What is striking about Mythos isn't Mythos, it's that Mythos found exploits that really have no business existing. While it's generally understood there are bugs "in the wild," the type Mythos is finding are unusually severe. And they claim there are thousands in every major OS and web browser. It's also unusual that Google is endorsing Mythos, which is a competitor model. Even if Antropic is just running a hype train, why would Google throw its towel in to promote Antropic's model?
I think the project is called "glasswing" because it implies the airplane of society is flying with glass wings. Now, what we hope is that this is just a result of years of memory unsafe languages like C. But a more uncomfortable prospect is that in principle, attack surfaces may scale fundamentally faster than the ability to defend. This would mean in a Mythos-vs-Mythos match, the defending Mythos may always lose.
This starts to sound like a "great filter" scenario that had never crossed my mind. It may be that any civilization advanced enough to require general-purpose computing inherits an attack surface that scales faster than the ability to defend. Always. This would mean the moment the average device can run a Mythos-class model, any one person can launch devastating cyberattacks that cannot be defended against successfully. I know the "great filter" was once proposed to happen when any one member of a civilization can end it, but I always assumed that would require far-future technology. I hadn't thought about it being due to a mathematical quirk in how program state-spaces scale.
Of course I'm purely speculating. It's also rather plausible that memory safe languages and designs can constrain the attack surface. But it's also possible that "safe" languages really just push the attack surface slightly beyond the human attention span. If that's the case, Glasswing is a doomed Hail Mary.
