'... top-level node compares the shapes against a library of objects and selects the best match ...'

Sounds a bit like cyc (http://www.cyc.com/cyc/technology/whatiscyc) with this statement. What objects are stored? Who decides what goes in the library? Wonder if they intend to use 'human' seeding of data to improve the system?

We don't know how much is wired in the brain when a person is born and how much he learns and how. Generally, I don't think imitating nature ever works. You can experiment this way forever.

This sounds like a marketing hit. Do revolutions need marketing?
