Fun story to read. Interested in the quibbles now.
My first quibble is that if you're used to a triple-omni God, the fellow in the story is a pathetic excuse. He dodges the question of whether he's God in his home universe. He has a lot of power, but he understands our universe on such a broad statistical level that he can't or won't use it in detail. The same goes for omnibenevolence, only more so.
I wouldn't mind growing up to be the likes of him, and thinking that one is more important than one is seems to be pretty common among humans and might be conserved, or claiming such might be an intelligence tes...
Talking with God is a pleasant and inspiring transhumanist short story. I've got some quibbles, but I'll save them for the comments because I think the story is better without spoilers.
