Clearly, the author didn't even do the most basic fact checking. Since, Facebook clearly told everyone that M was going to be AI that was assisted by humans.
It's literally in the announcement post: https://www.facebook.com/Davemarcus/posts/10156070660595195

The AI can still do the requirements/information gathering and leaving the job for a person to do. For common issues (support triage, customer service issues) even this still has significant value.
Equally from a training point of view, it may simply be the person correcting/confirming the AI is right, and leaving it to get on with the process, rather than fallover to the human completely.
