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.

Starship bet update
A few years ago I made a series of bets about Starship making it to orbit with other posters, last rounded up here:
The last one is a real nail-biter. When I heard about the SpaceX IPO I first thought it's time to call it a day. My model for my predictions about Elon was that he has a hype-compulsion, making wilder and wilder promises to get money out of investors, and as it becomes clear he won't be able to reach the hyped up goal, at some point they will get fed up with him. So when the news of the $85.7 billion came out, I figured that even if I do win, it will be on a technicality - maybe they won't pull it off by end of this year, but this sort of money will surely be enough to get them over whatever humps they run into on the road.... Then again maybe not! It also turned out that they have $41.3 billion in accumulated losses since their founding, and have burned $4.3 billion on AI in Q1 2026 alone, so maybe I will lose on a technicality instead, where they will indeed get to orbit by end of year, but will be dragged down by the unprofitable parts of the company.
I now believe that such a "loss on a technicality" is a pretty likely outcome, precisely because of the IPO. Like I said last year, if my bet was with Elon, he probably could have ordered the damn rocket to be put in orbit, just to prove a point, and while I'm lucky enough to have made my bet with internet randos instead, the IPO changes the dynamics such that he will be very tempted to do such things just to prove a point. Currently 95% of SpaceX stock held by insiders is locked up and it will be gradually released over the course of the year. Stonks are largely guided by hype, hype is generated with media articles (such as "SpaceX makes history with Starship orbital launch!!!11"), so while a frivolous orbital launch would make little sense before, it could make a lot of sense now. There's already talk of Starship 14 being orbital, and I fully expect them to schedule it just before one of these unlock dates.
That said, it's not over until it's over! Just because they might want to do it, doesn't mean they'll pull it off. This whole bet is starting to feel like an episode of Wacky Races.
This post gets to the heart of what my problem with the space colonization hype train that seems to be popular on this site. What exactly is the profit motive? Starlink seems very useful and profitable. Colonizing Mars? Not so much, unless investors are willing to eat losses for many decades.
From Inadequate Equilibria by Eliezer Yudkowsky:
The point of going to Mars is to flee the game. To Escape From Terra to a place where the looters and moochers cannot reach us. "Men will endure bitter poverty, cold isolation, drink piss and eat lichen just for a chance to be free from the tyranny of the United Nations." Or, as Heinlein put it:
Unless our current model of physics is totally wrong, space will not be a population frontier, ever. The real answer is, of course, violence. As national governments reduce violence, they reduce their own capacity for it, which inflates the value. Eventually the value gets high enough and the numbers of people who can produce it low enough that the two meet and a revolution, coup or invasion happens. This is almost always a losing proposition for the country in question, but it offers a platform to try radical new things, and the ones that work get more widely adopted.
The French Revolution was a disaster for France, and most of Europe. Most of their innovations were insane bullshit and were swiftly forgotten. But they did fix a bunch of issues with the legacy legal system and spread that to most of Europe, giving the continent a much better set of legal standards which contributed to trade, diplomacy and the eventual peace and unity of Europe. Just needed a dozen major wars, two world wars, a few genocides and a lot of ethnic cleansing to shake it all out.
Progress is produced in blood, not economics, philosophy or science. In the most anti-progressive and civilizationally corrosive manner. "Creative destruction" as an economist might say. It is by this bloody cycle that humanity progresses.
...what in physics forbids space being a population frontier?
That's the point. People act like "not forbidden" equals possible and technically it does, but only technically. Physics doesn't prevent me from slaughtering my way through Parliament and Buckingham Place with a slingshot and declaring myself Emperor of England, but it's not going to happen.
Being a population frontier has to mean being realistically somewhere will populate. The Americas were unpleasant in many respects, but they were on Earth and people believed they contained pretty good farmland, which often did turn out to be the case. They were also breathable, and full of lumber etc. Finally, people weren't really able to communicate with them, leaving space for hope.
Space just doesn't compare in that regard. If you can't make space at least as comfortable as the Americas then or e.g. the Congo now, people aren't going.
Sure, but I don't invoke the laws of physics to say you can't do that.
Making it that way is not particularly difficult as a physics challenge. Building underground domes on Mars or the Moon or a spin ring in orbit is physically doable, no question about it. I agree that it remains to be seen if human desire to do these things outweighs the difficulty to do them, but they're not laws-of-physics sorts of problems, and most of them have been on-paper solved for 50 years or more.
But you’re still broadly conflating ‘doable’ with plausible and rewarding.
The point is that physics precludes space being a frontier by making it so unpleasant to go and live there that nobody will. The same way it precludes underwater settlements - it’s not that we can’t build on shallow waters but that physics makes it less pleasant than the alternatives.
No, I am not, not in this conversation thread. Insisting that something is physically possible is not the same thing as insisting that it is plausible and rewarding. It is physically possible to eat gravel; it's not plausible that I had it for dinner and it would not be rewarding for me, had I had it for dinner (I didn't), but if you said it was physically impossible I would dispute the claim – unless you were a child. Then I might encourage your naïveté on the grounds that enlightening you as to the possibility of lithophagy at such a tender age might not prove conducive to your continued health and well-being.
I think it's quite possible that space travel will indeed be so dangerous, dull, and expensive that no one will attempt space colonization! That's well within the realm of possibility! But I think it's unusual to describe this as downstream of the laws of physics. Indeed, one might argue that the laws of physics dictate the opposite: a sufficiently large object traveling in space can be so comfortable that the vast majority of people who live on it would never dream of going elsewhere.
If there are any laws that dictate what you're claiming, they are almost certainly economic.
