Why aren't there more human-language startups? ... languages have value substantially due to network effect. By making a proprietary language you hobble the network effect and destroy the language's value. And there aren't startups to create open languages because monetization is a big "then a miracle occurs"-- there is no obvious moat. And at our current level of science re-programmer productivity, it's a lemon market: lots of people say this or that will improve productivity but there aren't much in the way of established ways to prove it. Hard to convince people to pay for something when its benefits aren't unambiguous.
