Certificate revocation as an act of war... the 2030s are gonna be wild.

I'm reminded of Vernor Vinge's novel Rainbows End, which is set in 2025. It features a cyberattack against a rogue AI, which involves revoking a root CA certificate belonging to Credit Suisse, causing massive collateral damage to the European economy and infrastructure.

Vinge didn't quite get to see his rogue AI prediction become (sort of) reality, right on schedule, but he did at least outlive Credit Suisse.

It's already happening, you cannot access the websites of many sanctioned Russian entities without trusting a Russia-issued root CA. The fragmentation of the Internet is already in motion
