I see. That I can mostly agree with. I really don't like the temporal artifacts that come with TAA either, though it's not a deal-breaker for me if the game hides it well.

A few tidbits I'd like to note though:

they announce them way too early, so people are waiting like 2-3 years for it.

Agree. It's kind of insane how early some games are being announced in advance. That said, 2-3 years back then was the time it took for a game to get a sequel. Nowadays you often have to wait an entire console-cycle for a sequel to come out instead of getting a trilogy of games on during one.

Games shouldn’t be relying on them and their trade-offs are not worth it

Which trade-offs are you alluding to? Assuming a halfway decent implementation, DLSS 2+ in particular often yields a better image quality than even native resolution with no visible artifacts, so I turn it on even if my GPU can handle a game just fine, even if just to save a few watts.
