Having trouble accepting reality?
1. Spacex has only rearranged existing technology. The rocket engines are not new technology. Neither are the vehicle structures or avionics.
Which is suppose to mean what exactly? That it's impossible for SpaceX to succeed in putting a reusable booster into service? Hardly.
I think there's not that much totally new in any of Musk's businesses. Whether it's an electric car with laptop battery cells or vertical landing with relatively normal gas generator lox-kerosene rocket engines.
I think that's also a key to success. They're not exotic at all. We already have good technology, just need good execution on the assembly and the business.
That's it - vertical integration of manufacture, minimalise development costs with no new technologies - no plug nozzle, no wings, no LACE, no warp drive, no jacuzzi. Anything else has high risk and high expense needing to be amortised in launch costs, rendering the exercise futile. The dumbest bird that flies is worth a thousand powerpoint presentations.
I remember when Steve Jobs died some historians were getting huffy about comparisons with Edison (forgetting that Edison stole a lot of ideas and DIDN't work alone, but industrialised invention), saying that he never actually invented anything himself, which completely missed the point. Monet didn't invent paint either: the invention is in HOW it's done.
Elon Musk is an interesting fellow with a real long-term vision - he's opened up a lot of his patents actually helping his rivals and competitors in various fields (if you look at the news from recent motor shows, it seems every car manufacturer including the likes of Porsche and Aston Martin are showing off electric sports cars and SUVs with imminent production promised). More than making billions, he wants to leverage change in the world and I get the impression that nothing would delight him more than see someone else come along later with better technology. What he's doing now is breaking logjams and thereby opening new markets that will make the investment in better technologies worthwhile and compelling.
