Baseball Is Better Than It Used to Be

It's taken as axiomatic now that baseball players today are better than they've ever been. But how would it change baseball fandom if it were clear that players from the past really were better than modern players? Say for instance, that baseball ends up so thoroughly out competed in the 21st century by pickleball and Overwatch that it no longer attracts the best athletes. Would we lean into enjoyment of baseball's niche weirdnesses and become more like reenactors? Or would it make no difference at all?
