It astonishes me that people can dismiss ChatGPT like this. By your own account, there now exists an AI that can convincingly imitate a literate, technically fluent human child. That's an incredible advance that's far beyond anything that existed even a couple of years ago. How is it not amazing?
I get the sense that if some of the commenters here had been around to witness the Wright Brothers' first flight they'd have been like "meh, that's not impressive, the only people whose mind it will blow are people who've never been in a hot air balloon."
