Marx did not believe in the elimination of most physical labor through technological advancements alone in a capitalist society, because he believed capitalism contained within it certain tendencies which countered increasing automation and prevented it from developing beyond a limited point, so that manual industrial labor could not be eliminated until the overthrow of capitalism.[29] Some commentators on Marx have argued that at the time he wrote the Grundrisse, he thought that the collapse of capitalism due to advancing automation was inevitable despite these counter-tendencies, but that by the time of his major work Capital: Critique of Political Economy he had abandoned this view, and came to believe that capitalism could continually renew itself unless overthrown.[30][31][32]
