Bill, I have no problem with Musk (except for when I put on too much of it) seriously though, I don't see the logic of going to space in order to develop technology to save us from climate change when we should act like adults and make the commitment to cut out all the middlemen and develop it for it's own sake, from every thing I've read and seen time is of the essence. Have we got time to build a dome on Mars for people who can afford to live in it and use the resulting technolgy to "clean out the litter box". It seems like our priorities are terribly skewed. I'm sure I won't leave my grandson the price of a ticket. I know saving this planet is a daunting task but if we don't we really don't deserve to survive as z species. Now back to work.
