3:23:17x1bzzr handmade_hero I've heard you say before that you don't believe it's good or necessary to know many programming languages because, in your words, "programming works from first principles". I do hear all the time, though, that you shouldn't be married to a programming language and you should always use the best language for the problem you're trying to solve. Why do you think people think this way and can you elaborate on why you disagree?

3:32:46x1bzzr Q: Following up on the question about programming languages. A lot of people seem to think that dynamic languages are way more expressive than non-dynamic ones in the sense that you can accomplish a lot with very little code. When you say these languages are limited do you mostly mean they don't allow you to write performant code or do you mean more than that?
