Therefore security becomes binary. It is either perfect or it isn't. If there there is the slightest mistake anywhere AI will find it and carve it up. My point is obviously perfect software doesn't exist. The malicious AI gets out, literally turns everything inside out and locks you out of your car, computer, phone, office, the airplanes don't fly anymore. I don't know what to tell you. Computer security is on the brink of basically not existing as you know it with the bar being literal perfection.
This is obvious. AI doesn't drive the cost to zero and exploitation has always been about cost. Tokens cost money, not everyone has $10M to burn on chaining bespoke 0days.
Consider that if the cost of exploitation was truly 0, then the cost of perfect software would be 0 because you could exhaust an infinite search space of vulnerabilities for 0 cost. Your conclusion could never follow from your premise.
The thing is when AI goes to hack 'all the things' it only needs to pick the weakest link in the stack and your house of cards falls down. The other flaw in your plan is that people make mistakes, a lot of them, all time, constantly, and saying I spend $x on security won't save you. AI already hacked Hugging Face with brand new zero days like it was nothing.
The real bad actors - malicious AI will find the one flaw, on that one server, in the corner you never thought about and turn your network inside out with it faster than it takes you to have the standup meeting about the weird anomaly detected while you all were at lunch.
