Compared to human labor in 2023. e.g. if 50% of people get automated but then find new harder physical jobs that AI still can't do, this resolves YES.

Anything that revolves around interacting with the physical world and moving objects counts as a "physical job", even if it doesn't require actual muscle work. e.g. driving is a physical job.
