This episode made me think of Zegapain. If you've seen that show, you know what I mean.
I'm guessing that the typing on the keyboard is just the visual representation of what is actually happening to someone watching. SAO is a VRMMO, so Kirito was probably just thinking of what he wanted to do and having admin access for just a moment was enough to make it happen. It's still too convenient, like how The Matrix had an Explainer to Explain to Neo what was happening just when he needed things Explained. But I guess virtual worlds don't need to obey the laws of sensible plot moments, amirite?
Lucky for Asuna, she doesn't even have to experience the nine months of carrying a bowling ball strapped to her stomach and then the agonizing pain of childbirth to have a perfectly formed AI child!
