Culture War Roundup for the week of March 6, 2023

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

As with so many things in space, I think the timeline is driven by one binary variable: does SpaceX's vision of a rapidly reusable Starship come to fruition?

If it does, asteroid mining goes from a pipe dream to a reality in the blink of an eye. So many things that work in principle work in reality once you can toss a hundred tons to orbit every day of the week.

doing complicated construction in space and getting autonomous miners where they need to be, then maneuvering the mined material back to earth and getting it back down is the kind of thing that has hundreds of steps just as hard as being able to reuse the rockets. Hell, if you asked someone smart who didn't already know how hard of a problem it was having reusable launch crafts probably wouldn't even come up on their list of hard problems.

Oh, certainly, I'm not saying the only thing holding us back from von Neumann probes and a Dyson sphere is mass to orbit! But if you skip autonomy, on orbit mining, and on-orbit manufacturing, you can still make a business case for the simplest asteroid mining possible:

  1. Identify asteroid with 100 tons of platinum

  2. Launch intercept/dock mission a la Hayabusa

  3. Slow burn for intercept course with Earth using ion propulsion a la Dawn (not to mention Starlink and a million Soviet spacecraft)

  4. Crash it in the desert and recover contents

100 tons of platinum is only a couple billion dollars, so this only works once launch prices for the monstrous probe necessary for something like this are reasonable and you can cut costs on the probe by removing the anal mass optimization currently necessary.

This is obviously far less revolutionary than true asteroid mining with on-orbit processing and manufacturing, which is what will kickstart the off-Earth economy, if we ever get there. Still, it's a start.
