Sadly, i don't think GPU prices will ever drop. The only reason would be if a new competitor comes up with something on par or better than the current tech. For CPUs, we've reached the limit already. Nonetheless, their's still some hope with a tech called optical computing.

Computer power increase became meaningless because companies juste use it as an excuse to not optimize their software anymore. The best exemple is how everyone basically uses a whole browser (chromium ) just to show some GUI. The steam client and discord are two big software that comes in mind using this but it's spreading fast and I found a GUI for aria2c that weights more than 60mb while aria2c itself is a few megs, but even worse some manufacturers are using it for their mouse and keyboard drivers for god sake.
