The issue for now is LLM generation of code, not code auditing.
And no, I don't give a fuck whether some genius in theory could paint s new Mona Lisa with it. The issue us how it is used in practice, most of the time, today. At $WORK, I have a severely ai-pilled Senior Embedded Software Architect which hasnt managed in one and a half year to set up a working driver for a RS232-controlled stepper motor, from a port of previously working code. A thing that should take a week at most. I had to educate him that in C++ drivers, you need to use locks or mutexes to access variables that are concurrently changed and read from several threads. AI enables catastrophic levels of incompetence.
And FOSS projects need to protect themselves against that.
