The notion of an inventor is over-generalized in this article. There is a continuum of complexity in invention. If you invent clever, non-complex products like the Chop-o-matic, or the Sham-wow, then sure, sell it yourself. Hopefully this product concept came from a well identified, easily sellable customer problem to start with, and you became resourceful enough to engineer the thing because you already had a sales channel in mind. This makes you a resourceful salesman, and you better be because that is the only competitive advantage. However, if your invention is more complex, say an algorithm for linking pages together, or a peer-peer communication protocol, you had better find someone that actually knows how to commercialize technology. Because competitive advantage relies on being the best innovation or engineer, this version of inventor is solely focused on the innovation and invention of technology and needs to find the sales expertise elsewhere.
