Thank goodness. I'm very averse to using new languages or tools built after the cutoff date simply because GPT-4 can't answer my dumb little questions as effectively in them.
I'm not saying there isn't a place for traditional learning -- it's still important. But ChatGPT is an absolutely massive boost to productivity when you're only dipping your toes into something new.
Old tech has its place, but I can get e.g a caddyfile that works for me quicker with ChatGPT than in any other way.
