Unconventional Computing
summary
Moore scaling slows and fabs cost about $14 billion fabs, so alternatives appear: light, chemistry, DNA, living matter and quantum. IBM ships an experimental IBM photonic chip that routes computation with photons; chemical Belousov–Zhabotinsky waves implement sustained logic; DNA techniques solve small instances of the traveling‑salesman; a slime mold physically finds minimal paths and is used to redesign US highways; swarming crabs implement crab-based logic gates; quantum devices need millikelvin cryogenics and likely remain special‑purpose rather than general CPUs.
