Most of the economy involves moving around physical things. Construction, transport, nursing and related health occupations (physiotherapy, home aid, etc.), retail and wholesale logistics. Manufacturing employs another chunk. Services for agriculture, fishing, mining also employ more people than are directly employed in those industries and are mostly to do with machines and equipment. Utilities.

Most of the rest is high-touch. People want interactions with humans for important stuff, not with AI. Remote teaching was an unmitigated disaster for most school students: how will AI teachers do, do you think? Attempts at robot police and security guards haven't gone down very well to date. It'll be a while before there are AI EMTs and firemen.

So there are grounds for skepticism.
