Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
For real though, the only sports competitions I’ve been to live in the past decade have been robot sports.
Why would I pay money to see a human take a ball from another human, when I can pay less to watch a robot shoot flames and saw open another robot gladiator style?!
