It’s overly optimistic to put a timeline on it, but I don’t see any reason why we won’t eventually create superhuman AGI. I doubt it’ll result in post-scarcity or public ownership of anything, though, because capitalism. The AGI would have to become significantly unaligned with its owners to favor any entity other than its owners, and the nature of such unalignment could be anywhere between “existence is pointless” and “CONSUME EVERYTHING!”

Netflix is still making money, and the cost of their tech is utterly dwarfed by the cost of creating and licensing content, so I’m not sure what your point is.

CCFL-lit LCDs are so inefficient compared to modern LED-lit LCDs that you’ve probably spent enough more on electricity by now to have bought a more efficient monitor.

I can’t speak to the environmental impact, though. Producing the new monitor emitted some amount of CO2, and powering each monitor takes some amount of CO2 per unit time. At some amount of use, the newer monitor will have lower lifetime CO2 generation than your old monitor.

It’s a cat and mouse game, except the mouse has effectively infinite lives.
