30 Years on the Frontlines of the Internet: Why I’m Optimistic About AI

A Cisco executive draws on three decades of internet security experience to argue that AI should be treated as powerful software—not an alien force—and that the right combination of engineering, independent oversight, and institutional discipline can make AI safer while letting innovation proceed.

Useful takeaways from this story.

Adopt aviation-style practices for AI: independent monitoring, controlled operational trials, transparent investigations, and rules that apply across companies.

Security culture must accept humility: design systems that fail-safe, avoid relying on individual expertise, and treat investigation and shared learning as routine.

The useful part

Nobody knew it then, but he was fielding what would become one of the first cybersecurity service calls in the history of the commercial internet. We couldn't have predicted the scale or sophistication of the attacks that are now routine. We were focused on building something the world had never seen, and the people trying to break it hadn't caught up yet.

How it works

  • Powerful, fast-moving, occasionally unpredictable software, but software nonetheless, and we have done this before.
  • If a plane fails a preflight check, it doesn't fly, no matter how well it flew yesterday.
  • Every serious security practitioner I know carries a version of that humility — the quiet knowledge that your best work is invisible by design, and the one day it isn't, everyone will see it.
  • This is the fight our industry shows up for every single day, and it is a fight we do not always win.
  • We can't predict exactly where AI will create risk next — anyone who tells you they can is selling something.

What to take from it

Not because it will be easy, but because we have thirty years of hard-won muscle memory as an industry for exactly this kind of problem. That said, I want to be careful not to sound cavalier, because there are no victory laps in security. A system that is secure today can be vulnerable tomorrow, not because anyone made a mistake, but because the people on the other side are also innovating.

Example or evidence

  • That gap between what we build and what we can defend is not new, and it is not evidence of recklessness.
  • At the time, Cisco had been building internet infrastructure for a decade.
  • English (United States) (en-US) -- DEFAULT Microsoft Mark.

AI risks are real. So is human ingenuity.

AI safety deserves urgent leadership, serious investment and a place among our highest strategic priorities. Recent incidents justify growing concern I also believe in our capacity to investigate, invent and adapt. Meaningful human control must cover both the technology and the institutions deciding how it is developed
