Very apt depiction!
Musk posits that AI will take over unless humans incorporate it into their own bodies and minds (basically saying that "if you can't lick 'em, join 'em). As an aside, I don't necessarily agree with him.
I don't think Musk is considering the religious implications one way or another. Neuralink is just a practical solution.
In fact, Musk's point is that we are already "part man-part machine" by virtue of our interaction with the technology developed in the last 100 years.
Our bodies don't have wings, but we have airports. We don't have mental implants (yet), but we have smartphones.
Exactly.
I, Robot.
