dang is talking about "humans generating text which is 'better' than what ChatGPT can do."
Those are very different bars. Average output vs top output.
ChatGPT often generates text that a human might plausibly write. But is there text that a human could write that ChatGPT couldn't possibly write?
No, because ChatGPT is trained on text that humans wrote. Because what ChatGPT generates is based on what humans have wrote, it can always create the plausibility that a human might have created the text they are reading from it.
