Nobody forces you to stick to one kind of role. It's okay to try a couple of roles. I love (computer) science research and (software systems) development, so that's what I have been enjoying since age 11. Over three decades on, I'm a professor of artificial intelligence, which gives me maximum freedom to play around and invent new techniques. Among other things, I get paid to read HN, write papers and software, and teach the next generation some interesting topics like machine learning.
