Same with me. Made me also learn a lot of bash and Linux. I'm not expert (better than average but I'm not fucking around with kernels or deep stuff) and have found that very beneficial to my career, even (especially!) with agents.

Even if I ended up moving to something not hand written the learning helped me find which tools are actually the tools I want to use. Helps me reason about what's necessary.

I fully believe you can't reason about things unless you have some understanding beyond the minimum needed to reason about them. Otherwise you just have unknown unknowns.
