One, if cognitive overloading is not in the article, then it's good, it means I actually put some thought in the responding effort.
Two, AI expands possibilities for those that want that, and offer shortcuts for those that want that. No different from any other learning process: you could actually learn something or you could just do it. It makes sense, not all humans seek learning, but most humans look for results and answers.
Mastering a certain form of internet search does not mean you are learning, it means you are mastering, to some degree, a tool to search. Shortcuts are OK here, per me. Learning comes when you actually go beyond tool-use skills.
To be more explicit, the time learning a tool is not time used learning, it's time used preparing for learning. AI cuts that, if you want, and you get straight to actually learning something instead of tripping over tools and infrastructure, becoming too overloaded to be able to see the forest from the trees.
