On 3 April 1973, a Motorola engineer named Martin Cooper stood on a Manhattan sidewalk, held a brick of plastic and wire to his ear, and called his rival at Bell Labs to gloat. His phone weighed 1.1 kilograms and gave him about thirty minutes of talk time. It also had a very obvious ancestor: the flip-open communicator that Star Trek had put in Captain Kirk’s hand seven years earlier. Cooper admitted as much — the show, he said, was where the idea came from.
That pattern repeats across the last six decades. A writer or a set designer sketches something impossible. An engineer spends twenty years building a bad version of it. A generation grows up assuming it was always there. The technologies that were once science fiction rarely arrive all at once; they arrive badly, then quietly, then everywhere.
The pocket supercomputer was drawn before it was built
Writers kept getting the shape right and the economics wrong. The PADDs on Star Trek: The Next Generation in 1987 were slab-like touchscreens, though crew members carried stacks of them, one per document, because nobody imagined a single device holding everything. The iPad shipped in 2010 with the form factor and without the stack.
The wrist phone has an even longer paper trail. Chester Gould drew Dick Tracy’s two-way wrist radio in 1946, added a television screen in 1964, and the Apple Watch turned up in 2015 with a heart-rate sensor the comic strip never thought to include.
What the fiction consistently missed was cost. The DynaTAC 8000X sold for $3,995 in 1983, close to $13,000 in today’s money, and it did one thing. The phone in your pocket does several thousand things and costs less than a week of groceries.
Video calling was ready fifty years before anyone wanted it
Fritz Lang put a videophone in Metropolis in 1927. AT&T demonstrated the Picturephone at the 1964 World’s Fair and launched commercial service in Pittsburgh in 1970, complete with dedicated booths in office lobbies. It flopped. The hardware worked fine. The network effect didn’t: nobody you knew had one, so there was nobody to call, so nobody bought one.
Social distance did what five decades of marketing couldn’t. Zoom reported roughly 10 million daily meeting participants in December 2019 and around 300 million by April 2020. The underlying technology had barely changed in the intervening months. The social permission had.
Self-driving cars took the scenic route
KITT drove himself in 1982. Johnny Cab took Total Recall‘s passengers for a ride in 1990. Minority Report had maglev pods in 2002. The real versions came slower: the first DARPA Grand Challenge in 2004 ended with no entrant finishing the 142-mile desert course, and the best vehicle managed about seven miles before catching fire. Stanford’s Stanley completed the route in 2005, and Google’s team started hiring.
Two decades on, Waymo runs hundreds of thousands of paid rides a week across Phoenix, San Francisco, Los Angeles and Austin. All of it geofenced, all of it pre-mapped, none of it ready for a snowstorm in Buffalo. The fiction promised a chauffeur. We got a very careful driver who only works in places it has already studied.
Gene editing stopped being a metaphor
Aldous Huxley wrote Brave New World in 1932, complete with hatcheries and designer embryos. The working version arrived with a far less literary name. CRISPR-Cas9 was published as a gene-editing tool by Jennifer Doudna and Emmanuelle Charpentier in 2012 and won them the Nobel Prize in 2020. In December 2023 the FDA approved Casgevy, the first therapy built on CRISPR, for sickle cell disease. It edits a patient’s own blood stem cells so they produce foetal haemoglobin instead of the misshapen adult kind, and in trials it freed people from pain crises that had run their entire lives.
Designer babies remain firmly on the shelf. A cure for one brutal genetic disease does not, and that is probably the version of the future most of us would have asked for.
Robots shaped like us, priced like cars
Humanoid machines have been a screen staple since Maria in Metropolis and mostly a punchline in the lab. That changed faster than most people noticed. Figure’s humanoid robots pulled in a billion dollars of funding and went to work on a BMW line in Spartanburg, while Boston Dynamics, Tesla and a dozen Chinese startups chase the same target.
Hands are the hard part. A robot that walks across a factory floor is a solved problem. A robot that picks a single cable out of a tangle without crushing it is not, and every demo video quietly cuts before that bit.
The tractor beam turned out to be light itself
Physics fiction ages strangely. Arthur C. Clarke’s geostationary satellites, proposed in a 1945 letter to Wireless World, now sit in the sky exactly where he described them. The transporter never worked. Something adjacent did. The weird corners of quantum mechanics that were once pure thought-experiment are now engineering: entanglement distributed over fibre, quantum teleportation of states demonstrated as far back as 1997, and optical tweezers, which use focused laser light to hold a living cell steady precisely enough to earn Arthur Ashkin a share of the 2018 Nobel Prize.
A tractor beam that moves atoms instead of starships. Not what the pulp covers promised, but real, and in a lab near you.
AI: the part the stories got wrong
HAL 9000 was polite, competent and homicidal. What we actually built is fluent, eager to please and prone to inventing citations. Neither version matches the fiction, and where this lands is genuinely unsettled; the murky middle between AI utopia and collapse is where most serious people now put their chips.
The more interesting question was never whether the machine turns on us. It is whether there is anything it is like to be one. Ray Nayler’s work on animal minds and non-human consciousness is a better guide to the next ten years than any rogue computer plot, because it starts from the assumption that intelligence might be genuinely alien and still worthy of respect.
Still sitting on the shelf
Plenty of promises remain unfulfilled, or fulfilled in forms nobody asked for:
- Teleportation of matter. Quantum teleportation moves information between particles, not people. Nothing larger than a photon has moved an inch.
- Hoverboards. The Hendo board genuinely floats, but only above a copper surface, and only for a few minutes at a time.
- Jetpacks. They exist, they cost more than a house, and they fly for under ten minutes. That is roughly a commute across a car park.
- Flying cars. Slovakia’s AirCar received a certificate of airworthiness in 2022. It also needs a runway, which rather defeats the purpose.
- Cryosleep. Suspended animation is still a medical maybe and a marketing certainty.
Watch what is in the fiction aisle right now instead. Brain-computer interfaces that let a paralysed man type at ninety characters a minute, lab-grown bladders, asteroid mining outfits with actual launch contracts. The badly made version of each is already being assembled in a university basement by someone with a grant and no media training.
Give it twenty years and a falling cost curve. The props get built eventually. They just take longer, cost more, and arrive in worse form than the story promised, right up until the moment a child picks one up and cannot imagine life without it.
