its really possible to top out on some of these things. once you're at the point where you're like 'I could try to do this professionally, but that would ruin the fun of it and its a really tough market'

plus, dont forget about the substantial benefits from cross-training

if you find something thats really your thing, thats great, but the goal is to interest and engage yourself. why is it that important to demand the time to to eek out that last 5%

its also possible to actually blow through a field. the scope of coding projects I can just spit out as rote are well past what anyone is willing to adopt. what would be the point of training any further. there's really a lot more to learn about machining.
