> It's a pretty amazing accomplishment for humanity to have developed systems as complex as modern jumbo jets with "brains" that are essentially more reliable than the ones that created them. Airplanes are not reliable. That's why they require frequent and regular maintenance. Ignoring the poor analogy linking brains/humans to human built systems, if every human maintained their mental and physical health as much as airplanes get, then they'd all be much better off.
