Just responding to “[2] SpaceX has a valuation of just over $100 billion, and I haven’t seen a decent red-team from them on the viability of mars colonies vs. global bunkers. If you have links, please send them!” Seems like a bad waste of money to me.
Not SpaceX itself, or doing red-team analysis. It seems to me that establishing a self-sustaining mars colony to reduce existential risk is a bad waste of money (compared to eg establishing a self-sustaining Antarctica colony).

Martin Rees (the Astronomer Royal) has discussed this in a few books, most recently On the Future: Prospects for Humanity.
Thanks for the links!
To be clear, I assume you’re saying that SpaceX is a bad waste of money; not that red-team analyses would be bad wastes of money, right?
