But second, I compared to the same level - I stopped at infrastructure. I didn’t consider the costs (energy or otherwise) of building a solar panel or power plants in the same way I didn’t consider the costs of a frying pan, a hob, or farms.

Which also uncomparable because like i said, we can forage and cook(or eat it raw) with no modern tools or money required, robot can’t forage sunlight without modern tech. Like you said, it’s a silly comparison that doesn’t make sense at all, which is what i trying to point out.
