Idiocracy is an entertaining comedy, but it isn't realistic in the slightest.
Idiocracy uses a eugenicist premise (and the problem with that premise is a whole can of worms unto itself) to set up a world where everyone is an idiot, no exceptions. But they're well-meaning idiots, and they have enough sense to be able to defer to the one and only smart guy in the room who ultimately saves the day.
The real world is suffering not because the people in power are stupid, but because the people in power are selfish and evil, and because they are smart enough to manipulate people who are dumber than them. There's only one exception here, but the one guy who is a true idiot is a puppet being controlled by smart evil people.
The Fediverse is ActivityPub, because ActivityPub is how Fediverse servers talk to each other. BlueSky does not talk to Fediverse servers, so it cannot be said to be part of the Fediverse.
$80 software is rough, but I don’t actually think $450 for the hardware is as unreasonable as people are making it out to be. It's not like packing this hardware into a tablet form factor is gonna be cheap.
Remember when the PS3 was $599 in 2006? Adjusted for inflation, that's $948 today.
The idea of smart people going extinct is simply not how genetics works. That is flat out unscientific.
