People in the 1900s made some wild predictions about the future—but they weren't all wrong

11 fantastical predictions too outlandish to be true. And 3 that totally came true.

future predictions

French drawing series on scientific progress about the year 2000

Do you ever wonder what the future used to look like?

I mean back in the day, before we all walked around with glass bricks in our pockets that contained every piece of information that's ever been available and allowed us to connect with anyone anywhere in the world in real time. What did people from more than 100 years ago think our future might look like?

That was the question posed to French commercial artist Jean-Marc Côté in 1899. Côté and his team were commissioned to create a series of cards to commemorate the 1900 world's fair, "Exposition Universelle," in Paris, featuring images of how the world might look in the then-distant future of the year 2000. Sadly, the company that commissioned the project (which was likely either a toy or cigarette manufacturer) went out of business before the cards could actually be distributed, and the images remained out of print until author Isaac Asimov rediscovered and published them with accompanying commentary in 1986.

But now that we've lived through that fantastical future, how did these predictions turn out? Let's just say there was, um, a lot of creativity on display. Which is enough to make even the most flawed of these forecasts — of which there are many — even more fascinating to think about today.

Here are 11 delightfully inaccurate visions of the year 2000, according to artists from the late-19th century:

1. Prediction: Firefighters will fly around with batwings on.

This one didn't pan out ... unless maybe Côté was just trying to predict the creation of Batman?

2. Prediction: We'll all travel across the Atlantic in these sweet-lookin' blimp-boats.

Again, not spot on ... although to be fair, I'd prefer this to ever flying standby again.

3. Prediction: We will domesticate whales and use them as transportation.

Nope. If only we'd spent half of the 20th century training whales instead of killing them.(Although there is that dolphin chillin' there, and dolphin-assisted childbirth is a thing that exists in the 21st century, for better or for worse.)

4. Prediction: We will also domesticate giant mutant seahorses.

There's a slight chance all this weird aquatic stuff was their way of warning us about the impending threat of sea-level rise from climate change. Either that or they were warning us about the general existence of Aquaman.

5. Prediction: We'll be hunting seagulls ... from underwater?

Not so correct. But maybe I'm wrong, and we've been overlooking the nutritional value of seagulls for the last century. (Also, why is that woman swimming in a dress?)

6. Prediction: Flying cars will be a thing.

While this image does resemble the traffic outside the Paris Opera just before showtime, our automobiles are unfortunately still stuck on the ground. It does go to show, however, that humans have been obsessed with the idea of flying cars for a long time.

7. Prediction: Aerial wing-flapping hover cars will be our key mode of transportation.

Although perhaps it's only a matter of time until "Uber for aerial wing-flapping hover cars" becomes a thing.

Hopefully, by the time this happens, that orange aerial wing-flapping hover car on the right will learn how to fly without slicing her wings through the other aero-cabs on the stand.

8. Prediction: Automated bathrooms will make our lives much easier.

As clever as today's smart homes are, we still haven't quite figured out how to create a fully-automated bathroom like this. The few failed attempts that have been made at creating robot lipstick applicators were all much less elegant, and much less steampunk.

9. Prediction: Our hardworking barbers and salon specialists will be replaced by robots.

I'm OK with this one not panning out because I'm just not ready to trust an automated tree of spider arms to use sharp objects near my head.

10. Prediction: Our education system will become way more high tech.

While this one is utterly incorrect on a literal level, the image itself works pretty well as a metaphor for our modern education system. Whether that's a good or a bad thing is entirely up to you. (Although we do have EEG technology today, which isn't so different from those helmets...)

11. Prediction: radium.

That's scary. It might help if you wanted to breed a race of ginormous seahorses ... but probably isn't safe to keep in the fireplace as your main source of heat.

Not all of these future visions were as ridiculously off-the-mark as the ones above though.In fact, here are three more that were downright prescient.

1. Prediction: We'll communicate via video chatting.

They totally called the invention of FaceTime/Google Hangouts/every other video chatting service that I use on a daily basis.To be honest, I kinda wish I had a holographic phonograph setup like this. It's way cooler than just staring at my laptop screen all day. (Also I wish I had a sweet mustache like these dudes.)

2. Prediction: We'll see the rise of a mobile society that's not locked into a single location.

Sure, on an overly-literal level, this is basically just a glorified mobile home — which is kind of ironic considering how mobile homes in America are more commonly associated with lower incomes than the wealth that this image depicts.

But more importantly, images like this — and the one below, which accurately predicts the rise of electric trains that have helped to enable more public mass transportation — show that these French thinkers were looking forward to a more adaptable and international society. Telecommuting, remote offices, cross-continental teleconferencing, even the idea of transient living through AirBnB — that's where we are today, and it's exactly where we wanted to be at the turn of the 20th century. And that's pretty freaking cool!

(There's also probably an argument to be made that this electric train suggests a greener and less coal-dependent future, which is cool too.)

3. Prediction: The future will be full of automated industry.

Today, automation and industrialization can be touchy subjects. Are they responsible for job loss? Do they rely too much on questionable cost-cutting practices, such as artificial ingredients and other structural shortcuts?

Those are all important issues to address. But the future portrayed in these images reminds us of the inherent optimism of industry and progress — something that's all too easy for us to ignore today.

farming, industrial, prototypes, jobs, community

See how happy this guy is? He's not freaking out over (and alternately consuming) pesticides and chemicals for the sake of mass production. He's got a big ol' farm, and technology is helping him to make more stuff — and make it fast, so he can sell it and make money and support his family and all that good stuff we like to talk about when we talk about jobs.

Sure, maybe modern factory farming does deserve its less-than-stellar reputation. But at the same time, it's all too easy for us to forget the amazing headway in the creation of life. Now, we can even 3D print ovaries to induce fertility. Think about how amazing that would have seemed in 1899.

And on that note, maybe we should also celebrate the fact that we can 3D print a freaking house today. For all the very real problems that we face in the modern world, technology like that still makes a major difference in a lot of people's lives.

Also these brilliant French futurists clearly foretold of the rise of the almighty Roomba, which is just wonderful on so many levels.

As fun as it is to look and laugh at the imagined futures of the past, this is also a really cool way of evaluating where we are today — and where else we need to go.

It's kind of like writing out your own personal five-year plan ... envisioning the future still makes it easier for us to map out how to get there. Sure, it might not look exactly as you'd hoped — after all, you can't predict every random roadblock you might hit along the way. But it still helps to have some idea of where you're going.

The future is happening all around us, every single day — sometimes so much and so fast that we don't even notice.

Between improving factory farm conditions and domesticating those giant radioactive seahorses, there's obviously still a lot to be done.

Instead of letting ourselves become jaded with the growth we take for granted, maybe this is evidence that we should all try to look back at where we came from, evaluate and celebrate just how far we've come, and figure out a plan to keep moving forward.

The woman from the famous Great Depression photo didn't know about her fame for 40 years.

It's one of the most iconic and haunting photos of all time, up there with the likes of Hindenburg, The Falling Soldier, Burning Monk, Napalm Girl, and many others. It's called simply Migrant Mother, and it paints a better picture of the time in which it was taken than any book or interview possibly could.

Nearly everyone across the globe knows Florence Owens Thompson's face from newspapers, magazines, and history books. The young, destitute mother was the face of The Great Depression, her worried, suntanned face looking absolutely defeated as several of her children took comfort by resting on her thin frame. Thompson put a human face and emotion behind the very real struggle of the era, but she wasn't even aware of her role in helping to bring awareness to the effects of the Great Depression on families.


It turns out that Dorothea Lange, the photographer responsible for capturing the worry-stricken mother in the now-famous photo, told Thompson that the photos wouldn't be published.

Of course, they subsequently were published in the San Francisco News. At the time the photo was taken, Thompson was supposedly only taking respite at the migrant campsite with her seven children after the family car broke down near the campsite. The photo was taken in March 1936 in Nipomo, California when Lange was concluding a month's long photography excursion documenting migrant farm labor.

"Migrant worker" was a term that meant something quite different than it does today. It was primarily used in the 30s to describe poverty-stricken Americans who moved from town to town harvesting the crops for farmers.

The pay was abysmal and not enough to sustain a family, but harvesting was what Thompson knew as she was born and raised in "Indian Territory," (now Oklahoma) on a farm. Her father was Choctaw and her mother was white. After the death of her husband, Thompson supported her children the best way she knew how: working long hours in the field.

"I'd hit that cotton field before daylight and stay out there until it got so dark I couldn't see," Thompson told NBC in 1979 a few years before her death.

When talking about meeting Thompson, Lange wrote in her article titled "The Assignment I'll Never Forget: Migrant Mother," which appeared in Popular Photography, Feb. 1960, "I saw and approached the hungry and desperate mother, as if drawn by a magnet. I do not remember how I explained my presence or my camera to her, but I do remember she asked me no questions. I made five exposures, working closer and closer from the same direction. I did not ask her name or her history. She told me her age, that she was thirty-two. She said that they had been living on frozen vegetables from the surrounding fields, and birds that the children killed."

Lange goes on to surmise that Thompson cooperated because on some level she knew the photos would help, though from Thompson's account she had no idea the photos would make it to print. Without her knowledge, Thompson became known as "The Dustbowl Mona Lisa," which didn't translate into money in the poor family's pocket.

In fact, according to a history buff who goes by @baewatch86 on TikTok, Thompson didn't find out she was famous until 40 years later after a journalist tracked her down in 1978 to ask how she felt about being a famous face of the depression.

It turns out Thompson wished her photo had never been taken since she never received any funds for her likeness being used. Baewatch explains, "because Dorothea Lange's work was funded by the federal government this photo was considered public domain and therefore Mrs. Florence and her family are not entitled to the royalties."

While the photo didn't provide direct financial compensation for Thompson, the "virality" of it helped to feed migrant farm workers. "When these photos were published, it immediately caught people's attention. The federal government sent food and other resources to those migrant camps to help the people that were there that were starving, they needed resources and this is the catalyst. This photo was the catalyst to the government intercepting and providing aid to people," Baewatch shares.

As for Lange, Migrant Mother was not her only influential photograph of the Great Depression. She captured many moving images of farmers who had been devastated by the Dust Bowl and were forced into a migrant lifestyle.

"Broke, baby sick, and car trouble!" is just one of her many incredible photos from the same year, 1937.

She also did tremendous work covering Japanese internment in the 1940s, and was eventually inducted into the International Photography Hall of Fame and Museum and the National Women's Hall of Fame.

Thompson did find some semblance of financial comfort later in life when she married a man named George Thompson, who would be her third husband. In total, she had 10 children. When Thompson's health declined with age, people rallied around to help pay her medical bills citing the importance of the 1936 photo in their own lives. The "Migrant Mother" passed away in 1983, just over a week after her 80th birthday. She was buried in California.

"Florence Leona Thompson, Migrant Mother. A legend of the strength of American motherhood," her gravestone reads.

Communication expert shares 3 simple 'power moves' to not take criticism personally

“If I hear something that’s offensive, I’ll be like ‘okay, that’s trash.’ In my mind, I grab it with my right hand…and throw it.”

jefferson fisher, conversation, conversation tips, communications expert, podcast, jefferson fisher podcast, winning an argument

Standing your ground in a peaceful way is possible.

Even the most skilled small talkers among us might struggle when receiving negative feedback that feels like a personal attack. The temptation to fight back or stonewall is understandably strong. Our darker emotions become ignited, which sets off rejection stories in our mind before any clear thinking can take place.

The result: we dish out the same energy we’re given. Or, we shut down completely. Either way, we don’t get a lot accomplished.


But personal injury attorney and communications expert Jefferson Fisher, who shares all kinds of simple conversation tips, argues that keeping your cool in these heated moments all comes down to three “power moves.”

During a clip of his Jefferson Fisher podcast, the conversation guru first offered up a handy visualization: during moments of facing criticism, he imagines a giant trash can next to him, which collects all the negative feedback. He then “sifts” through the words, separating any snark as “trash” to get to what’s actually worth responding to.

“If I hear something that’s offensive, I’ll be like ‘okay, that’s trash.’ In my mind, I grab it with my right hand…and throw it.”

That concept alone might be enough to avoid getting your feathers ruffled in many sticky situations. But below are the three easy strategies that can go a little further when someone is being offensive.

Power Move #1: Silence

Not saying anything after getting a snarky comment gives the other person the chance to take in their word choice, which Fisher argues often prompts them to apologize on their own.

“You’ve just exposed instead of covering it up…If you just let that silence sit there, oftentimes they go ‘sorry I shouldn’t have said that.’”

Power Move # 2: Acknowledge that the feedback could be true, rather than that it is

In these instances, Fisher encourages saying “Maybe you’re right,” which embraces humility without being a doormat.

Power Move #3: Holding off on the timing

In other words, this means not responding when you are angry and triggered.

To initiate a later time, Fisher suggests saying something like, “Let’s have this out…I don’t really have my thoughts together on that. Why don’t we talk about that at noon tomorrow?”

- YouTube www.youtube.com

Fisher added the caveat that context about who this person is in your life will determine which of these steps you might take. Overall, the main goal stays the same: asserting your value while steering the conversation towards what’s actually productive to discuss. No fighting back required.

You can find more cool tips just like this one on Fisher’s YouTube, Instagram, and TikTok.

In an iconic 1975 clip, a teenage Michael Jackson stuns Cher during hypnotic robot dance duet

The clip marks a turning point in Michael Jackson's iconic public persona.

Cher and The Jackson 5 doing the robot dance.

One of the most distinctive aspects of Michael Jackson's mega-stardom was that he grew up almost entirely in the public eye. He began performing with his brothers at age five and remained a significant figure in American pop culture until he died in 2009.

He burst onto the scene as a child with an incredibly soulful voice. He became an electrifying performer as a teen before rocketing to superstardom at 20 with the release of his first solo album, 1979's Off the Wall. One of the pivotal moments when the public witnessed this transformation came in 1975, when 16-year-old Michael performed with his brothers, The Jackson 5, on The Cher Show.


The Jackson 5 and Cher performed a medley of the band's biggest hits, including "I Want You Back," "I'll Be There," and "Never Can Say Goodbye." But the most memorable moment came when Michael and his brothers broke into the robot dance during "Dancing Machine," and Cher did her best to keep up.

It's fun watching Cher try to fall in line with the Jacksons, while Michael absolutely kills it, gyrating like an animatronic on hyperdrive during his solo.

The Jackson 5 may have helped bring the robot dance into the public consciousness by incorporating it into performances of their 1973 hit "Dancing Machine." But it traces back to mechanical "mannequin" dances from the early days of film. In the 1960s, Robin Shields, a popular mime, performed as a robot on late-night talk shows. By the 1970s, dancers had set those moves to music on shows such as Soul Train.

- YouTube www.youtube.com

In a 2003 interview, Cher said she had to learn the moves on the fly from the Jacksons.

"Think of how hard it was for me to learn to do that, and the guys just knew how to do it. I've been working all day, and they just came on and said, 'Okay, sure, this is how you do it,'" Cher recalled. "I had a lot of fun on that show. It was a lot of work, but I had a lot of fun. You know, and I got to work with some great people."

What's also notable about the performance is that Michael's voice had changed, and he sang in a deeper register than he had as a child a few years earlier.

Things changed for Cher and the Jacksons in 1976

By the following year, things had changed for both The Jackson 5 and Cher. Cher reunited with her ex-husband, Sonny Bono, for The Sonny and Cher Show, which ran until 1977. In 1976, The Jackson 5 left Motown Records for Epic Records and changed their name to The Jacksons. Jermaine Jackson temporarily left the group to pursue a solo career, and he was replaced by his brother, Randy.

Here's The Jackson 5's complete performance on The Cher Show from March 16, 1975:

The two ways people who may not be naturally funny can show they have a great sense of humor

A great sense of humor is one of the most likable traits a person can have.

man luaghing, woman laughing, laughing on date, wine, happy couple

A man and woman laughing on a date.

A sense of humor is often ranked among the most desirable traits in a romantic partner, with women rating it higher than men. Studies show that, in heterosexual relationships, the more times a man tries to be funny and the more a woman laughs, the greater the chance that the woman is interested. If a couple laughs together, the greater the chance of true love.

Why is a sense of humor so attractive? It makes people more enjoyable to be around, helps people bond, and makes awkward or even painful moments more bearable. On a deeper level, humor is a great way to determine whether someone is a creative thinker with a novel approach to solving problems.


But what about people who aren't comfortable cracking jokes and don’t have their brains constantly tuned to the “be witty” channel? Vanessa Van Edwards, a communications expert and author of Captivate: The Science of Succeeding with People, says there are two ways to show they still have a great sense of humor.

@vvanedwards

Is Humor More Attractive Than Looks? | @The Diary Of A CEO

Van Edwards shared her thoughts on an episode of the Diary of a CEO podcast. During the podcast, she noted that there are two roles people can play in a conversation: a driver and a passenger. The driver is the person steering the conversation, while the passenger is along for the ride.

How do people who aren’t great at cracking jokes show they have a sense of humor?

1. Be a great laugher

"So, you are going to be the best passenger ever. You're going to laugh at the joke. You're going to bang on the table. I love table bangers. You know, I have people in my life who are not very funny, but they love to bang on the table when I tell a funny joke, and that makes me feel so good. They don't need to be funny. I'm happy to try. Right? So, if you're not funny, just be very good at hyping up other funny people."


2. Be a great curator of humor

"You also could be a curator of funny. You find the best funny gifts. You find the best funny clips. You share the best funny posts. Like, you don't have to be funny to be a curator of funny. Like, I have a friend who's not that funny, but he has the best clips and memes that he sends me. And so I think of him as funny even though he's never told a joke."

Watch the entire segment here.

- YouTube www.youtube.com

Van Edwards added that if people genuinely want to improve their sense of humor, they can take an improv class to learn how to be funny in the moment. “A lot of humor is just trying things and seeing if they land. So if you're not funny and you want to be and like something good to work on, take an improv class and work on being funny on stage.”

Van Edwards' advice is excellent for those who thought they would never be seen as funny. Her words are a great reminder that even though many great communicators seem to have talent that comes naturally, it's a skill set, and like anything else, there are always ways to learn and improve.

Fascinating 'Dark-fly' experiment has finally allowed scientists to measure evolution in real time

The long-running experiment has tracked changes in over 1,500 generations of fruit flies since 1954.

An experiment running since 1954 has taught scientists valuable information about how evolution really works.

Evolution usually occurs so slowly that it's imperceptible to the naked eye. Simple adaptations can take thousands of years to take hold, far too long for any of us to notice. But just because it's slow doesn't mean it's not happening. Humans, for example, aren't growing wings or gills (as far as any of us can tell), but we are evolving "faster than ever before," mostly in subtle ways such as food tolerance, disease resistance, and brain size.

One fascinating project that was started decades ago has allowed scientists to track and measure evolutionary changes in real time by speed-running evolutionary adaption in a heavily controlled lab setting.


In 1954, Japanese ecologist Syuiti Mori launched what would become one of the longest-running active experiments in the world. He enclosed a colony of fruit flies in glass bottles, covered them with cloth, and placed them in complete darkness.

They would remain there for the next 72 years and counting.


science, scientists, evolution, adaptation, mutation, genes, DNA, fruit flies, humans, health, futurology Dark flies and wild fruit flies look almost identical, but have significant genetic differences. Photo by Luke Peterson on Unsplash

Fruit flies are often used in this type of research because they reproduce incredibly quickly. Eggs typically hatch into maggots within a day or two. Within two weeks, they mature into sexually active adults that begin mating and laying eggs. New generations can cycle rapidly, which makes fruit flies the perfect candidate for tracking genetic changes over time.

Perhaps more surprisingly, fruit flies actually share quite a bit of DNA with humans. Researcher Stephanie Mohr tells Harvard Health that fruit fly genes are about 60% similar to human genes, with even greater overlap in disease-related markers. That makes them a surprisingly effective model for studying human genetics at a simplified level.

Mori's flies bred in complete darkness, rapidly producing generations that had never seen the light of day. Today, the experiment continues under successive generations of leading researchers, during which the colony has produced more than 1,500 generations.

Researchers access, feed, and study the flies using a weak red light that the flies cannot detect. For decades, they've been able to perfectly control the conditions from generation to generation. The Genetics Society of America writes: "The stock of flies has now spent more than 1,500 generations without light. In human terms, that would be like sequestering generations of our ancestors in the dark for 30,000 years."

Adaptation is slow, but that is more than enough time to measure changes, if any occur.

The research team quickly discovered that after several generations, the new variety they had created, fittingly called "Dark-fly," performed better in darkness than wild flies.

The two subspecies look nearly identical, but the Dark-fly has longer head bristles used for sensory perception, a stronger sense of smell, and a tendency to lay more eggs in dark conditions.

Researchers even created mixed colonies of wild flies and dark flies, allowing them to interbreed in darkness, and found that Dark-fly DNA was more likely to be passed on to future generations.

In 2012, the full genome of the Dark-fly was sequenced by Naoyuki Fuse, who had taken over the project a few years earlier.

According to Bioedonline.org, "Fuse and his colleagues sequenced the dark-fly genome, identifying 220,000 single-letter differences in its DNA and several thousand larger DNA insertions or deletions, compared with a normal fruit-fly strain."

The team was able to pinpoint which genes changed over time and how, offering rare insight into how evolution works.

Scientists are quick to note that living in darkness does not directly cause changes in the flies' DNA. Instead, natural selection favors mutations and traits that help the flies thrive, making them more likely to be passed on to future generations. Some differences may simply be due to random chance, or genetic drift.

Adaptations in extreme environments have been observed before. Some insects, including bedbugs, are becoming resistant to pesticides. The Mexican tetra, also known as the blind cave fish, has lost functional eyesight after generations of living in pitch-black caves. And a number of animals have adapted to rapidly warming climates.

But recording and measuring these changes in a controlled laboratory environment is extremely rare. Outside the Dark-fly experiment, other long-running studies have tracked colonies of E. coli and yeast under various conditions. But there's something incredibly exciting about observing a living, breathing species as it rapidly adapts to thrive in unnatural conditions.

One day, studies like this one could help scientists rewire human brains and genetics to protect against disease, among other amazing applications.
