      "class of complexity problems with optimal algorithmic solution in polynomial time" = any problem you can solve in O(n^k) for any k = P NP = problems you can _check if you solved correctly_ in O(n^k) but we dunno if there's a way to _solve_ them in O(n^k)

      Well I probably can't convince you, succinctly, that I'm not just parroting it but maybe you'll decide to care if people you otherwise enjoy talking to are talking to you about this

      The main benefit, in my experience, to learning about complexity classes (P, NP), is understanding when I'm _wasting my time_ trying to solve an impossible problem.

      Replying to @simpolism @danlistensto and

      So even if it takes you a few hours upfront to understand the P=NP problem statement, you'll end up avoiding hours spent thinking up bad/wrong algorithms for NP-complete problems.

      It also teaches you how to _frame_ problems more correctly, which is important if you want a shot at solving them. But I guess in practice you can hire an ex-Ph.D. student to do these things for you.

      Funny example, given that you know the name Bram Cohen because he spent years absorbing dry, abstract maths.

          Which brings us to the efficient market hypothesis and P = NP! Maths are public information. You can still make money with them. QED af

          You want a job with a decent salary? Javascript. You want a conceptual toolkit applicable to many problems (including learning JS), that could lead you toward novel solutions? Math.

          If you're capable of doing advanced math, Javascript is an exercise in tedium. Just pay someone from a bootcamp to build a UI for you and instead focus on solving harder problems.
