I think everything you noted as a downside is why, in part, things like Pickleball and Disc Golf took off in the last 5 years.

They’re similar to things we know, but different enough that they haven’t been optimized out of reach by normals, or at least perceived as such, and both have a relatively cheap barrier of entry to get started.

I think we may find 20 years from now the dominate sports have changed up a bit. I have heard that the NFL and MLB for instance are worried about the incoming decline of their sports because they aren’t nearly as popular with people under 35 compared to basketball and other up snd coming sports
