Culture War Roundup for the week of October 7, 2024

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 are seeing what the early part of an era of exploration or expansion looks like.

(...)

Then given that we are literally on the 5th test flight ever of a new degree of capability, historically speaking 50 years from now would be very soon, let alone 15 or 5.

That's all fine, but shouldn't we then leave declaring new eras of exploration to historians? With everything you've written, it sounds like something that won't become apparent for quite a while.

For example, the Saturn 5 rocket of the Apollo program to the moon had a LEO lift capacity of 118 tons, and about $5.5k per kg. The Starship is expected to have a LEO lift capacity of 100-150 tons, with a forecasted cost of around $1.6k per kg... possibly falling to $0.15kg ($150/kg) over time due to to reusability reduce the cost per flight as you don't have to keep re-making the whole thing.

There's a few issues here. One is - wasn't Saturn 5 optimized for the flight to the moon? It could deliver 50 tons to the moon in a single shot. Starship might have good (forecasted) performance to LEO, but it simply cannot make it to the moon, and even according to best case scenario projections will need a dozen or so refueling launches to reach the moon.

The second problem I have is the "falling over time do tue reusability", why hasn't this happened with Falcon 9? I consider it's announced costs to be a bit sus in themselves, but even taking them at face value, you don't see them dropping over time.

Finally, the third problem is that it's a forecasted cost. Musk's entire MO is announcing some product promising insane performance, falling way short, but acting like he delivered because you can buy something that looks vaguely like the announced product. Wasn't self-driving supposed to be safer than a human driver 7 years ago? Wasn't the Cybertruck supposed to be nearly indestructible and cost as low as $40K? Wasn't the Roadster supposed to be in production in 2019, and offer some insane range like 600 miles? Wasn't the Semi supposed to beat Diesel trucks in terms of costs, be competitive with rail, and be guaranteed to not break for a million miles? Wasn't the Boring Company supposed to cut tunnel costs to a fraction of what they were? What makes you so sure he'll deliver on Starship any better than he did on any of those?

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
