I think after they have failed in space now is the time to waste more money to dig the ground, well I suppose those billions of dollars should be spent somehow you agree?
Also many countries still haven't yet completely managed to build their metro, but maybe he can enjoy driving in tunnels with 200KM/s.
What kind of failure they lost in space? Recently I heard that they made a good start. They put into orbit a reconnaissance satellite and the main stage of the rocket returned. It seems to me that you have incorrect information.
Space is no joke, a private company is small to take such matters in hand, we have more concerning matters here on earth that needs fixing asap.
IMAO we need to tackle any space related missions united as a whole, all countries and all the scientific and engineering minds should engage with space missions.
For the best and fastest results possible there needs to be at least $10 trillions, a few billion dollars is not enough and just wasting time and money.
Imagine what we have achieved if 200 countries worked together as one body.
