This isn't really true from the recreational card side, nVidia themselves are reducing the number of 8GB models as a sign of market demand [1]. Games these days are regularly maxing out 6 & 8 GB when running anything above 1080p for 60fps.
The prevalence of Unreal Engine 5 also recently with a low quality of optimization for weaker hardware is causing games to be released basically unplayable for most.
For recreational use the sentiment is that 8GB is scraping the bottom of the requirements. Again this is partly due to bad optimizations, but games are being played in higher resolutions also, which required more memory for larger texture sizes.
