I wished there were scene coders dedicated on the 286/386/486s

The C64 scene is a creative community where someone could see what would happen if you kept pushing limits on a 25 years old machine where the hardware still remains the same. There was a time I thought I have seen everything on this machine but then new stuff are coming up breaking old records or creating entirely different styles of demos. It seems to never end. I am really wondering what could be done in other hardware (either 8bit/16bits or PC) with such dedication.
