This is easy to refute.

Say a fraudster rips off 90% of what is in your checking account right now, you contact the bank and a language model tells you everything will be resolved shortly.

There is no reality now or in the future that this is good enough. Customer service is not just about getting the problem resolved, it is about having someone to blame when the resolution doesn't work.

If anything, I can picture a future that most knowledge work has some form of customer service involved, because that is exactly what can't be automated. A human that takes the blame/responsibility.
