I think the adult sons who unironically dream of colonising other planets (although no suitable candidate has been discovered thus far) are comfortable spouting this nonsense because they feel they will remain insulated from the effects of climate change 20 or 50 years from now (as they are right now) and they are too misanthropic to consider people losing lives and livelihoods to it right now as legitimate problems.

That's why these adult sons are comfortable having conversations about space stations and stuff as one of them puts it while the top scientists and engineers in US and China struggle to send like 5 people to the moon and back. If you bring up Musk you must be deranged despite the fact that he is an outspoken fascist deeply coupled with American space endeavours. Please let the adult sons talk about space stations and stuff completely disentangled from political and economic realities in discussions that would have been dated twenty years ago.
