We are a long way from AI agents escaping air-gapped computers, let's worry about that when it's an actual problem and when the companies running thousands of agents are acting responsibly.
There are classes of problems that should be worried about aforehand, just ask the crew of the Titan.
Autonomous super intelligence escaping airgapped computers seems like one of those problems.
If they genuinely believe these models are going to obliterate the human race their utterly cavalier attitudes is be grounds for immediate government shutdown/takeover and arrest of everyone involved. If this was nuclear or biological research work none of this would be tolerated.
Set the right incentives at the top, and you will soon see that changes are made very quickly ... especially those 'industry leaders' previously called 'impossible to contain' or 'non-competitive' BS.
If everyone has to play by the same rules, and the rules are made for the good of society, then there is a true win-win - and not just a wealth transfer to the top and putting expensive damages on the general population.
On the plus side this requires collaboration both from the inside (on the airgap side) and the outside.
If you install a computer that's not running AI and it's airgapped, it won't suddenly start emitting radio waves out of nowhere.
We should not fall, once again, for the following logical fallacy: "Under exceptionally crazy circumstances it's possible to use RAM or the power line to exfiltrate data from a compliant airgapped computer, hence airgapping computers is pointless".
Can’t leak secrets if you don’t have RAM.
