Let me make a start - and others can weigh in... I guess, that's my first point - a 'good' answer requires more nuance than the question provides. We're only a short evolutionary distance from our hunter-gatherer past, learning is still social, even 'academic' learning - why else ask these things on HN? A little while ago,I was turned down for a training course - offered to all, our CEO said 'you could learn that from a book' - true, but; I wanted an on-ramp to an unfamiliar area (felt I didn't know what I didn't know). I think the bard scenario provides an alluring step forward but misses some of the complexity of learning (especially for this audience who have internalized it). Short answer, I think it's a useful idea, we (bard) is not there - yet - will be a useful research assistant, has a way to go before being a tutor, I'm not sure our (human) side would benefit from replacing good lecturers - the best I've known could steer my curiosity in a way (social) that I don't see emerging from LLMs - yet...
