Socrates wasn't wrong. Reading a lot gives you a partial understanding but it isn't complete without experiencing the thing for yourself. Arguably the Internet is the natural home of authoritatively stated but uninformed opinions - the exact result of reading a lot about a subject without having any experience of it.

I think the Phaedrus is all about the importance of practice. I've been reading a lot of math books lately, but I don't actually grok anything well until I sit down and try to reason through the material myself, write my own little proofs, try to deconstruct what's being said actively with pen and paper. Similarly, I understand a work of literature far more deeply if I take active notes, and/or write a small essay about my interpretation. I become a better writer by reading good writers and emulating them in my own writing practice. Writing was a threat to poets when the goal was still to recite a compelling live performance, which, to do this well, would require memorization and practice—today, still, we ask that actors do not have paper scripts in front of them when performing in a film.

This is kind of the threat that tools like LLM's pose. Their power to generate decent results means that far more people will eschew practice for "good enough" LLM produced results. Creation will become even more transactional, and (many) people will quickly fail to "see the point" in practicing until we have a culture that's degraded even further than it already has today.
