Honestly I think engineers of all kinds can benefit from more study of biological systems. As an engineer myself, I find there's a lot of inspiration to be gained by looking at life and understanding how it works. My primary work is controls and learning that biological muscle operates as bang bang control was mindblowing. Like look at the agility and complexity achieved by essentially a fuck load of on off actuators. It shows how far you can go with extremely simple methods and honestly helped me chill the fuck out about making everything perfect.
