Here's a sample of 10, drawn randomly:
2020-2050: Phone calls entail three-dimensional holographic images of both people.
This is totally possible. We could even do it on phones with fairly mundane consumer technology. We can do it with glasses, even. People just don't care. The prediction has yet to land but in spirit is correct.
Centuries hence: Computer intelligence becomes superior to human intelligence in all areas.
Anyone doubting that this will be true within centuries is nuts.
2009: People can talk to their computer to give commands.
At most a couple years early in technicality, and in spirit over a decade early.
2009: Computer displays built into eyeglasses for augmented reality are used.
True today, if not a particularly popular product, and later than suggested.
2009: A $1,000 computer can perform a trillion calculations per second.
Definitely true today. I think this was basically on time, too.
2019: Most people own more than one PC, though "computer" no longer means laptop or box-plus-monitor.
Freebie.
2019: Most learning is via adaptive courseware presented by computer-simulated teachers; human adults are counselors and mentors, not instructors.
We obviously could do this today, though it might not be a great idea for the students. Early, and socially blind, but basically right about possibility.
2019: Prototype personal flying vehicles using microflaps exist, primarily computer-controlled.
Basically wrong. There are eVTOL companies aiming for this, and people do have camera drones, but the sense it was meant wasn't predictive.
2019: Human-robot relationships begin as simulated personalities become more convincing.
Early, subscale, and fought against by providers, but this is a thing.
2029: Massively parallel neural nets constructed by reverse-engineering the human brain are in common use.
Ok people will mob me for saying this, but this was more right than wrong. Definitely at least a bit wrong.
