Some of these were built, other ideas just don't scale.
But most of these? They exist now. Not quite as nice as the video shows, but they exist.
Kinect actually enabled a lot of the voice control experiences, Skydrive and Sharepoint do some of the other sharing scenarios, just not as nice as they all should be. I saw some awesome mapping stuff working on Windows Mobile well before the iPhone came out, including actual building maps and linking into ones "social network" (however limited that was at that time) to show where one's friends sat.
It is actually sort of sad that none of the experiences have been polished nearly as well as they should have been, by any of the players in the market really. Google Hangouts comes close with some of their collaborative tools, but then something falls apart in the experience, for example in the case of Hangouts, it can be a pain to start one depending on which UI path ones chooses to take, and various bugs pop up and just break the immersion of the experience.
MSN Messenger had a lot of good stuff, video and voice conferencing both worked long ago, but then that market fell apart.
Collaborative Document Editing was done right by Microsoft with One Note 2007, and then completely ignored from then on by the rest of the Office line. Amazing technology, not sure why it wasn't more widely adopted (I'm guessing due to file format needs, presumably the One Note team had the advantage of building up from scratch).
Perhaps most amusing in this video is what people thought LCD screens would look like! I am thankful the ID on LCDs did not go that way!
