This feels at first glance like another instance of an AI tool doing something humans already enjoy doing, rather than replacing work we'd like to avoid.

The teachers and professor I've known have always loved adapting their lessons to suit the interests of their students - I think that's a core educational instruction skill.

I'm open to hearing disagreements, but reading through the usages and evaluations does not leave me thinking of a tool that would provide any benefit greater than just giving teachers more resources would.

Also some stuff are just hard to learn. They require a good (even deep) familiarity with some foundational knowledge and it will be a slow process to go through those.
