That tweet coins the term, we agree there. The activity it describes is using natural language to generate software. Whether you add a review process or not doesn't substantially change that. Sure, Karpathy says he doesn't "read the diffs anymore". Why does he say "anymore"? Clearly he was reading them at some point. If not reading any diffs was a core part of the activity, that wouldn't be the case, the tweet itself clearly outlines that as optional. He's clearly not talking about a core part of the activity.
