The standard never has been and never will be absolute security. That’s an impossible threshold nothing would ever meet even though it’s objectively true that software today is generally more secure than software 30 years ago. The strongman claim being made is “Nix is harder and more expensive to exploit than traditional build systems”. So sure, if you find a cheap way to exploit Nix, track me down. But until then, it remains at least plausible & in practice very likely that Nix is harder to exploit than alternate systems on a technical level.
