It doesn't even threaten intellectual workers as it constantly makes mistakes and will generate solutions that look right but are actually very incorrect (which makes the errors much harder to find if you've fired all your intellectual workers).

What it can (and is currently) easily replace is simple middle management work, and simple clerical/recruitment work. Stuff like summarizing documents, writing copy, writing emails, responding to employment inquiry, etc.

The mass layoffs we saw earlier this year from the tech giants weren't programmers or engineers, it was all middle managers and recruiters.
