I think that AI alone will not really take over any jobs. We currently only use it as you said, AI assistance. It has basically become a useful tool that helps us and makes the job easier. But the job still remains as is.

In the future when we have even newer technologies then perhaps a mix of those technologies will take over old jobs. But right now only humans are versatile enough to get any and all facets of a job done. That is not something AI can do.
