No. It makes perfect sense. All economic activity is going to be intermediated digitally. Riches to those who get there first. Jeff Bezos saw this, and knew books were a good way to get his toe in the door. However, his aim was the railroad baron money all along.
When Amazon went from selling books to selling everything, people said it didn't make sense. Even I said that. However, in retrospect, it makes perfect sense.
(In the industrial revolution, people with far sight could predict that all economic activity would be intermediated through mechanized means of transportation. The analogy is perfect.)
