In karpathy's defense, this actually seems great. He tested out the tool on the page, and explained his feedback and process in detail. He was explicit in the followup comment about it. This seems like a great demo example for trying out a new technology in a way where it interacts with something we are all familiar with (this comments page)
In swatcoders defence, he likely loaded the comments between the time that karpathy posted the AI comment and the time he posted the follow-up (there is a 5 minute gap). The timings on the comments seem to suggest that possibility at least.
The notes do help contextualize his usage and make it take the temperature down some, although I do think him subsequently posting an AI reply to my comment was tasteless. (But I also get it. I used harsh words there and invited some ribbing in return.)
