Your joke remind me a funny event occurring one year ago. I was chatting with an old friend working in the bank sector in Geneva. He asked me what's up today, I told him my interest in Smalltalk, he joked I was interested in computer archeology. It looked funny to me as well.
Your friend is right: we still use IT of the 70s... But maybe he's still using those of the late 60s himself (you know,{}, no boolean, source files, include files, preprocessor directives, compiler flags,...) That's something I usually answer.
