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.

New to me that there is proof that something is not computable.

[–] [email protected] 17 points 9 months ago

The most obvious answer to this is the halting problem.

[–] Brickhead92 2 points 9 months ago

That doesn't compute.

On modern CPUs? Almost.
