In the same way that when the car got going, people thought it would be an electric car, people thought it would be a steam car. Actually, the dark horse in that race was internal combustion, but because of the energy density of gasoline and discovery of oil in large amounts at that point in first Pennsylvania and then Texas, it won out over those other two, to the point that those other two are actually viewed as obscure footnotes in history.

A lot of people assume that creating software is purely a solitary activity where you sit in an office with the door closed all day and write lots of code.

In energy, you have to plan and do research way in advance, sometimes decades in advance to get a new system that's safer, doesn't require us to go around the world to get all our oil.

Software is definitely engineering. It's different in that we take on novel tasks every time. It's not like building a certain bridge that is virtually identical to some previous bridge or some previous building.
