It may be a mistake to ask which occupations are most safe from being taken by AI. What AI (in its current form) is good at is not so much certain jobs, but a certain way of working. It's good at scutwork. So that's the thing to avoid.

The most interesting consequence of this principle, though, is that it will become even more valuable to know what you're interested in. It's hard to do something really well if you're not deeply interested in it.
