I assume you are in university. You have no obligation to assist this person if he isnt doing the basic work. Personally I would go it with the other guy - you dont want to get your grade lowered by someone who cant cut it. Its unfortunate that technology has passed him by, and its honorable that he is trying to catch up but its not your responsibility to teach him.

I would have given old balls more slack but once he starts lecturing you and talking down to you about talking about your generation then he gets no more slack IMO. Let him hang himself with his arrogance and fail the class.
