The beginning of interplanetary humans. Fascinating and awesome.

Oh man - sure hope this is the beginning of the real space age.

What was with the questions at the end of his talk?! You could tell he was getting annoyed with the burning man type stories and ridiculous requests to be a business partner or get a kiss. Elon isn't going to be your friend... sorry Space Nerds.

Thats why i found a video without the questions. They were SOOOOOOO annoying and embarrassing. The ones i heard made me cringe. I tuned out after the first few.

Does the audio quality get better? So much reverb...

My concern is this : Imagine a global extinction event , lets say a repeat of the event that killed off the dinosaurs : a massive asteroid direct hit , instantly killing everything on roughly the same continent or general planetside , such an impact would punch a hole in the very tectonic plate it lands on and cause massive waves not just in water , but in the ground itself , waves of rock and earth surface taveling around the globe meeting on the far side of the impact and ricocheting back again . We are talking GLOBAL earthquakes off the scales, for YEARS after the impact as the tectonic plates are slowliy settling in, all this is followed by a thick cloud of ash from the impact, refueled by frequent vulcanic eruptions , this will block out most sunlight , so after the initial toasting , the few lucky survives of this pandemonium can look forward to hundreds of years of atomic winter. Sounds pretty fuckin bad.

But guess what : thats still better conditions for life than Mars. And Mars is goddamn paradise compared to the other planets around us. Anything outside our immediate neighbourhood ? Forget it , they are ATLEAST thousands of years travel away, making moving anything of note there unfeasable. We ARE a one planet species. Get used to it , take good care of this one , its all we got.

-Massive Waves
-Global earthquakes
-Frequent Volcanic Eruptions

How is Mars worse than this? And it sounds like a lot of the tech used for Mars could help if this ever happened to Earth. How is that a bad thing?

Well, to be fair, we don't have any real idea of the living conditions on planets in nearby systems that are roughly earth sized. We haven't been able to detect them until the last few years, and most of those are orbiting too close to the sun (because those are the easiest to detect), and getting any kind of real idea of their atmospheres is currently unavailable. There could be several systems with habitable planets within 30 ly, we just don't know yet. We are improving our capacity to detect these every year, so perhaps by the time we have colonized Mars, we should have a few viable extra-solar earthlike planetary candidates to send probes. Still would be another 50-100+ years after sending probes to receive back enough data to justify sending colonists. Hopefully by then our tech has matured enough to make it possible, and the war with Mars has settled down enough.

If interested in the horrors that was the Q&A, here's a sampling

or a funnier exurb2a take on it

No magnetosphere. That means along with no water or air, you have to live in a microwave on 'thaw'. Sounds pretty harsh to me.
Maybe we would be better off reversing global warming on Venus and terraforming it.
