I dare you to find a single expert that would say that the advance of AI will have no impact on the job market in the future. That's a preposterous claim.
You yourself admit that AI acts as an assistant - well, is that assistant efficient? Can it help a person process more work in the same time? If so, the more efficient that "assistant" is, the fewer people you need to do the same amount of work, meaning some of them are no longer needed. It's not hard to grasp, is it?
Most likely yes, because at the moment we do not know all the possibilities that AI will be able to own, after a while, when it will improve. All this should lead to an improvement in the quality of human life, but at the initial stages it can deprive many jobs. At one time, the mechanization of production processes also led to the fact that robots replaced people and were able to work more, and people lost their jobs.
