll Find More Oil
My view of the future is that we will find more gas and oil. No one will be poor and we all will live in peace! Also in the future, I think they will find some mechanical device that could make kitchens, dining rooms and etc. You’d just push a button and WHAM!! An instant living room or WHAM!! an instant milkshake. And that’s my view of the future!
Emma Conforti, Age 11 (Harding School)
Robot Maids, Robot Teachers
In the year 2000, we will have all round buildings. We will have a robot teacher, a robot maid, and all workers will be robots, too. We will have a pocket computer that has everything you can name. We will even be able to push a button to get anything you want!
Marty Bohen, Age 10 (Harding School)
Electric Cars and Ladies on the Moon
The year 2000 might have everybody walking instead of riding in their cars because there might be a gas shortage by then, and the cars give out a lot of pollution. Or there might even be electric cars instead of gas cars. The year 2000 may send ladies to the moon to explore and look and see if there are people living on the moon. And when you work you will push buttons and robots will come out and do the work for you. And there will be lower prices and taxes, I hope.
Tim Villies, 10 (Harding School)
Cures For Every Sickness
In 2000 I will marry a doctor and maybe have kids. I would like my husband to be a doctor because he would be helping people and would still want to be close to my family. As for a job for me I would help the crippled boys and girls. I would still like to have my same friends. And the most important thing for there to be is no wars and killings. I hope they could find cures for every sickness. And everybody will care for each other.
Monica Katsaros, Age 10 (Harding School)
The Last Five Years Haven’t Been So Good
I think 2000 will be a good year. I hope so because the last five years haven’t been so good with people dying and getting shot and murdered. I will be a grown man by then and will be married. I’ll probably have kids. I hope it will be a good America.
Michael Beal, Age 10 (Harding School)
In the year 2000, I think there won’t be any crimes of any kind. Shorter school days and lower taxes. I hope there will be lower taxes and no crimes because I’ll be 33 years old and I am sick of crimes and high taxes. I hope woman can be astronauts. I also hope there won’t be any pollution. And I also hope there will be town in space, where people live in space capsules.
Lora Ziarko, Age 10 (Harding School)
Cars That Float On Air
I think the future will be better than it is now. The pollution problem will be solved and there will be cars that float on air. I will be 34 in the year 2000. I will have a good job designing modern houses with push-button controls for everything to make it easier on everyone.
You could push a button and a bed would unfold from the wall. Everything would run on solar energy so you wouldn’t have to worry about the fuel shortage. You wouldn’t have to go to school. It would be on TV and living would be much easier for everyone.
John Vecchione, Age 11 (Harding School)
Young People Unemployed
I think by the year 2000 we will be riding bikes or driving solar-energized cars. By then more younger people will be unemployed. The price of gas will go up and so will the price of coal, silver, gold and oil.
Pietro Sincropi, 10 (Harding School)
Living on Mars
I think it is going to be an all-new world. People are going to be able to live on the moon and on Mars. Man is going to have computers to do the work for him. It is going to be a computer run world.
Tracy McCoy, Age 12 (Harding School)
Most of the World Will Be The United States of America
In the year 2000 I will be 34 years old. And actually I don’t think kids will have to go to school, because I believe that families will have computers to educate students. That’s all for education. I also believe that most of the world will all be the United States of America. I also believe that business and industry will be up 75 per cent. And as for culture, the Model T will be an old artifact. And, if you have children or grandchildren, they’ll all be more interested in culture than ever.
Mike Metzger, Age 10 3/4 (Harding School)
I Hope By Then Things Will Get Better
I think that everything by the year 2000 will be different. I hope the violence will all be stopped. I hope that the computers don’t take over people’s jobs. I hope by then things will get better.

According to Athelstan Spilhaus, writing the comic strip “Our New Age” was his way of slipping a little subliminal education into the Sunday funnies. Each week the strip took a different topic—such as ocean currents or heredity or the moons of Mars—and explained in a very straightforward way just what made that area of scientific discovery so interesting. Sometimes, he would dabble in futurism, looking at automated hospitals or the robot teachers of tomorrow—but the December 26, 1965 edition of the strip stands out as its most forward-looking. Spilhaus clearly had some fun writing about these mid-’60s predictions that included everything from citizens voting on specific laws by telephone to the dapper-looking kangaroo servants of the future.
The prediction for 1976? That human space flight (the moon landing was still 4 years away, mind you) would become so common place that rescue missions for astronauts stranded in orbit may be necessary from time to time.
According to the above panel, the world of 1986 would see synthetic food, no doubt similar to the meal in a pill or some other factory-made contrivance. And, by the year 2006, the strip argues, people will see the rise of a form of direct democracy enabled by advancements in telecommunications. (A similar version of direct voting by citizens was predicted in a 1981 children’s book called World of Tomorrow: School, Work and Play.)
Today, the more techno-utopian among us hope that one day we may be able to upload our entire brains into computers. But this 1965 vision of the year 2016 would be happy with a simple direct-link. Basement biohackers are currently experimenting with different ways to alter the human body, but we’re still quite a ways from the technological singularity.
Time and again we’ve seen predictions of robot servants, like the Jetsons‘ Rosey. But every once and a while we come across more blood and bone visions of our futuristic servants. For instance, in 1967 nuclear chemist Glenn T. Seaborg predicted that, by the year 2020, we’d all be driven around by super-intelligent ape chauffeurs.
In that same vein, the last panel of this comic strip gave kids of the 1960s hope for a kangaroo butler in their future. Now, the kangaroo’s method of hopping may make balancing a tray such as that impractical, but you can’t deny that he certainly pulls off that bow-tie.

The October 1944 issue of Science and Mechanics looked at what technological advancements Americans might expect after WWII with an article titled, “Big Things Ahead — But Keep Your Shirt On,” by John Silence.
What makes this article so fascinating is that it looks at the advances of the future with optimism, but tempers that rosey outlook with realistic predictions. There were a number of stories in the early 1940s offering American readers a vision of the future after the war, but this is one of the few that asks people to keep their expectations in check. The article opens with the common assumptions of the day about the futuristic post-war world Americans would be living in:
Many of us have the idea that when Johnny comes marching home to his post-war world, he won’t know the old place. He’ll zing in on some contraption just short of the fourth dimension, and before he can zip himself out of his uniform and into his civvies, the walls of his pre-fabricated house will glow with electronic heat or his brow will be cooled by costless air conditioning.
The freezer in the basement will yield a perfect sirloin steak that the radio oven will broil to his favorite turn in something under 10 seconds, and while they’re bringing it in on an electric-plastic tray that keeps it hot, the dehydrated mush is being turned back into honest potatoes. And so on.
The piece then warns that you shouldn’t get your hopes up too much. It’s really one of the most sober and subdued pieces of futurism I’ve read from the last 100 years, but it gives us a fascinating look at the thinking of the time:
But don’t expect too much. And don’t expect it all at once. For many reasons, we aren’t going to turn things upside down as soon as the last shot is fired in this conflict. The people who risk their money to provide the things you buy are going to hold back to find out if you’ll take it before they plunge too deep. And all their research may be overruled on appeal.
The article says that frozen food will be the food of the future, with refrigerated trucks making regular deliveries to homes that have large freezers in their basements:
Foods—Quick freezing has pretty much passed its tests. People will buy frozen foods, and they’ll also store their own produce in rented lockers or home freezers. Which way will the cat jump? There are some folks who think the frozen food industry may eventually—get that “eventually”—work around to a system whereby you’ll keep a large frozen food locker in your basement, and make your purchases from a refrigerated delivery truck that comes around every week or so.
The article has a little fun with the idea that huge windows would be in fashion after the war, but may not be terribly practical:
Housing—It isn’t cricket to throw cold water on your ideas about letting the sun heat your home through huge plate glass windows. But please bear in mind that Mama is going to have something to say, too, and if your big windows open up the innards of your house to prying eyes 20 feet across the lot line, you may come in some fine sunny day to find the drapes drawn and the furnace pumping away.
The piece pointed out that advances in medicine would revolutionize our world, though they may not get as much attention as advances in consumer goods.
Medicine—Among all the scientific advances being made during the war, medicine and surgical methods probably will draw the least public attention, but they probably will influence your post-war life more than any other. The mold drugs give one example. Penicillin, the wonder mold derivative, already has been released, in controlled amounts, to the public.
And speaking of consumer goods, the writer acknowledges the sales pitches that were so common from peddlers of the era:
Household appliances—When the post-war planner regales you with stories about automatic washers, ironers, dish washers, garbage disposal machines, tell him to smile when he says it. You had all those things before the war, and you’ll have them again, if you’ve got what it takes—and that’s money and time to wait for more to be made.
In describing the community of tomorrow the writer makes reference to an illustration from 1895 that humorously imagined the future. The writer predicts that any changes in the community of the future really can’t be foreseen, but will likely be basic and simple.
Community Planning—A half century ago an artist did the same kind of thinking about his future that many people today are doing about ours. He came up with an idea of what the skyscraper of the future—say about now—would look like. [...] He reserved a large section of the building for a hay and feed store! He reckoned without the automobile, which was to change the whole complexion of things within 10 years and make his drawing appear fantastic. We can still count on a wonderful new world opening up before our eyes, but the man who promises you a preview of it just can’t deliver. The furbelows and fripperies that ease the life of the next generation are going to be governed largely on basic, probably simple, changes in our way of living that perhaps no one today can see.
The writer expects that tomorrow’s cars will be leaner and more efficient with engineers figuring out how to produce more with less. Curiously, he also holds out hope for a steam-powered car.
Motoring—On the basis of our wartime scare on the scarcity of petroleum products, it would almost seem safe to predict that the automobile of the future will be lighter and more efficient, getting as much as 50 or 100 miles to a gallon of the best grades of gasoline. The engineers probably will add strength while casting off weight. But who is to say that we won’t be extracting a fuel like gasoline from other products that will permit us to continue running our two-ton heaps because, if for no other reason, we like ‘em? And besides, although steam was tried and discarded once as an automobile power source, such improvements have been made in boilers and heating plants, as well as in the engines themselves, it is entirely possible someone will market, some day, a steam automobile that will go when you press your foot on the accelerator first thing in the morning. There are startling things afoot in both power and fuel developments. But they will be announced slowly and carefully. Watch also transmissions, especially in the hydraulics and electrical fields.
The writer predicts quite accurately that after the war the American public will see FM radio and television.
Radio—What can we look for may be these things:
- At first, a set just like we’ve always had, because the manufacturer will have all he can do at first just to fill the demand.
- Then, likely, FM, because it was about ready for the public when the conflict started, and the transmitters are already reaching a good portion of listeners.
- Television—later. Because of the short carrying qualities of television waves, it will come out first in heavily populated centers where there are transmitters.
The machine tools of war are seen as the most obvious advances that would be quickly converted for peacetime purposes.
Machine Tools—It’s most likely that the greatest advances are being made now, and not waiting until after victory is won. The stress and pressure for speedy production is bringing about advancement in the field of specialized machine tools that make our country the undisputed leader of the world’s industrial production. It may be this will prove our real victory in the war.
Futurists of the 1940s had a particular interest in helicopters, predicting that there would be a flying machine in every garage after the war. But the writer of this article is quick to explain the hurdles to such a helicopter-centric society.
Aircraft—A helicopter in your back yard? The picture is bright. You go out behind the apple tree, give the rotors a whirl, and whizz!—you’re on the office roof. At the end of the day, whizz!—and you’re back in Suburbia, tending your delphiniums. Beautiful picture, isn’t it? But you’ll probably have to keep your machine in perfect condition, to be passed on by some safety agency, and it won’t be the perfunctory windshield wiper and horn test, either. The neighbors may not care if you crack your own skull, but they won’t want you doing it on their sun porches. So for some years after the war is over, the first helicopters, and other airplanes for that matter, will be flown by people who can scrape together enough money to insure: (1) a machine in perfect condition; (2) maintenance that will keep it that way; (3) expert training in the operation of the machine. The designers say helicopters are harder to fly than airplanes.
