ChatGPT is basically automated reversion to a slightly worse mean for applicable areas. The algos as sophisticated as they are produce a credible remix of the training input.
My analogy is that it is to writing what the spell checker is to spelling. Very few people in the world have to be good at spelling anymore. Yeah everyone is okay, but it's not as valued a skill as it used to be. ChatGPT is doing the same for writing. Yes you need to be able to write to an okay level but you don't need to be able to write well, ChatGPT does that.
