The word "planning" in the quote "with billionaires planning to move humanity to Mars in the near future" is a link to another article: https://aeon.co/essays/elon-musk-puts-his-case-for-a-multi-p... The top of that article says, "Elon Musk argues that we must put a million people on Mars if we are to ensure that humanity has a future."

I agree. Which is why I think the fanciful idea of a Mars colony is nothing more than a hand-wavy distraction at this point, designed to propagandize a billionaire's other projects to gullible sci-fi enthusiasts.

> the natural environment will select for What do you mean by this? Natural selection AKA "survival of the fittest" only works over the course of thousands or millions of years. Otherwise, Mars would be pretty much stuck with whatever people it (hypothetically) had. Especially if you're talking about a colony that decides to make itself independent of Earth. On Earth, we can be selective of who we would (hypothetical…

> the natural environment will select...What do you mean by this? The initial group of settlers will self-select themselves; not many of us are willing to live in such harsh conditions. Kids that grow up in this environment are likely to develop grit and cooperative spirit, and they will see first-hand how it is necessary just to survive.

> Kids that grow up in this environment are likely to develop grit and cooperative spirit

Alternatively, they may grow up dispirited and disillusioned, because they had no choice in the matter. Maybe they'll want to leave Mars and go to Earth. Or maybe they'll just be pissed off and lazy, wanting to watch the world burn, so to speak.

If you want to keep the kids in line, you'd better have a totalitarian government that restricts their access to information, to prevent them from discovering that life on Earth is so much better than their own miserable lives.

That's just magic woo though. You can't just "3D print" a clean room to build semiconductors or furnaces to smelt metal. Pretty much all heavy industry on Earth that makes all our high technology runs on petroleum products in some fashion. You can't just "3D print" lubrication and good luck building heavy industrial pieces without it.

Hmmm. While I would be actively surprised if the Moon, for example, had every element necessary for semiconductors, one of the things I absolutely do expect to be possible on its surface is 3D printing an extremely clean clean-room. Furnaces? Well, I think it would take a polishing step after printing, but if you have aluminium you can do a rough parabola out of it and focus sunlight on a patch of regolith. Can you t…

> While I would be actively surprised if the Moon, for example, had every element necessary for semiconductors

As I understand it, the currently accepted theory about how the moon formed is the giant-impact hypothesis, which is that a very large object hit the proto-Earth and the moon is the material that was "splashed" off when this happened. As such it seems at least plausible that the moon would have a similar set of elements available for semiconductor production as Earth does.

There are some that see the glass half full, but I've never before encountered someone that sees half a glass and thinks there's an Olympic swimming pool.

Perhaps you've heard of this country called China. A country that was as poor as the places in West Africa that you've written off. In 4 decades, they pulled hundreds of millions out of poverty. As a result, they are now facing a demographic crash that will shrink their population nearly in half: https://www.pewresearch.org/fact-tank/2022/12/05/key-facts-a... This isn't exactly going to be a nice situation for them,…

> Perhaps you've heard of this country called China. A country that was as poor as the places in West Africa that you've written off. In 4 decades, they pulled hundreds of millions out of poverty.

China's poverty rate has decreased massively in the last 40 years, and at about a rate of 3.2% between 2017-2019. In 2019, China's poverty rate was 15.8%. There are 1.412B people in China, which means that in 2019 over 223M people in China lived below the poverty line. There are 209,128,094 adults in the US over 18yo, which means about 14M more people in China live in poverty than there are adults in the US.

     A new report from one of China's top universities found that wealth and income inequality in the country is getting steadily worse. According to the report, one-third of the country's wealth is owned by the top 1 percent of households, while the bottom 25 percent account for only 1 percent of wealth.[1] 

     The Chinese political system is authoritarian. There are no freely elected national leaders, political opposition is suppressed, all religious activity is controlled by the CCP, dissent is not permitted and civil rights are curtailed. Elections in China occur under a single-party authoritarian political system.[2] 

     General Secretary Xi reaffirms China's close ties with Russia, saying “China is willing to work with Russia to continue supporting each other on their respective core interests concerning sovereignty and security.”[3]

     The head of Taiwan's National Security Bureau recently told lawmakers that even if China invaded, they wouldn't be able to continue TSMC's operation. So, there's no need for crazy contingencies like blowing up TSMC factories.[4]
If China is your Gold Standard other societies should aspire to, I would only direct you to look at the facts and encourage you to abandon your rose colored glasses. China supports Russia which is by many accounts a Mafia State. China has been on the verge of invading Taiwan for decades, which will certainly be devastating to computer technology, but could very well start World War III and cripple all functioning societies.

> You misunderstand my position as being wildly optimistic. You simply don't understand contemporary human societies, so your assumptions about their trajectories miss the mark completely.

False. Your position is absurdly optimistic on its face. What I understand or don't understand and whatever assumptions you imagine I have made is entirely irrelevant to the argument I have presented. What you have done is ignored my argument and employed fallacious argument, including ad hominem and straw man arguments, as well as hand-waving and non-response. Optimism is good. But your position is ignoring the reality of the current global environmental situation, all practicality, and glazes over the massive amount of change that must occur within decades if the Earth is to be stopped from a cascading self-sustaining man-made global catastrophe.

We must change, and that requires individual and societal sacrifice on a scale so mind-boggling it has never before been seen or conceived. We need optimism, but we also need to be realistic, practical and yet extremely vigilant to reduce our energy appetites, commercial indulgences, and tremendous wastefulness. Individuals can't do it alone. We need all of Earth's governments to cooperate.

And yet at the eleventh hour, one sociopathic government is holding the world hostage, and a couple other like-minded governments, one of them critically important, is supporting that sociopathic government's criminal and unethical actions, and I mean the war in Ukraine.

Meanwhile at home in the US a conservative minority is holding the country hostage while bamboozling nearly all of its political members into propping up the richest of the rich at their own personal economic expense and economic stagnation. We have so much to do, yet we have this thorn in our side that is anti-education, anti-environment, anti-government, narcissistic, misogynistic, anti-equality, anti-facts, pro-conspiracy, pro-pollution and pro-energy consumption.

The situation is dire and the future is bleak unless we can wake people up to reality. I've begun with you. Please, please wake up, and wake up others that have been living in a fantasy world. We need you and them here to help, beginning by going without, but also exclusively voting towards personal economic interests and ignoring all other distractions such as gun rights and abortion, i.e. what will help the voter economically right now, which is an atmosphere of opportunity, which requires abandoning voting for the fantasy of someday when wealth may or may not arrive. Because if the rich continue to be propped up, economic advancement will never occur for the average voter and the vast majority of voters. Don't worry about the rich. They always land on top. Worry about ourselves.

The concept of planet B is itself ideological. Climate change is a symptom of capitalism; which remains unchallenged. Why is it easier to imagine a zombie apocalypse than a different economic system. Varoufakis Another Now attempts this. Until we are able to imagine new economic structures our attempts to avoid "planet B" will continue to create new markets and that is it.

This article is full of strawman arguments. I'm not aware of anyone who's arguing for moving billions of humans to another planet or for dedicating the resources of Earth to terraform Mars. It's not like Mars colonization proponents are keeping their plans secret - the authors could easily have googled what the actual propositions are, to wit: - Use current or near-current tech to send human missions to Mars - Use ex…

As someone who is generally pro-Mars colonization (and has Zubrin’s book), I feel this. We don’t need to dichotomize this and I welcome advances towards humans going beyond where we have ever been.

At the same time, I realize there is a lot of pain and anxiety down here. The environment is being wrecked. Climate is changing beyond what an evolved ecosystem can handle. At the same time, there are poor nations trying to catch up, who will not like being told to slow down by the developed world. With collective action global poverty could be solved in the next 10 years. The worst of it, anyway. But suddenly the argument becomes that by giving a dollar to space exploration you are depriving a starving person? I simply cannot accept that hardline utilitarianism.

Unfortunately, being just some internet person, I don’t have numbers on how much to spend on space technology. What should it be at this point in time, in comparison to all of our other needs? All I can say is greater than zero.

Let's set aside the part that making a planet where we could live is hard. Just presume we did that, to start. Let's talk Logistics . Presume there are only 1 billion people left on Earth when we decide it's time to go. How do you get them there ? The gravity well holding us here (and holding the air down so we can breath it) is pretty darn strong. Today we're hoping to get cost-to-orbit down to around $100/kg. I wei…

> Just presume we did that, to start.

While I'm fully on board with the thrust of your post, I think skipping this obvious first question is kind of missing the point. Terraforming Mars would be such an enormous, slow, expensive, intensive process that any other problems with "logistics" would be long solved before we ever got past that initial challenge.

> If we can make Mars habitable, we can make Earth habitable for far less cost.

Ultimately this summarises it best: I don't really think logistics would be a problem if we solved making Mars habitable - I just don't think doing that is worthwhile to begin with.

I’ve read most responses to this, here’s my take:

1) The overall concept would be a lot clearer if it were called Earth2 instead of “Planet B”. I agree it’s unlikely we’ll find something suitable “nearby” without terraforming.

2) We know there’s no Earth2 in our solar system.

3) There is no foreseeable path to interstellar travel other than generation ships, presumably after advance scouting. This is not worth considering with present technology. Time horizon for suitable technology is unknown.

4) Saving Earth and colonizing space are NOT mutually exclusive.

5) Abundant, clean energy resources are the only sane path to preserving Earth in more or less its present state. A rising standard of living is associated with lower (or no) population growth, and a cleaner environment.

6) Given sufficient energy, and expertise in interplanetary travel, the Moon and Mars can both become very nice habitats for humans. Almost all day-to-day existence will take place underground. Centrifuges may be needed for physiological reasons (shame on NASA for not studying this sufficiently).

7) Strictly space-based habitats may be better (one G centrifugal force is easy), the downside being that all materials must be transported from elsewhere unless asteroids are converted to habitats. Space habitats will require radiation shielding equivalent to a few feet of concrete.

8) The key thing for all of this, and also for improving standards of living for Earth-dwellers, is abundant energy. The only way to clean up our act on Earth is with massive energy abundance.

9) Solar can help everywhere, and wind can be part of Earth-based solutions, but advanced energy sources like fission and fusion MUST be used as part of the solution.

10) Nuclear powered space travel should be (and is in fact becoming) a priority. An intense focus on advanced space travel may eventually make interstellar travel possible.

11) It’s likely possible that given robust interplanetary travel, the Solar System alone could support a sustainable human population in the tens to hundreds of billions, as well as Earth being a near-pristine “life preserve” with a population of just a few billion.

12) More people should be getting STEM educations. ;-)
