> Knowing some folks that work on "major-browser-vendor" security in the era of Mythos-found-and-exploited vulnerabilities everywhere

Is this a thing now? I hadn't seen any big browser vulnerabilities recently. Did I miss something? Or are the vendors not releasing horrifying bugs they found internally with AI fuzzing?

It's never clear what's "real" vs. marketing for the LLM companies, but Mozilla at least has made a big deal publicly about the "unprecedented" number of "latent security bugs" they've found using tools like Mythos:

To be honest, I'm not sure how many (if any) of them have actually been exploited, but in any case, it seems like the cost to at least find a vulnerability anymore has really dropped dramatically.
