These models are definitely a lot better than your run of the mill human developer at finding security flaws in existing systems. I'm agnostic at how good they are at actually making a secure system. Probably better, too, for two reasons:

- humans are really terrible

- the model probably has an easier time picking up special purpose tools you can use to write proven secure systems

I don't think Mythos can write secure C code, either. Practically no one can. (At least not directly. See how seL4 is officially written in C; but they didn't just set out to carefully write secure C code directly; C just happens to be an intermediate language they use.)

Agreed. In the right hands, they can perform magic.
