Honestly I'm just trying to be nice about it. I don't know that I can tell you a story about the 90% ceiling that makes any sense, especially since you can task 3 different high-caliber teams of senior software security people on an app and get 3 different (overlapping, but different) sets of vulnerabilities back. By the end of 2027, if you did a triangle test, 2:1 agents/humans or vice/versa, I don't think you'd be able to distinguish.
Just registering the prediction.
