Private companies will never save us. They exist only to extract wealth. SpaceX is no exception, surviving off of taxpayer funds.
Private money is perfect to make the same cheaper. Then consultants bring the knowledge to other companies. 20-50 years and everything is a commodity.
After some time in kind of free markets the common people win.
Any time now!
It's a very elegant idea, but maybe not the most empirically robust.
We've all been waiting. For more than 100 years. Private companies will save us... like we'll have Linux on the Desktop.
Any year, now.
