I'm not quite 40 but starting to feel the effects of age, AI has been a great tool if not for the fact it saves my hands. I don't have it write the logic for me, mostly just stuff like smart autocomplete etc. I battle really severe tendonitis, I've noticed a definite improvement since I started using code complete.

As far as knowledge/experience, I worry about a day where "vibe coding" takes over the world and it's only the greybeards that have any clue WTF is going on. Probably profitable, but also sounds like a hellscape to me.

I would hate to be a junior right now.

I would love to be a junior right now. I would just hate becoming a senior, after having been a junior right now.

Well, whats the difference between Vibe Coding in 5 - 10 years vs coding in C 5 - 10 years after compilers came out?
