There are environmental concerns, I get it, but this feels a little bit like delaying the Manhattan project for a year because the test detonation would endanger some birds in the desert.
Where's the outrage around the thousands of container ships that burn the dirtiest crude oil and dump their waste into the ocean? Or all the airliners killing birds?
Let's be real, this isn't environmental concerns, it's a way to punish Musk for his political stance.
Also - if our species doesn't make it off-planet before the current one is rendered uninhabitable, it's curtains for us all. So that's a pressure of a sort.
Columbus thought he could find a fast route to Asia because he grossly underestimated the circumference of the Earth. Spain was advised of this (the more correct circumference derived by Eratosthenes was commonly known), and only funded Columbus on the off chance that if he might stumble across something of value, they would rather that belong to Spain than a rival power. It was a cheap gamble for Spain at the time.
If you're wrong, but enough people believe you're right in the spirit of maximising quarterly returns, then we're all dead on the same timeline.
The only path to survival as a species is to work out how to do space exploration. I'm hoping to find water on the moon and mars as the next step, and to find it within the next few years.
Put differently: what's the strategic impact of a 2 month delay?
In a few decades at our current rate we're going to see so many natural disasters and mass migrations that the general populace will be far more concerned about food and water for the populace than wasting it on extravagances like space, and then we may end up all dying on this rock.
Once we're able to successfully mine minerals from space and have some hope for colonizing other planets the game changes, because people could see it as a lifeline rather than a waste.
