Is it possible that all real product ideas come from the mind of a single person, understanding and interacting with other people as actual people? And corporations are some sort of Thing that takes humanity and squishes it into a Box, a Box with one very narrow goal: to freeze the product idea from the single person and mass-produce it, "scale it up" so that millions of people are aware of its existence and are able to use it?
I mean, Google didn't even invent Google Docs. Some random little startup did. Google just bought it, then made it discoverable and usable to millions.
Which is not a small thing, I guess. But I don't know what the marketing department is for. Other than putting Google Docs on billboards, maybe, or their digital equivalent.
