1. The crypto bubble (if it is that) collapses in a way that doesn't just make it worth less, but like an old fashion no one wants any more.
2. More chip fabs open up and clear the backlog.
3. Makers somehow make a GPU useless for mining but fine for gaming. I've read that disabling an instruction here or there might do it. No idea if that's true, but conceivably there could be some way to do this. In current year, I can imagine some hamhanded phonehome/secure module system that won't work except on signed code, which of course all the big game makers would have no trouble implementing. All of this will probably fail to do anything except deter hobbyists, but isn't that how it goes?
For the time being, I'm not unhappy getting off the constant-upgrade hamster wheel for a while. There are very few games that actually need the latest GPU and none that I personally care about, but I'm not a gamer.
Not only crypto is still running, companies want to push nfts. Not to mention increasing demand in ai / ml sector to cloud providers want to ramp up their ai capabilities.
