ULA has contracted Blue Origin for their BE-4 engine to power their Vulcan. Future heavy lift launches will fund Blue Origin for a bit.
Competition, good.
Living in space, colonizing Mars, mining asteroids, neurotic billionaires... Whatever. Just infotainment.
I agree about the living in space and colonizing mars which are mostly pipe dreams (that I'm admittedly optimistic about as a spaceflight enthusiast), but I think mining asteroids is a feasible proposition. The material is there, and in-situ resource extraction and return has been demonstrated. It's really just a matter of scale-up and putting in the upfront investment.
I don't really see how the Vulcan will be competitive with the existing launch capabilities of SpaceX, even if it does launch successfully before Starship.
I don't see how Blue Origin producing the engines for an also ran rocket is going to fund their operations. Blue Origin will be dependent of Bezos and the USG for quite a while, atleast until the New Glen can be launched re-usable.
