That's not correct. You haven't lost your ability of anything that's physical by any of the inventions. People still carry a lot of load on their backs where wheels don't go. Also, if we don't "carry things" like the past, we developed gyms and buy dumbell to pull up weights. Don't we still do it?

Inventions making physical activity easier does not disappear our physical activity, but AI might cripple or completely paralyse human power of reasoning/thinking.
