Returning to a technology largely discarded since the 1960s, scientists are betting on analog computing to wean AI systems off the monstrous amounts of electricity they currently require.

Why it matters: AI is on track to use up a tenth of the world's electricity by 2025, by one estimate. Cutting back on this consumption has huge climate implications — plus it’s essential for mobile devices and autonomous cars to do complex calculations on the fly.

Ford and Microsoft try to tackle traffic jams with quantum research

Ford and Microsoft have figured out how to leverage quantum computing — the powerful but not yet commercialized technology — to tackle traffic in Seattle.

Why it matters: By running quantum-inspired algorithms on conventional computer hardware, companies can process more data, giving them a head start on solving complex problems like how to direct thousands of vehicles simultaneously to smooth traffic flow.
