Something I learned: K.I.S.S. is the most important principle in technology, but keeping technology simple while still adding value and utility is really hard.

Something I learned: K.I.S.S. is the most important principle in technology, but keeping technology simple while still adding value and utility is really hard. Example: how can we improve on the design of the bicycle, but keep it simple? You could add expensive composite materials, design a new gearing mechanism, create new complex geometries based on wind tunnel experiments... all of those are more advanced, but complex; simple is a tough nut to crack.
