Broken Glass

Apparently Google has banned face recognition software from their "Glass" wearable computer, the one that looks like a pair of eyeglasses.
I wonder why.
Glass would be really useful if it would prompt you with a name when you meet some one.  About a zillion times I meet some one whose face I recognize but I cannot for the life of me, remember their name.  If Glass could recognize the same face and look up the name, it would be a killer app.
