I don't care if the software can pass a Turing test or not. It's tough not to anthropomorphize here, but I would be happy if it could understand and be 'aware' of when I am busy, and divert calls or messages 'intuitively.' It would agregate behaviour
as Eric Horvitz said. I think the draw back in the selling of this is that your boss could hack your assistant - so to speak, and find out how productive you are. Or are not. And performance reviews could be contingent on your assistant's word you were working
or not. I would still like to see one in a couple of years when it is more widely available. Microsoft SideKick or Microsoft Gatekeeper have a nice ring to it. Perhaps Gateskeeper?
How many of the black cubes does Eric Horvitz have? It looked like a obsidian Rubic's cube farm on those shelves.
