User blog comment:Ygrain/EDI vs. Catalyst: now, who's the more advanced AI here?/@comment-5287758-20121211073656

Ahh yes, maybe, just maybe.......

The Catalyst has eons of experience of dealing with "annoying" "human" expressions. After all that, it has to assume the unfeeling, impassive, poker-faced, super-wise overlord.

EDI is a young, budding AI, far too "naive" to lose all her "humanity".
