It's essentially a pitch for the Wolfram Physics Project. How useful is it to work through a system which has some probability $p$ of modelling the basic nature of the universe to some degree $d$? Reasonable people may reasonably differ on the answer depending on $p$ and $d$, and on the values of $p$ and $d$ in any given instance.
