Also unsure why you would go for CO2 in the atmosphere as a source of carbon rather than more low entropy, easily harvested ones (like fossil fuels, plastics, or, well, biomass).
Eliezer’s scenario uses atmospheric CHON. Also, I guess Eliezer used atmospheric CHON to allow the nanomachines to spread much more freely and aggressively.
