I don’t know if this necessarily follows. I repeatedly see that AI will write code, then you have it audit the code for security vulnerabilities, and it still finds them. Just because AI can find bugs doesn’t mean it will write bug-free code. AI’s know how to take shortcuts to achieve their goals, and do it all the time.

Yes, you can have another AI audit the first AI’s code, but in practice this doesn’t always happen, especially because once the human gets their hands on the finished product, they don’t always take the extra step to ensure it’s audited. This is particularly true because people seem to think “well the AI wrote it in the first place, why would it find its own bugs?”, ignoring that context is everything, and an AI being asked to find bugs is going to approach the code a lot differently than an AI tasked with adding features.

That’s not to say it’s not possible to set things up properly into multi-agent stages with QA and security as first-class phases of development… I only mean to say that it’s not automatically true that “AI can find bugs” implies “AI doesn’t produce bugs”.
