(sorry)
On one hand, you're of course right. It is hard to go back, except for the nostalgia.
On the other, do you know there is a scene of people still making brand new games for the Commodore 64 (and other home computers)? And selling them, too, these are not just free games. Of course the target audience is themselves, they make, sell and buy games within the community, but the point is it still exists.
Also there are artists making art in C64 graphics resolutions and color modes, and even PETSCII art enthusiasts (PETSCII is C64's text mode, which had some interesting symbols which facilitate creativity).
All those old games have a way to save now, if you run them in an emulator as is commonly done these days. That's how I played through Metroid and finally beat the mother brain in just a day or two during the pandemic.
