Culture War Roundup for the week of April 10, 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.

I caught this exchange after the previous thread had mostly closed, and I'd like to push back on the claim a little.

BinaryHobo:

I remember talk about just using the excess power to pump water up hill during the day and running it through turbines coming down at night.

Did anything ever come of that?

The_Nybbler:

The physical conditions necessary to make hydro storage practical aren't common.

(How do we do the fancy quotes with user, timestamp, and maybe a link? It'd be useful here.)

It's true that hydroelectric power sources, as in dams, have saturated the supply of naturally-occurring American sites. You need a river in a rocky valley, and there are only so many of those to go around, and once they're used up, it's very hard to create more of them.

What haven't been exhausted, and in fact what can be readily found or exploited, are height differentials in general. Hills, mountains, exhausted mines, deep valleys with no water supply, all offer significant height differentials, are naturally occurring, and can be readily built out into large-scale closed-loop pumped-hydro storage, with a closed reservoir at one extreme and a closed reservoir at the other, and a reversible turbine to generate potential energy in times of excess and power in times of deficit. Should those be exhausted, off-shore dropoffs are an enormous resource of the same, at the cost of more difficult installation and operation in every regard. And if we exhaust THOSE, water towers at sea or underground reservoirs on land can be constructed as well.

All of this, of course, is dumb and America should just take the leash off nuclear, as argued here. (I've not read it yet, but I expect it to make the points I would inline here.) That we haven't yet is a shame and a testament to our collective idiocy and Puritan hangover.

I wonder, is there anyone on The Motte who opposes nuclear power? Either because of concerns relating to safety, waste disposal and other "environmentalist" canards, or because it's supposedly uneconomical.

And if everyone here is pro-nuclear, why is that? Are mottizens just more rational than everyone else, or is it because of chronic contrarianism?

Like embedding a Tweet? I don't think you can do that. But there's a "Copy link" button under every comment and you can put an @ in front of a username so that it links to their profile and they get notified.

The pragmatic argument against nuclear power is just that no one seems willing to fund R&D or construction of new plants. It may be that everyone is reluctant for stupid reasons, but that's the way things stand. I'm still hopeful that some form of improved, miniaturized reactors will be developed despite these obstacles, and be available if the energy situation ever becomes desperate enough for governments to come to their senses and build them.

Because the regulatory barriers are insurmountable.

For literally every rich country? I know that there's some amount of conspiracy regulatory coordination that goes on between different countries, but that seems like a weak argument at the world scale.

For literally every rich country?

China is building new nuclear plants.

China is not a country rich enough to afford environmentalism. (All relevant militaries have nuclear navies for that reason as well.)

That said, China (like Ukraine before them) is also a nation whose culture favors the creation of Dyatlovs; the grand irony is that cultures competent enough to not have their reactors explode in any meaningful way are... also all cultures prosperous enough to afford not building them.

If US citizens were in any position to trust their government like they were coming out of the wartime economy... well, that's why they were able to build out nuclear as rapidly as they did in the first place. Unfortunately, there's no ascendant Germany (or China, for that matter) to salvage that depression in trust this time.
