The "too many security issues" meme feels like a form of product placement marketing. How many of the bugs found would have also been found if you said to a security team - ok you now have a project with independent time to go spelunking for bugs - this is your highest priority for the next month. Now do the same with a bunch of security teams across multiple organizations across the industry doing that at the same time. What is the differential in actuality with and without Mythos. The brilliant part is now those discoveries have a Anthropic mythos tag on them.
Even if it is marketing, at least there is some positive side effects of identified and closed security flaws.
