"What is P vs NP and how does it relate to human knowledge?" Avi Wigderson (Turing Award & Abel Prize winner): "In a very basic way, all the problems we want to solve are really NP problems. A subset of it is the problems we can solve. So the question of P versus NP is whether we can solve all the problems we want to solve, whether we can know everything we want to know. This is basically about the limits of our knowledge. You can think there is no limit to what we may want to know but I claim that essentially in any human endeavor, what people are searching for have the property that when a solution is found, it is easily recognized. NP are all problems that we can honestly say we really want to solve and P are those that we can solve. Whether they are equal is just the very fact that a solution can be easily recognized would imply that it can be efficiently found. That means that we can know everything we ever want to know, it's a fundamental question about human knowledge."

You can't engineer luck. Cleanest phrasing of P vs NP I've heard. NP is the magical computer that always tells you which path to take. P is what current silicon can do. Tetris is NP-complete. Chess is EXP-complete. MIT 6.006 Introduction to Algorithms, Fall 2011.

This is what Farage and Reform want to happen here. Never forget that Brexit was the dry run for Trump. Both succeeded and just look at the mess that WE are all in, not them. If you ever wondered what you’d have done in 30’s Germany, well, you’re doing it.
