The sign of true subject matter expert is someone who has the confidence to say when they don’t know the answer.

    input(“ask me any question”)
    print(“I don’t know”)

behold, Plato’s PhD level expert on any topic.

It’s missing the line for “if I don’t know the answer”

[jodrellblank]

It always doesn't know the answer, there's no branching possible, so no need for a branch test. By your definition that makes it a "true subject matter expert" on every subject. Although if you squint a bit, it does look rather like a plucked chicken.

Yes, but that better not be all the time, and around basic questions.

Sounds more like the sign of just a humble, honest person
