In 2017 I wrote about five technologies that felt like science fiction arriving early: AI that beat world champions, consumer 360 cameras, gene therapy for inherited diseases, super-efficient solar cells, and trucks that drive themselves. Nine years later is the perfect moment to check the receipts — which of these changed the world as promised, which are still cooking, and which quietly faded? The answers surprised me, and they say a lot about how to read tech hype today.
Quick Answer
All five 2017 technologies survived — but at very different speeds. AI (AlphaGo's heirs) rewrote the entire software industry by 2026; gene therapy produced real approved cures; self-driving trucks run commercially in Texas; 360 cameras found a niche; and next-gen solar cells are still climbing from lab to factory. Here's the honest scorecard for each.
1. Artificial Intelligence: From Beating Go Champions to Everywhere
Then (2017): DeepMind's AlphaGo had beaten the world's best Go player, and modified versions were teaching themselves chess and shogi from scratch. Impressive — and easy to dismiss as a parlour trick for board games.
Now (2026): This was the technology that broke every prediction. The self-learning techniques behind AlphaGo scaled into large language models, and by 2026 AI writes code, drafts legal documents, edits photos on phones and answers the phone at thousands of businesses. The 2017 conversation was "can machines think?"; the 2026 conversation is which jobs get restructured and how fast. Of the five technologies here, AI didn't just arrive — it reset every other industry on this list. I use AI tools daily for work I genuinely couldn't delegate in 2017, and so do you, whether you opted in or not.
2. 360-Degree Cameras: From Gimmick to Niche Standard
Then (2017): 360 cameras finally hit consumer prices, promising immersive photos and the next wave of social content.
Now (2026): The consumer hype settled into something healthier. The 360-camera promise of "the next photography revolution" never arrived — but the technology quietly became standard kit for motorcyclists (360 crash cams are near-default in touring vlogs), real-estate tours, VR content and action-sports filming, with brands like Insta360 turning it into a stable product category. A muted outcome next to AI's, but an honest one: a real tool found its real users. If you've watched a first-person moto vlog recently, you've watched 2017's revolution succeeding quietly.
3. Gene Therapy: The Slow Win That Actually Cures
Then (2017): The year gene therapy stopped being theoretical — regulators approved therapies for inherited blindness and leukaemia (CAR-T cell therapy), replacing crude bone-marrow transplants for some immune disorders.
Now (2026): Gene therapy is a working branch of medicine. The approved catalogue has grown from a handful of therapies to dozens globally, and 2023's approval of the first CRISPR gene-editing therapy (for sickle-cell disease) marked the line from engineering viruses to engineering genomes directly. The honest caveat: these cures remain enormously expensive — treatment costs in the millions per patient — and access is the industry's unsolved problem. But "incurable genetic disorder" is no longer a permanent sentence, which is exactly the breathtaking part promised back in 2017.
4. Next-Generation Solar Cells: Still the Future, Still Promised
Then (2017): Lab breakthroughs promised solar cells far beyond conventional photovoltaics — including thermophotovoltaic designs that convert heat to light and then electricity, discussed as potentially doubling efficiency.
Now (2026): The physics delivered; the economics took longer. Thermophotovoltaic cells passed 40% efficiency in landmark research, and perovskite and tandem solar cells — the other 2017-era hopes — finally began moving from lab curves to production lines in the mid-2020s. Meanwhile ordinary solar became the cheapest electricity in history, driven by scale rather than exotic cells. This is the "wait longer than the hype cycle" entry: the technology works, and the 2030s grid will likely contain it — but a 2017 reader expecting panels of the future by now is still installing conventional ones. Solar is the reminder that manufacturing scale is its own decade-long technology.
5. Self-Driving Trucks: The Predictions Were Late — Then Real
Then (2017): Self-driving trucks were supposed to flood highways "by the end of the year." That was hype — the technology wasn't remotely ready.
Now (2026): The prediction was early by nearly a decade, but it finally came true on specific routes. Aurora has been running fully driverless commercial trucking between Dallas and Houston since April 2025, passing 100,000 driverless miles and scaling toward a couple hundred trucks; Kodiak's autonomous trucks have hauled thousands of commercial loads in Texas energy logistics. The mature lesson: autonomy didn't arrive as an everywhere-all-at-once revolution — it arrived as fixed regional freight lanes where highway driving is highway driving. Your long-haul trucker cousin still has a job; the freight between two Texas depots increasingly doesn't have a human in the cab.
What 2017's Hype List Teaches About 2026's
Reading this scorecard, a pattern I can't unsee: none of the five disappeared, and none arrived on time. AI overdelivered on a timeline nobody drew; trucks underdelivered by nine years and then worked; solar is mid-flight. When you read 2026's breathless lists — quantum computing, humanoid robots, AI agents — expect the same: real technology, wrong deadlines, and the biggest changes arriving in the direction nobody was pointing at.
FAQ
Why revisit technologies from 2017 specifically?
2017 sits at a useful hinge point: modern AI's foundations (self-learning systems), consumer 360 cameras, first-generation approved gene therapies, record-efficiency solar research and the self-driving-truck hype peak all trace to that year. Nine years is long enough to separate genuine trends from press releases — most hype cycles resolve within a decade.
Did self-driving trucks really become commercial by 2026?
Yes, but narrowly. Aurora began fully driverless commercial freight between Dallas and Houston in April 2025 and has since logged over 100,000 driverless miles; Kodiak runs autonomous trucks commercially in Texas energy logistics and went public. This is real revenue service, not testing — but it's regional highway lanes, not the anywhere-anytime autonomy promised in 2017. Expansion (including California permits) is underway.
Is gene therapy actually curing people now?
Yes. Since the 2017 approvals for inherited blindness and blood cancers, regulators worldwide have approved dozens of gene and cell therapies, and the 2023 CRISPR-based therapy for sickle-cell disease showed genome editing curing a condition rather than managing it. The catch is cost — several million dollars per patient — which limits scale. The medicine works; the economics are the unfinished part.
What happened to 360-degree cameras?
They matured into a solid niche instead of a revolution. The 2017 consumer boom faded, but 360 cameras became standard for motorcycle vlogging, action sports, VR content and virtual tours, with Insta360 and GoPro maintaining healthy product lines. If your metric was "everyone will shoot 360 photos," it failed; if it was "immersive capture becomes accessible," it quietly succeeded.
Which 2026 technologies should we track with the same skepticism?
Apply the 2017 scorecard to today's list: humanoid robots and quantum computing look like solar (real progress, industrial-scale payoff later); AI agents look like trucks (later and narrower than promised, then real); and whatever quietly improves inside your existing apps — like AI did — is likely the actual revolution. Watch what gets cheaper every year, not what demos best.
