Just want to add some context. I'm not going to respond to the specific arguments here, but I want to clarify a few things:

• As I wrote in the original post, the app (that I vibecoded in 10min)'s sole purpose was to illustrate the concept of comparative advantage: "This doesn't cover wages, income tax implications, or other important things - it's only to explain comparative advantage." It was a quick sketch to explain a single economic principle, not a comprehensive thesis on AGI.
• Nor did I claim this was sufficient or all there is, which the post implies in places. CA has nothing to do with "keep[ing] the biosphere alive". Hopefully will make my views clearer in a future piece, as well as why I think the post gets some stuff wrong (including still misunderstanding CA). 

Also I'm not the 'lead on the Google DeepMind governance team' either.
