I disagree with the bit about it being "high quality writing," virtually every example I've seen is word salad at worst and dialectical nonsense at best.

If your standard is "that looks like a sentence" then sure, it's largely okay. But if your standard is "communicates a concept" then we're still a long way off.

That's okay, because GPT can handle both writing and reading. We don't have to do either one any more!
