A good test is to try to port significant from c++ to plain and simple C using "AI". Maybe it can retain some of the semantics for the original code.
There is a more brutal option: AI could help write a c++ to plain and simple C transpiler... then we would lose the semantics of the original program, but free ourself from the very few toxic and real-life c++ compilers out there.
