@jonmsterling As much as I mock blockchain as the most pointless technology ever devised, I tell folks: “if you absolutely love blockchain, do blockchain.” Just don’t do it because you think it’s “lucrative.” I promise you, you don’t know what’s lucrative. You’re a CS major, for Turing’s sake.
Learn something on a breath of topics. Go deeper than is reasonable on a few that interest you. That’s the only advice that I’ve seen work out again and again.
