Breaking: turing-complete system can simulate any turing machine
How had I never seen this? This is brilliant!
Theoretically, anything that can implement boolean logic can be used to build a Turing-complete CPU. It just needs to represent a “true” state", a “false” state, a way to make a comparisons, and an input and output mechanism to feed other subunits or retrieve data from them. Stuff like this has also been implemented using water pumps/valves, and even in Minecraft using redstone. Computers don’t have to be based on electronics.
In short, everything that is Turing-conplete can compute anything.
Except for that which is non-computable.
Like yo Mama’s weight!

New to me that there is proof that something is not computable.
The most obvious answer to this is the halting problem.
That doesn’t compute.
Stuff like this has also been implemented using water pumps/valves, and even in Minecraft using redstone.
Or even in Minecraft using water pumps/valves
No! Bad boy! Very bad boy! Sit!
