Because it's really daft on a number of levels.

Firstly there's no evidence what so ever that the current generation of AI is a pathway to a general intelligence or anything god like.

Secondly it seems to me that most decisions are about preserving money and traditions and positions of power - faith in "God" is a different thing entirely and maybe the church wouldn't be so awful if they were focused on that.

Finally I don't really think the emergence of a man made god-tier intelligence would really challenge believers in "God". As in, I can see the connection logically but any Christian will tell you their belief is based on faith - it's not logical.
