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.

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.

I mean, we're talking about the possibility of a super intelligence that is going to tile the universe with paperclips, and you want to say that your own analogy is too galaxy-brained? Ok, buddy.

That there is a scaling limit is secondary to where the limit actually is.

Correct. There was a scaling limit back when the Wright brothers first took to the air. It was still there when we went to the moon. At what point did we realize what the scaling limits actually looked like?

There is no reason to think we are anywhere near the scaling limit.

Right now, there's not really that much reason to think that we're not, either. We have basically no theory here yet. No idea whether the scaling is truly exponential or something else or where we might be on the curve.

In rocketry we are limited by our level of investment and our unwillingness to use advanced propulsion, not by physics.

If you ignore the exponential that comes from physics, then sure.

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?

No. It is "certainly not" that much more if we're thinking galactic scale. It's just underwhelming in general, in context of the exponential of the rocket equation. You can just look at the numbers and say, "Yeah, that's more, but it's not all that much more."
