What does it mean for a thing to be hard to do in the context of different programming languages?

Hard and easy here are extremely deep and complex subject matters. Is goto hard or easy, for example?

The person is going to give up (or you are,) because you are not going to be able to just have this conversation for any meaningful length of time. This is a (bad) fantasy, and one that books sometimes attempt (that I hate) and some people fantasise this way.

They are not going to Ask The Next Question because if they could do that, it would come from a position of already understanding in a sort of anachronistic way. (In that they already have your answer, yet still want it.)

They lack intuition for all the new concepts, they have a bunch of false friends (to borrow from linguistics, in that they think they understand some of the concepts - but they are different concepts with the same or simliar names).

If you are a good teacher, then I am sure you will be very successful in explaining, but it's just not happening quickly nor with just anyone.
