It's funny that GP mentioned science fiction as a negative because what immediately springs to mind, for me, is Neal Stephenson's The Diamond Age. We literally have the tools to build his "Young Lady's Illustrated Primer" today. We just have to give today's AI a lesson plan to follow and ensure that it never gives the student the answers, and only keeps explaining the concepts in different ways until they click. Wrap that in an iPad app and you've essentially got the exact self-paced learning tool that Stephenson envisioned changing the world.

Its not teaching. These people cant pass a the class. They never went through the friction needed to learn

Social media wasn't always toxic at least not to the degree it is today. LLMs could be potentially a lot worse given the right set of instructions

They are great for self-teaching and great to cheat and not learn anything, depending on how you use them.

Main problem is that the technology was very disruptive for education and nobody has figured out yet how to utilize it at scale for schools and universities.
