A hydrocephalic demo!
But I'd be totally in to a 10% increase in IQ in exchange to being able to eat 10% more sugar.
Two flipflops interconnected on one wafer. Two flipflops inteconnected on one PCB. Two flipflops interconnected with a cable between two PCBs. These are all "distributed". They're all subject e.g. to the CAP theorem. Sure, the probability of one flipflop failing on the same wafer is quite small. The probability of one flipflop failing on one PCB is slightly larger. But fundamentally all these systems are the same. If you have two computers on a network you can make the probability of failure (e.g. of the network) pretty small.
distribution of signals within smaller systems (microcontrollers, ASICs, FPGAs, etc) are all distributed systems. Ask anyone doing any kind of circuit design about distributing clocks and clock skew, etc.
