There is a long list of crazy ideas that businessmen took on, that became so successful everyone later thinks that those ideas were obvious.

Such as an internet phone. Like a personal computer. Like a Xerox copier. Like jet engines. Like a pencil with an eraser on the other end. Like interchangeable parts. Like the circular saw. Like electric power utilities.
