If we were great at engineering, a century's worth would have ideally led to simpler machines. Simplicity = sophistication. (Before you hate on me, please know that I mean things should be as simple as possible, but no simpler. Cars, I believe, are not as simple as possible. They are incredibly complex. That said, look at a Tesla. Mechanically speaking, they're impressively simple machines.)
