I find the unbridled optimism just unfathomable. Here's two examples of plain old jet programs, small jets at that: https://en.wikipedia.org/wiki/Mitsubishi_Regional_Jet 1.5 billion dollars. https://en.wikipedia.org/wiki/Bombardier_CSeries 5.4 billion dollars.

This is not a piece of software app that you can just launch whenever you feel ready full of bugs. You can't pull an Uber and say, hey fuck regulations, we will just do it (https://www.theguardian.com/technology/2016/dec/19/uber-self...). Yeah, sure, if you want to fly between Inner and Outer Camelstan then you might get away with the very fashionable "disrupt" shit but if you want to fly airspaces controlled by the FAA, EASA, CASA -- and let's face it, the money is in New York, London and Sydney -- then you need to do better.

This is going to cost 5-10 billion dollars at least just based on the very fact that the C Series costed 5B and I can't see what here would make it cheaper. And it's not easy to see how are you going to recuperate that much money, this is not a big market and while obviously time is money, it's a very big question of just how much money. Gulfstream delivers 140 planes a year https://www.wsj.com/articles/general-dynamics-profit-rises-9... with about 2-2.5b profit a year. I absolutely can not see how these numbers will stack up. Is this another venture capitalist fueled hype? VC invests, hypes it up, gets rid of the stock, small investors at the end get to hold the bag.
