What? No.

A real priest/minister/pastor/rabbi/imam is someone who... well, let's split this into two possibilities.

Possibility 1: God is actually there, and has told us real things about himself and how we are to relate to him. A real priest/minister/pastor/rabbi/imam has lived some of that, and can relate to you as you try to live it, and hopefully help you. In contrast, a robot can give you answers programmed into it by some Silicon Valley engineer.

Possibility 2: God is not actually there. All that spirituality is junk. The only thing religion has is, maybe, some wisdom in how to live well. As I'm trying to live life and run into challenges, a real priest/minister/pastor/rabbi/imam has still lived some of those challenges, and has some idea of how to live as a human being, and can maybe help me as I try to do so. A robot, on the other hand, give me answers programmed into it by some Silicon Valley engineer.

In both cases, the robot is less helpful, because it doesn't actually know what it's like to live. But it's worse if case 1 is true. It's still worse if I, the seeker (or whatever term) think that case 1 is true, because I'm just about dead certain that the robot hasn't lived the spirituality that it's trying to help guide me to.
