You are correct, yet I don't see the connection between your reply and the comment you replied to? Nor even to the parent-parent comment. I'm baffled. Similarly for maxerickson's comment here. "Living" is about using resources, if "saving" them is the goal a dead planet is the best solution, or at least removal of all consumers of the resource in question. I don't see any "robot vs. worker" component in that statement.
