I don't think you fully appreciate the number of obstacles in the way of new entrants building commerically-operable airplanes. Flying a supersonic prototype is amazing. But it is a depressingly-small amount of the overall work necessary to simply start taking passengers, much less make something economical, and even less to make something succeed.
Yes, I'm fully aware the market for building commercial jets is probably one of the most locked-down on the planet.
But hard things have been done before. Throwing rocks at the people trying doesn't do much to help them. They're fully aware of the reasons they might fail.
Would you rather these folks just not try at all, so you don't have to feel jealous if they actually succeed?
I hope they succeed! It’s not throwing rocks at them to point out the obscene numbers of and size of obstacles they need to overcome to others on the sidelines who seem to think that this is anything more than a very, very early step along the way of a still-unlikely future product.
