Biological meat doesn’t have the needed properties but this is how SpaceX and others avionics control works. Inputs are processed in discrete frames, all computers receive a frame of [last output | sensor_inputs], and implement a function where output = f(frame) : the output depends only on the frame input and all internal state is identical between the 3 computers.
Then, after processing, last_output=majority(output1, output2, output_n)
So even when one of the computers makes a transient fault, it can contribute to the next frame.
Current neural network based systems can be architected to work this way.
The computers are not identical but if your only information about them is their outputs they are indistinguishable from each other.
