Depends how they use them as arguably was the case with stack overflow or other resources in the past. E.g. an LLM can be a valid and useful way to start discovering or understanding code and architecture. You can ask for a summary , distill important concepts and then read in more detail about them.

Ya, this is the issue. LLMs are not great for developing minds. A lot like the internet presently, to be frank.

For fully developed and experienced minds, both can be useful.
