But that is work in the sense of energy, if robots are being used for production.

EDIT: Changed phrasing, to not distract from the actual argument.

If there is a comparison that is unfair, it's the one you just made between physical and mental work.

The people benefiting from this scam are not the ones doing the actual physical work.

I could say the same thing about webapps and mental work.
