Exactly. I'm currently reading The Mythical Man-Month. 90% of what the book discusses in term of programming work that actually has to be done is completely irrelevant today. Still the software industry is bigger then ever. In the book it is also mentioned that programmers spend about 50% of their time on non-programming tasks. In my experience this is also true today. So no matter the tools we've got, the profession stayed the same since the early 70s.
