The same argument can be made for any other generation - the real engineering that happened back in the 70s for ARPANet was actually depending quite a lot on the generation before it (transistors, dielectric research, the ENIAC and computers that came long before them)...
My point still stands: every generation has incredibly difficult engineering challenges to overcome. Yes, it all builds on top of each generation, but there's no reason to denigrate the accomplishments of one generation or another.
