I'm not saying it's evidence for some larger trend; I'm presenting the reason why single-person teams might not advertise why they are single person and that these teams are not necessarily starting as single person teams, but sometimes collapsing down to single person teams.

Maybe you don't mean to, but when you present an anecdote you're implying evidence of some trend, otherwise it's just a pointless statement. And unless a multi-person team is collapsing down into multiple single person teams, there's no increase in productivity and we're actually in a worse position as a whole.

Except in context that was very much what was suggested. The implication of the comment I replied to is that there actually are "a ton of 1 person startups" (and by implication, that LLMs do enable the massive increases in productivity that their proponents like to claim), but that they just keep the fact that they are quiet.
