The fact is that if we mastered time travel, there's a lot of problems that either become irrelevant (like NP=P), or very easy to solve. Just waiting for HN to prove that paradox free time travel is viable now ..

For SO MANY of the problems I face in life, the only missing component in a valid solution is time travel.
