They improve yields on their flagship 3090s by rescuing ones that fail as 3080, 3070 or the highest bin that they meet specification. They wouldn't become a 2060 as that uses a different architecture. The manufacturing processes will also improve over time and at some point demand will dictate binning over yeild. Chips that are capable of better performance are restricted and sold as lower end cards. If yield is no longer an issue is simply more profitable. Back in the day it wasn't uncommon for enthusiasts to take lower end cards and bios mod them for equivalent performance, but now features are often disabled in silicone.
