Culture War Roundup for the week of May 12, 2025

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.

You're just bringing this exponential out of nowhere

It is not out of nowhere. It's the analogy you selected. It's literally a law of the universe. It's fundamentally just conservation of momentum. It's not some "utterly deranged" statement like your current examples, which are untethered from any mathematical reality of scaling. It's the actual fundamental law of how scaling works for the analogy you selected. In your analogy, they might not have realized where they were on the exponential at the time that they were making great gains; they might not have quite realized how far along they would be able to go before running into this fundamentally exponential scaling curve. But that was the underlying reality of the world.

I mean, how do you think this is supposed to go? "Let's use the analogy of flight, but it's absolutely forbidden to notice that there is a scaling law there, because that would be 'out of nowhere'"?

It really is that simple: flight speed, payload and range isn't capped at some modest multiple above a falcon but by how much fuel you're prepared to burn and whether you're willing to use serious, atomic rockets.

That there is a hard scaling limit is true but it's not remotely relevant to my point since the difference between a bird and a nuclear rocket is so vast as to make any comparison but the most galaxy-brained 'it's all specks of dust from 50,000,000 light years' ridiculous. This should be immediately apparent!

That there is a scaling limit is secondary to where the limit actually is. There is no reason to think we are anywhere near the scaling limit. In rocketry we are limited by our level of investment and our unwillingness to use advanced propulsion, not by physics.

Your whole framing is ridiculous:

Fission, fusion, antimatter, whatever. Yes, we literally did antimatter. The conclusion? None of them give you all that much more in the face of the tyranny of the rocket equation. Certainly not if we're thinking galactic or cluster scale. More? Yes. But in context, underwhelming.

In context, underwhelming because it isn't galactic scale? And by the way, it clearly is galactic scale in a fairly reasonable timespan. Galactic scale in space, why not give it a couple hundred thousand years? A million years is peanuts in astronomical time, in the movements of galaxies or the evolution of life. You're taking an analogy I selected, not understanding it and then producing mixed contexts while complaining about my single, relevant, assumed context of 'things that matter on Earth to real human beings' as opposed to the 'insanity of exponentials and the universe' which doesn't matter to anyone.
