This sounds a bit too metaphysical to me. I can see why bot chess is not the same thing as human chess and we carry on with human tournaments, but why does anyone care if the compiler they're using is _not the same thing_? Like, clang is not the same as gcc, sure. Depending on the situation one may be better than the other.

Both the gcc and linux kernel have decades (centuries?) of knowledge between them, Mythos still finds buffer overflows and root exploits and much more.
