My spouse is a university professor. A lot of her students cheat using AI. I am sure that they could be using AI as a learning mechanism, but they observably aren't. Now, the motivations for using AI to pass a class are different but I think that it is important to recognize that there is using AI to build something and learn and there is using AI to build something.

Engineering is also the process of development and maintenance over time. While an AI tool might help you build something that functions, that's just the first step.

I am sure that there are people who leverage AI in such a way that the build a thing and also ask it a lot of questions about why it is built in a certain way and seek to internalize that. I'd wager that this is a small minority.
