I disagree with that statement. There is nothing inherently wrong with using computer to learn and if your personal goal is to learn it in lot of cases makes it much easier, whether to search for or visualise a piece of knowledge you're' learning.
The problem is frankly computer and now computer with LLM makes it easy to cheat.
The kid doesn't want to learn, the kid wants good grades so parent is happy with them, and the young adult wants to get the paper coz they were told that is required for good life. It's misalignment of incentives.
