That pretty much describes my own behaviour. I still ask and answer questions on Meta - I’ve got a social connection here. But for learning about new programming languages and frameworks I rely on a combination of ChatGPT and online documentation.
Possibly the main thing LLMs have going for them is their availability. I’d prefer to get guidance from human experts, but no one has enough time or patience to answer all of my questions at the drop of a hat.
A big downside of learning through LLMs as opposed to learning on a public forum is that the information that is generated is private. It’s fairly seldom that learning something via an LLM is just a matter of asking it one question and having it return the correct answer. It’s more like ask it a question, try applying the answer, read some documentation to figure out why the answer didn’t work, get back to the LLM with a follow up question… eventually a bit of knowledge is generated.
I don’t think anyone wants to read other people’s chat logs, but possibly technical forums could promote the idea of people posting knowledge that they’ve gleaned from LLMs.
Another obvious downside of learning via LLMs is the loss of social connection, human attention as a motivation for learning, job opportunities, etc. That’s kind of a big deal from my point of view.
