This is pure guesswork, I am not a security researcher, but my guess would be that AI is increasing the amount of low quality exploitable attack surface available, while simultaneously providing security researchers with an accelerant for their work. Which is to say, its great if you use it well and really bad if you use it poorly.
Not low quality if it works!
Those two things have almost nothing to do with one another. Lots of low quality things work they're still low quality.
The low quality refers to the features with security holes. So no, it didn't work (in this hypothetical).
But it is low quality if it's vulnerable to exploits. And if that's the case, I wouldn't say it really "works".
only until it's ransomware'd
