The Power of Superconducting Logic and the Brain's Network Computation
40:18 - 46:30 (06:12)
The 90s introduced superconducting logic gates based on Josephson junctions for digital computing, while the brain's computation is based on a network of simple computers performing basic arithmetic operations.

Superconducting logic
Summary
Superconducting logic based on Josephson junctions was introduced in the 90s as an alternative to digital computing, but it may not be best suited for matching the capabilities of silicon-based technology. The circuit's limitations and the extent to which it can mimic the computations of the brain are still unclear.

Summary
Neurons in the brain fire asynchronously and build their own timescales, unlike digital systems which rely on clock cycles. The brain can be seen as a network of simple processors working together.
