I watched the whole thing and like the philosophy of the approach. Unfortunately there isn't a single demonstration of the software, nor a direct comparison between the software and other machine learning algorithms.
At one point Hawkins even says he's not going to waste time by talking about specific data sets they've applied the software to because there are too many! Then pick one! Pick the best!
In the presentation it was mentioned they will release some software in 2011. He also mentioned there are papers + pseudo-code on the website for research purposes to play with. So for people really interested in it (and it does sound very interesting and promising), it should be possible to make those kind of demos/comparisons. Though I have to agree with you that one demo would have been nice.
