The demo isn't a virtual assistant. Its a glorified search engine with API integration and voice recognition.<p>My vision of a virtual assistant is that you would be able to say: "Book dinner with Ross and David next week", and the only other interactions you have with the agent are "You're going to that Indian you and Ross like on Tuesday at 7" or "Can't be done, how about Monday the week after?", and possibly a message when you use your calendar "Trying to book David and Ross for dinner this evening" on some days the assistant has picked out. Meanwhile, Ross and David get e-mails that appear to be from you in address, tone and content, suggesting dates and places. If they have assistants too, maybe they don't see them; if they don't, then they can reply and the assistant understands them.<p>That's the sort of thing a PA actually does; they don't Google the flights for you, they know your diary, your preferences and your needs and they book the right damn flight. Your phone should be saying "Walk out of your office at 2pm and get into the cab that'll be waiting. At the airport, walk to check-in desk 301 and hand me over. I'll take it from there."<p>The predictions, especially with regard to leveraging data in Facebook sound closer, so I'm waiting eagerly.
