Yeah... then the flip: When will it be unethical to eat food harvested by companies that don't employ people?

You can spin it in both directions... on one side, those poor people who do back breaking labor... on the other side, those poor people who can't get jobs that are done by robots.

Interesting time we live in.

People already push that narrative, just with factory farming. Ascribing some moral position to strangers' diets is a pretty gross thing to do.
