Anything requiring physical presence/action, since you said "AI", not "AI plus robotics".<p>For anything in the top ~1% of the human social ladder - you can count on the politicians, plutocrats, etc. who make the rules in human society being <i>extremely</i> reluctant to allow AI's to start replacing their own kind.<p>Your "can't ever" is too ambiguous. If "ever" allows thousands of years, then it's purely a philosophical/linguistic question. If you're mostly interested in credible threats to your own career, then it's more a technology/society question.
