> Most business transactions or information inquiries involve dealing with a simulated person.
"Most" is strong, but virtual agents are definitely widespread and fairly heavily loathed.
> Most people own more than one PC, though the concept of what a "computer" is has changed considerably
Undoubtedly correct.
> Cables connecting computers and peripherals have almost completely disappeared.
> Rotating computer hard drives are no longer used.
Very strong trendlines, although "almost completely" and "no longer" are not accurate.
> Massively parallel neural nets and genetic algorithms are in wide use.
Depending on how you define "wide use". Applications that rely on neural nets are very heavily used, but neural nets are closer to a niche technology than a widespread algorithmic hammer.
> All students have access to computers.
In developed countries, yes.
> Public places and workplaces are ubiquitously monitored to prevent violence and all actions are recorded permanently. Personal privacy is a major political issue, and some people protect themselves with unbreakable computer codes.
Scarily, this is more true than not.
... That's pretty much the lot of the 2019 predictions that came close to coming true. At best that's a 20% hit rate for predictions, although many of these hits require reinterpreting "most" as "many" and so on.
