But if everything is really a convexity problem what are you trading for tractability? 

Ironically, it’s like lossy compression - because it’s lossy. Optimal control gives you a more simplified version of reality. Don’t even get me started on how everything engineering wise that works is a essentially a handy wavy *guesstimate* - I’d honestly start driving cars and planes too

Honestly I think this is fundamentally the essence of engineering in general. You’re constantly trading fidelity, optimality, and expressivity — for tractability and that’s wild — because it works

Essentially you are trading what is ontologically true for solvability, you’re lying about reality so you can solve it - it’s sort of the opposite of art

Engineering is the only constructive lie!
