Ok, first you lump everything into 8GB problem - that's not how I put it. There are 8GB issues - very well documented and known by now, with multiple videos by Daniel O., HUB and other known channels, hence no need for me to give specific examples, as said channels shown those in details. By the way, there's also a few showing how 3060 12GB beats easily 4060 8GB in I.J. as well. That aside, there are also pure performance issues with PT in mainstream cards being mostly just unusable (unless you cut it down, but then it's not actually PT anymore, is it?). Not the same thing, but both issue touch mainstream GPUs.
TAA doesn't really matter, gamers don't care about graphics that much or else they'll buy a (sufficiently) faster hardware.
Ok, there's a big difference between cutting down details to improve performance on lower end hardware and muddling details even on top hardware needlessly - neither are RT reliant. Fun fact, TI in newest video dismantled frames of another game and commented about optimisations in some areas allowing RT implementation without increasing frame time - there goes yours (and others) theory of him not liking RT, where he clearly states he loves and wants to use RT (where and when it makes sense).
To summarise, you seem to live in an odd denial state, where you claim don't want optimisations in games because... you want them to look muddy? And you seem to prefer them to require, for the same level of visuals, as high-end GPU as possible. Very weird form of masochism that, but you do you, I give up on talking sense to you.
