Compilers don’t do this error free of course BUT if we want them too we can say what it means for a compiler to be correct very directly _one time_ and have it be done for all programs (see the definition for simulation in the CompCert compiler). This is a major and meaningful difference from AI which would need such a specification for each individual application you ask it to build because there is no general specification for correct translation from English to Code.
