I have never been the former, so I don't know how it works. That type of developer clearly must exist somewhere, because I hear people on HN talk about it, but I have always been a "hey, we have this interesting problem to solve, can you help" type of software developer. And yet, I have managed to stay quite good at this even without dedicating four hours of non-work time to it. To each their own.
