Bezos thinks he can do the same in less than 6 years ?
What are you talking about? Blue Origin was originally founded to go after the Ansari X prize, by 2022 it will be TWENTY TWO YEARS OLD. IT IS OLDER THAN SPACEX!!!
It is just being done the Bezos way - methodically and making sure that every component can stand on its own and be a product. Its engines are already sold to ULA, other components are also likely to be available on a wholesale or "as a service" package.
It is slower, it takes more time than building a vertical like SpaceX, but it gets you there too in the end. It is also pretty much guaranteed to return investment even if it does not put anything into orbit. The engine sales alone will take care of that.
In any case, I would not be surprised if they put a satellite in orbit in 2022. On schedule. As intended.
