You can also take the opposite conclusion from this: C++ is now viable because LLMs can catch the security bugs.

I'm obviously not entirely serious here, but I think this is true to some extent: the number of memory safety bugs in a codebase is finite. Once you have a way to find them, you can drive that number down to zero.

C++ has become a far safer language thanks to LLMs - at least if you run the LLMs before you are attacked.
