So far I think I have learned far more from LLMs than I've lost to them. I forget some syntax, definitely. But I now reach for a much wider range of tools that I have become familiar with because of LLMs. So, partly agree, partly disagree.
(Not to say that the current state of the art with LLMs merits borrowing money for a multi-trillion spend on hardware that will be obsolete in 5 years, but for me that is a different issue).
The master decrying the invention that resulted in more wisdom for more people than anything prior:
"For this invention will produce forgetfulness in the minds of those who learn to use it, because they will not practice their memory. Their trust in writing, produced by external characters which are no part of themselves, will discourage the use of their own memory within them. You have invented an elixir not of memory, but of reminding; and you offer your pupils the appearance of wisdom, not true wisdom, for they will read many things without instruction and will therefore seem [275b] to know many things, when they are for the most part ignorant and hard to get along with, since they are not wise, but only appear wise."
