There could be some scenario where it is advantageous to have humans working with AI. But if that isn't how reality plays out then companies won't be able to afford to pay people.
LLMs act as interfaces to applications which you are capable to build yourself and run your own hardware, since you are much more capable.
It's going to be really fun for us people who love to write unicode symbols into numeric input boxes and such funny things.
We talk about AI replacing a workforce, but your observation that it's more about replacing applications is spot on. That's definitely going to be the trend, especially for traditional back-office processing.
An engineer shackled to an LLM has about 80% output.
The only argument we have so far is wild extrapolation and faith. The burden of proof is on the proclaimer.
