Except genetics is taking a backseat to science in some cases. Cases that are normally considered cheating. Except for a small minority where they're allowed to do it. Like if you were to show up to a gaming LAN party with a ton of hacks/mods, because you were bad at the games being played, you'd be a cheater. Even if you try justifying it saying you're bad at those games, and that you need computer science bots to help make you better at it, you're still entering in to the competition with an unfair advantage and not competing with the other players in a fair way. And even if other players beat you, you still cheated and made it a lot less fun for anyone who lost to you in the process. And to demand that the competition completely change how players are sorted / paired, so that bot players/cheaters get representation and can participate too, totally undermines the whole point of the event.

Idk. I agree that it's theoretically possible to implement some sort of max T level via medical sources or whatever, but that's totally impractical for most levels of the sport, I would imagine. It's a huge hurdle to put for event organizers to meet, in order to include a very small sub set of the population. There need to be some limits on that, otherwise the cost / effort to put on events for anyone becomes intolerable for organizers/administrators.
