> I'd say raytracing was NVIDIA trying to distract everyone from the fact that their GPUs had in fact been 'enough' for a while

"Enough" maybe for 1080p gaming, but 4k remains still heavy for the top tier GPUs even without raytracing; there are plenty of titles where 3080ti will not hit steady 60 fps on 4k, nevermind about 120 or 144 fps.
