Depending on your definition, this actually is not peak performance.
Subways are.
Obviously, the tunnels are absurdly expensive, but nothing moves as many people as quickly around a city as a subway.
They’re also extremely reliable, meaning people are even more likely to actually use them, and their above-ground footprint is essentially zero.
I genuinely like this idea, because it would allow to reach both goals.
The problem I see is that this would probably go down the same as the bodycam idea, with inconvenient recordings vanishing due to “technical issues”.
You’d need an independent third party doing life recording and delayed release. Subjectively, the US don’t have a great track record with these.
Easier idea: Just publish last week’s encryption key. Probably won’t happen because some tech supplier will lobby for a more expensive solution.
Anyone who hits enter on a dd command without triple-checking it gets exactly what they deserve.
The genre is usually divided into “soft” and “hard” fantasy.
Cyberpunk is generally considered hard fantasy, as is stuff like The Expanse or Interstellar.
Star Wars is unabashedly soft SciFi, it’s a straight Fantasy story in space.
Star Trek is a half-breed - it pays some lip service to scientific “plausibility”, but much of it stretches that envelope beyond the breaking point. Scientific accuracy was never the point of the series to begin with.
