He does have a point though. We all know manned spaced flight is possible and it's been done before. The stuff they're doing is cool from a technology perspective and is bringing down the cost of travelling to space. However, our planet is suffering from damage to the environment (pollution, running out of natural resources, piles of plastic waste im the sea and rivers, etc.). It would be good if a billionaire could get behind some of these environmental issues and make a difference so we don't totally ruin our home planet and require us to leave it at some point to find another planet to screw up. I know Amazon are making some efforts with planting trees, etc. but we need some technological innovation to tackle the other problems. How much pollution do these rocket launches cause? How much space pollution has Elon Musk caused with his huge consellation of micro-satellites to beam broadband from space? We can't keep lobbing more and more crap into space and letting it sit there forever.
I think it's good that they leaked that the Queen complained about political leaders saying one thing and doing another. That's one benefit old age brings. You can speak your mind and you don't really care what others think of what you say. I like straight talkers. They're so much easier to understand.
