But the businesses weren't profitable because they didn't have enough investment because they were run by an inventor, and the inventor couldn't promise how many he would sell in three years. I found out why Edison and Bell and Chester Carlson had so much trouble, and their ideas were more important than mine. Businesses have no use for real inventions or inventors because they don't want to deal with anything new. New things usually fail. Businesses want a slight variation on a successful theme.
Inventors are bored with that and the businessmen know it.
Inventors hear their own drummer - by definition. Businesses brag about and advertise for creativity and creative people. It's easy to be misled by that. Of course I mean intrinsic crummyness. Marketability is something else.
