Honestly GPU mining ending would be an amazing thing. There is nothing but negatives coming out of GPU mining for the vast majority of people:
1. GPU mining sucks up absurd amounts of power. This is terrible for the environment because this is just a straight increase in the amount of electricity required for the grid to function - this will inevitably result in more electricity being produced via dirtier methods as opposed to renewable methods because the amount of renewable electricity we are producing is far outpaced by the increase in electricity required due to mining.
2. It, for an incredibly long time, caused there to be virtually no stock in the GPU market for people using them for purposes that aren't mining (gaming, research computing, etc), especially in the middle of the pandemic when chip supplies were already at an extreme low. It also caused scalpers to crawl out of their various holes because they saw they could make a profit by overcharging people extreme amounts for the limited supply of GPUs that weren't being used for mining.
