Gary Marcus jumps into Noam Brown airgap debate: DRAM EM leaks hit 300kbps
GaryMarcus · x · 2026-09-18
Gary Marcus quote-tweets deedydas with a jab at Noam Brown. The quoted post argues airgapped computers can communicate via temperature changes, but at a useless 1-8 bits/hour — while the security literature is full of faster exfiltration channels, like EM emanations from DRAM clocks reaching 300kbps. The point: with perfect knowledge of this literature, AI capabilities here are vastly underestimated. This isn't sci-fi.
