What they are promising to achieve is simply impossible to do. It assumes you could do logical and mathematical inferrence at the level of a Ph.D student...
... oh wait. I'm actually the one who wrote a review of Mathematica for MacWorld 15 years ago and said that it can reason to a level as good as a Ph.D student.
My opinion: there is about one person on earth who can pull this off, and this is the team. So I have great expectations.
