I used Wolfram Alpha a lot while I was in college and liked it a lot. So I am surprised to see the hatred toward this man in the comments. Can anyone enlighten me why he is delusional and why he has lost it?
There are two Stephen Wolframs: the one who makes useful software (Mathematica, Wolfram Alpha), and the one who fancies himself an academic. His success in the former lets him avoid humility in the latter, and this conflict is where the problems come in.
This multi computational idea seems to draw from the double slit experiment where observation collapses the wave function and the multi-probability path history based on the observer. This is saying that computations can be modeled similarly. And this type of model handles non-determinism in general and "threads of time" apparently. Interesting. Ambitious but very interesting.
