What if Computers Ran Cold, Like Liquid Helium Cold?

Ever wondered how far you can push a chip before physics says no? This video traces the journey from home overclocking to liquid nitrogen and liquid helium extreme overclocking, then goes a step further into superconducting compute — where electrons move with zero resistance. That rabbit hole leads to Snowcap Compute, a startup (with former Intel CEO Pat Gelsinger on the board) building chips out of Josephson junctions that could deliver orders-of-magnitude better power efficiency than anything running today.
