Nothing on Moon Base Alpha except a picture. Would be nice to have a timeline for this (maybe the gap years where Mars transit is too long?)

I think this is a nod to ESA who has stated they want to build a base on the moon: http://www.esa.int/About_Us/Ministerial_Council_2016/Moon_Vi... Elon's message: "Here's the rocket, it costs this much, go build it". Basically trying to find more ways to monetize BFR.

Just like everybody else I'm really blown away by what SpaceX does, but at the same time I think the question begs to be asked: Has humanity already given up on earth as a home? Is the future really about planets as disposable habitats?

Considering how long it will take to get a proper bioshpere on Mars, which will only work IF we can teraform Mars properly, I dont think we'll be able to abandon Earth any time soon. I think the Mars colony will be something more like our base in Antarctica--a place for scientists, but not somewhere anyone would want to live permanently.

With increased technology comes more liberties for all. With your kind of thinking we would still live in caves because why work on anything unless we solve all our social issues first? Progress is not made by politicians, it is made by engineers. If you want clean water for all humans, you should be supportive of discovering new stuff.

I disagree, a lot of nations became stable because of engineering solutions in the first place and also more scientifically literate. There is a ton of examples of this. The first telescope, as an example, thanks to Hans Lippershey and Galileo Galilei showed that the earth wasn't flat and removed some power from the church it also clearly made us see that the sun doesn't go around the earth so it showed that Copernicus was right all along. A big discovery that made people doubt the christian religion and change the political landscape forever.

All big scientific discoveries changed the societies in a big way and there is no going back. Scientific discoveries and technological innovation is the only thing that push a society forward.

Loving this..Big visions, some may work, some not. Inspiring..Going against odds, this is what humanity should stand for. These are the real 'moonshots'.

Would love to see these kinds of big picture roadmaps in other areas/industries. It's a shame so much of our possible progress is politicised.

So the key takeaway for me today compared to 1 year ago, is that Elon has put a lot of thought on how to make this plan economically viable compared to just the vision last year. Multiple potential streams of revenue:

- Government/intragovernment contracts to cleanup space debris.

- Government/Private satellite launches.

- Earth to earth transportation which Elon announced on Instagram that the cost would be comparable to an economy fare. https://www.instagram.com/p/BZnVfWxgdLe/

- Transporting gear for ESA's moon base plan http://www.esa.int/About_Us/Ministerial_Council_2016/Moon_Vi....

- Transporting Government/Private equipment to Mars.

This is very much a realistic business approach compared to last year's vision presentation.

I would be really excited about a future where everyone had access to clean water. Going to space is fun and exciting. The future of space travel is going to be interesting, but it essential that when we imagine the future that we do so while recognizing the glaring problems of today.

You make two very, very large claims that require a deep dive to support.

>With increased technology comes more liberties for all.

...uhm. What? How? Examples? a line of thought? Gimme something here.

>Progress is not made by politicians, it is made by engineers.

Again, what? That's an overwhelmingly naive and narrow view of the world. JFK helped expedite aerospace research, as well as the NASA administrators who didn't do any engineering work but kept the agency running on track? They get no credit in the 'progress'?

Politicians were not partly responsible for the development of long range rocketry and nuclear fusion that came out of WWII?

It's strange to me that people are assuming that when I question the _kind_ of technological advancement being focused on that I'm critiquing _all_ technological advancement. I challenge you to find that critique in my words. Again, I would be most excited about a future where the _primary_ goal of the progress is the reduction of inequality. How can we talk about 'progress' without first talking about the rubric for progress itself? How are we (you) defining progress?

No. Even Elon hasn't given up on Earth — why do you think he's running Tesla?

And the Boring Company… doesn't get any more earthy than this.

Great presentation, only thing I'm worried about is human flight in these things. I mean what happens if this thing is 1% off on the landing? Does the whole thing topple over and blow up into a million pieces? Additionally with the entire flight being automated, what happens if the software gets taken over in space and they just drop it like a rock onto a city? The damage would be catastrophic. We need Elon to invest…

no worse than dropping an airplane on a city

An airplane goes roughly 500km/h. Elons rocket was going 20000km/h - so I think it's about 40x worse actually. Not to mention a rocket goes straight down so none of that speed is lost.
