Air-gap AI channel moves 1–8 bits hourly

A viral AI-safety debate revived a 2015 BitWhisper demonstration whose tested air-gap channel carried roughly 1–8 bits per hour, according to TechCrunch’s review of the claim; Ben-Gurion University’s original research summary describes it as a proof of concept for communication across an air gap. That rate is a research-bound signal, not evidence that today’s agents can escape a properly isolated environment. Builders should test network and credential containment against real failure paths while keeping cinematic air-gap scenarios in proportion to the evidence; the archive’s evaluation-budget analysis makes the same case for evidence over safety theater.
