Interesting stuff with this one and several notable absences... the wheel, television, airplane, camera, nail, concrete, steel, and not a single spot for medical breakthroughs like penicillin or antibiotics, or things like DNA and pasteurization? Some of this probably comes down to what qualifies as an invention (computer) vs. a discovery (fire).
Interested to hear what others think, particularly the engineering minds.
