He believes engineering solutions are often preferred over invasive biological modifications to improve human performance in extreme environments.

“In the early days of space exploration, there was all this talk about modifying the human physiology to accommodate the stress and strain on our body in space. Mhm. And in almost every case, they came up with an engineering solution to the problem rather than a biological one”

The military researches how extreme conditions like noise, panic, heat, and insects negatively impact human performance and combat effectiveness.

“Human. Yeah. Extreme heat and loud noise and fear and panic and flies and diarrhea and all the things that people don't necessarily think about, but the military thinks about because it knocks soldiers out of commission.”
