We're not going to terraform Mars, but we're doing a good job of venusforming Earth.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules

- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.

This is why it's silly hearing billionaires, who do the most damage to our planet, telling us how urgently we need to "get off this rock" which has supported life for millions of years in favor of some dead planet. It's really just an extension of capitalism that demands infinite space to exploit, instead of being content with sustainability.
Elon’s argument for why we need to spread to other planets holds true even if everything on Earth were going perfectly.
It’s not about getting everyone off Earth - it’s about creating a backup for humanity on other planets. This ensures that the only known flame of consciousness in the universe isn’t extinguished by a nuclear war, pandemic, supervolcano, or asteroid impact. It's about not having all your eggs in one basket.
This is not risk free. When you give people access to space and still have terrorism and wars, things can end badly quickly.
There's also a valid argument around where to best focus those resources now. We are nowhere near ready for space colonization on any scale, let alone sustainable ones.
A City on Mars by the Wienersmiths dives into some of these challenges if you are interested.
I think it would be a good idea to start colonizing space before "we have our shit figured out on earth", since you know, that will never actually happen. We will have wars on earth for all eternity, we should colonize and explore space anyway.
Honestly, I strongly believe that striving to make space habitats work is one of the things that will finally teach us what we need to know to live sustainably on earth. The thing is, an affordable space colony is one that recycles almost everything, one that works mostly as a closed loop, a sustainable bubble. So in other words, if you know how to survive in a space colony, you know how to live without destroying the earth. And extreme sustainability is really the natural goal with any large space colony. Unfortunately nobody is really trying to do that here on earth, the funding, the engineering, it just isn't happening. But if we start seriously attempting habitats in space, then people will be attempting that somewhere... And once we figure out how to do it, it can be reapplied to life on earth.
I used to think this way too, or hand wave away all the inconvenients as lessons to be learned, but there is a very valid argument to make that the best thing we can do as a species right now, is to focus inward here before we move out there. Wall before you run type thing. The book mentioned earlier covers a lot of these topics in detail and if you are interested I'd highly recommend as it reshaped my view of the current options. godpseed
Yeah, I've been meaning to read a City on Mars, it's near the top of my list. I have read some excerpts from it though, and from what I've seen, it is trying to tackle these questions from a realistic perspective, but it does also seem overly pessimistic at times.
Btw, your username is awesome.
We will most likely always have terrorism and wars. That's not an argument against letting wealthy individuals fund a private space race.
Yes it is! Right now no one can hurtle an asteroid at earth to end it instantly. When space mining takes off that's a very real threat.
I'm not sure space mining is what causes asteroids. Dinosaurs didn't have a space program to my knowledge.
Space mining can absolutely cause asteroids strikes. It only hasn't done it yet because we haven't done any asteroid mining yet. A big part of asteroid mining operations will likely be asteroid herding, bringing all the asteroids you want to the same place where they can be processed. But moving asteroids around is a potentially dangerous activity.
That said, space is really really really big... It's really hard for two things to hit each other on accident. If you're collecting asteroids at a high earth orbit, the chance of them accidentally hitting earth instead is extremely low. You have to miss your target by over 100,000 miles. Which would be... a monumental failure.
He meant the budget spent on space is enormous and there are more urgent priorities on Earth solve so he does get it.
We already have Mars populated by human-made robots, and one going to Europa moon, terraforming means you're thinking of making it habitable for humans, a huge difference from sending robots to do researches to understand better the moons/asteroids/planets.
The point you try saying his argument which seems against billionaires to be invalid instead of arguing against any other point he made just points out your focus is being an apologist for the wealthy to keep doing what they do best, starve and explore everyone else.
It's private wealth, not government funding. They're free to use their wealth how ever they see fit as long as it's legal.
Ad-hominem is not argument to the contrary either.
Great argument for and example of how the US government isn't taxing wealth nearly enough, if we have homeless people and billionaires funding sci fi fantasies for their own amusement in the same country.
Asteroid impact can solve homelesness too.
I still think populating other planets is a worthy cause. We should do that while taxing the billionaires more.
