Merely choosing lines to copy and paste from one file of your own code to another is a learning experience for your brain. AI is excellent for removing a lot of grunt work, but that type of work also reinforces your brain even if you think you are learning nothing. Something can still be lost even if AI is merely providing templates or scaffolding. The same can be said of using Google to find examples, though. You should try to come up with the correct function name or parameter list yourself in your head before using a search engine or AI. And that is for the moist simple examples, e.g. "SQL table creation example". These should be things we know off the top of our heads, so we should first try to type it out before we go to look for an answer.
