It's probably just hope but '90' series cards selling for going on £3,000 for not always top end model and the not really '80' series cards below them (massively cut down from the 90 series) for circa £1,200 isn't really a sustainable PC eco system. I could half justify the extreme cost of 4090 because it was so much faster than both the previous generation and anything else from the same generation (perversely offering some of the best performance/ per £ ratio of any 4000 series card) it's clear now that the '5000' series has done next to nothing to actually improve on the architecture of the previous generation. They've just taken an already big and sometimes teetering on dangerously power intensive card (especially considering what they expect of the power connector for it) and made it even bigger and jacked up the actual typical price far in excess of any % improvement gained. If the 5090 was a true 'Halo' card more akin to a Titan of days past its price might make more sense for the small 'price is pretty much no object if I'm getting the current best crowd' but the 5080 being so far behind means, there's a huge gap where a top end (but now quite 'halo' card should be).
I do think, at least for Nvidia, that the AI bubble will somewhat burst as new companies get in on the market. Hopefully AMD can continue to get their act together more and return to being a more viable alternative to Nvidia across a wider performance range.
Either that or more of us will have to hang onto our graphics cards a lot longer and dev's might actually have to start spending more time optimising their products to get more out of existing hardware again!
