> I'm not aware of any jobs where physical robustness is the primary job attribute.
Not really disagreeing with you, but there are a few obvious examples. A lot of construction jobs are still labour intensive, and I've seen a lot of people who don't last the first day, let alone their first week. Also, security jobs, say in nightclubs, also value physical robustness. Orderlies in hospital, require the ability to move bodies, alive and otherwise. The machine is usually better.
There are a lot of jobs where physical robustness is an important job attribute. That's not the same as saying it's the primary attribute, though. You aren't paying that construction worker to lift things, you're paying him to place things correctly--a skill computers still fare quite poorly at. Lifting is not the focus.
