I felt like that for a while, but I seem to be finding new challenges again. Lately I've been deep-diving on data pipelines and embedded systems. Sometimes I find problems that are easy enough to solve by brute force, but elegant solutions are not obvious at all. It's a lot of fun.

It could be that you're way ahead of me and I'll wind up feeling like that again.
