I don’t think you understand how evolution works. There is no evolutional pressure on humans to run long distances, jump far or high. And even if there suddenly were, it would take generations for noticeable changes. It’s much more likely that some parents let their kids be CRISPRd to create more red blood cells which would grant them an endurance boost or other such changes. That will probably happen in our lifetime.

Besides, your ostrich example is not helpful. A snow albatross is as tall as a small human and also has two. Maybe we will grow wings and fly!

We do know what human bodies are physically capable of. You can literally calculate that. With genetic outliers you can push this slightly, but not by a huge margin. There is a reason why so many records are still standing after 30-40 years. For a marathon, 2 hours is about the limit of human bodies. We reached that in 2023. Maybe someone can eke out a minute or two more, but without genetic manipulation or doping that’s it. The world records for long jump were set in 1988 for women and 1991 for men. The record for high jump was set in 1993. For these sports we have reached what human bodies are capable of. If they are ever broken, it will be by a few centimeters. No human will suddenly jump 10 meters.

We are very close to the limit of what human bodies can do without cheating. Genetic outliers who can slightly push these limits might exist, but they won’t suddenly jump 10m, rather narrowly crack the 30 year old record of 8.95m, for example. And someone might run a clean 2 hour marathon, but there won’t be anyone running it in 90 minutes. Until we do genetic manipulation or allow doping, the old records will stand or will only increase marginally.

What’s a boomer shooter?

Katherine Long sounds great. Her second attack, with fake board meeting notes is so dedicated.
