Nowadays I get paid to solve trivial problems, self-inflicted complexity, and work in problem domains I have no interest in. But it gets me a nice living.
Incidentally, I feel like this is why I gave up on running OpenWRT on my routers, or FreeNAS on my NAS, and why I don't end up sticking with Linux on my personal computers. I enjoy computing, but it's not my hobby. My hobbies are things that I do with my computer.
I think getting really pulpy, difficult problems is a rarity even at the top of the field. I don't think that should be the goal and particularly not most of your time (it would probably drive us insane)
What we can do is solve trivial (or easy) problems in ways that are elegant and robust and easy for other developers to understand. That in itself is a challenge.
