I also only read the abstract.

The argument seems to be: Belief in God implies a belief in the fallibility of humans, which leads to a reduced reliance on humans and therefore increased willingness to accept AI recommendations.

Most of the logic in that argument checks out. I just don't understand the last step in the logic. How do decreased reliance on humans lead to increased willingness to accept AI?

I'm a religious person myself, and my argument would be to not trust AI all that much. It is a creation by fallible human beings trained on fallible human data.
