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.)
