I take your brain, add a couple more rules, and presto! It can perform any computation.
Ix = x
Kxy = x
Sxyz = xz(yz)
This brain is interesting. Basically you get a no for everything you ask, right?
You get whatever you assign 0 to. You can combine it with other simple building blocks like f(x) = ~x to do large calculations to answer more complicated questions.
