Personally, if I only used GPUs for gaming I'd be happy with an RTX 3080 and probably wouldn't upgrade until the next console generation released. I am content with 1440p 60-120fps depending on title. DLSS quality looks near native or even better than native to me. Ray-tracing is nice, but I could wait until next-console-gen when Nvidia accumulates enough neural-rendering techniques in its feature-set to get us real-time path-tracing with a decent denoiser and more games support these features.
The XX90 series targets the same demographic that the Titan cards did -- prosumers who use GPUs for compute tasks but don't need the Quadro-only features.
There isn't competition in this space to bring prices down because AMD and Intel are way behind on getting traction behind their APIs. If either of them had API-parity (or close enough support) with CUDA then Nvidia probably would compete on things like VRAM capacity on consumer cards. There is a lot of hunger for VRAM in the prosumer space. But if they don't have to, then they don't want to eat into their market for actual professional cards and chipsets.
As for just keeping the pace of prior decades in terms of raw compute, we need a paradigm shift and that requires the coordination of multiple companies in the industry in general, not just the GPU designers, but the computing industry as a whole.
