Also interesting to note that the hype came a while after the release of GPT-3 (the tweet was about a month after), and that many of the examples could have possibly been generated from GPT-2 (which didn't get as much hype). Put another way, you could show ppl GPT-2 examples from a year ago and claim they were from GPT-3, and I don't think many would know the difference.
I do think GPT-3 has shown improvement, and it's a step forward, but it probably tells more about how humans interpret rather than how AI might work. Wrote about it more in the link below:
