I'm throughly uninspired... As a friend of mine once said: "progress when you're going the wrong direction, is turning around".
The idea that we'll settle Mars while the Earth burns in borderline sinister. It reminds me of the elite outpost from Kingsman (the movie).
We have a planet that is in dire need of this kind of motivated action, and yet Elon would rather be distracted by this dream.
Don't get me wrong, I can appreciate the "cool" factor of expanding to other planets. I too enjoy a good science fiction story. Who wouldn't want to escape the problems we've inherited, and proliferated.
But escapism solves nothing for "us", and it's foolish to think Mars is anything else. If we as humans can't live on Earth responsibly, we frankly don't deserve to exist at all.
(Perhaps we should pull a Titan A.E., and preserve some DNA in the vast wasteland of space. Just in case an alien species decides to give us another go)
