I dont't think it's intuition. There's a whole field of junk economics dedicated to telling us that your position in the economic class hierarchy determines the automatability of your job. In general it goes unquestioned. A vast amount of capital is also deployed based upon this assumption.

This is an example paper that, for instance, mathematically blurred the distinction between offshoring and automation:

There was another paper (that i cant find right now) that basically surveyed people about how creative they thought their job was and just assumed that creativity was inversely proportional to automatability.

Ironically I think a widespread belief in this myth helped, among other things, lead to the trucker shortage. Who wants to join a profession with a high barrier to entry that they believe will be automated soon?
