O'Reilly transformed into a learning platform a while back. They still publish books, which are great for going deep, but their selling point is that you get unlimited access to a good chunk of the tech publishers' books, videos, live events, etc., and it's all searchable. ChatGPT will give you specific answers if you know what to ask, but personally, I'd rather learn from the experts building it. It might seem spendy, but chances are your company already has an account and you just need to ask around for access or if you're indy, they usually have yearly promos. I think it's about what you'd typically spend monthly on books.
