Agreed, I'd add to the statement, "you're basically screwed, often, without investing a ton of time (e.g. weekends)"

Figuring out 'make' errors when I was bad at C on microcontrollers a decade ago? (still am) Careful pondering of possible meanings of words... trial and error tweaks of code and recompiling in hopes that I was just off by a tiny thing, but 2 hours later and 30 attempts later, and realizing I'd done a bad job of tracking what I'd tried and hadn't? Well, made me better at being careful at triaging issues. But it wasn't something I was enthusiastic to pick back up the next weekend, or for the next idea I had.

Revisiting that combination of hardware/code a decade later and having it go much faster with ChatGPT... that was fun.
