Culture War Roundup for the week of October 17, 2022

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.

From /u/gwern (@gwern ?): analysis on China’s semiconductor industry.

Recent export controls are directly targeting the Chinese ability to fabricate cutting-edge chips. The subsequent effect on electronics prices and the much-maligned supply chain won’t be pleasant—especially for China, and especially if their industry is already slumping. Consequences for the rest of the world are left as an exercise to the reader.

Given the forum, it’s not surprising that the focus is on AI. I’m more interested in the geopolitical outlook. This is an incentive to retaliate, perhaps even against the other regional semiconductor fabricator. And it is suggested that the timing is a calculated insult to Chinese leadership, as they are apparently going through a periodic dog-and-pony show of elections. Gwern suggests that China would otherwise be raising hell.

The counterpart in US domestic politics: crunching semiconductor supply will not mix well with inflation. I don’t think adding $50 to the next iPhone will make or break Democrats, but it seems unlikely to help.

I want to place predictions, but I don’t have a good grasp of the metrics involved. Place your bets, I guess, for:

  • China taking economic action

  • China taking military action

  • Consequences on Chinese industry

  • Tech policy towards China becoming a wedge issue in American politics

My greatest hope with these export controls are that they're merely graft. Biden has been championing the domestic semiconductor industry, with Congress granting tens of billions in subsidies to build domestic manufacturing. Maybe he's getting a kickback from the companies that benefit. Not the actual semiconductor companies, but the firms and unions involved in constructing and maintaining these specific facilities.

The alternative is that this is preparation for imminent war. The administration are not so dumb that they think this will permanently hinder Chinese industry. I've seen experts forecast that they'll probably be able to develop what they need in 2-3 years.

Why disrupt American industry so greatly for a mere 2-3 years of strategic advantage?

As Gwern points out, this may provoke a response from China. America dictating to a Taiwanese company that it can't sell its wares to China certainly seems like a violation of at least the spirit of the vague One China policy. That's a policy that the West already gets almost all of the benefit from. All China gets out of it is face-saving. The West and Taiwan get to treat Taiwan like a country in every way except name. They even get to have diplomatic relations, and embassies, just by another name.

What would America do if China controlled a vast amount of the world's rare earth mineral mines and decided that they'll no longer sell the products of those mines to America or its allies? Wait, they already do control a vast amount of rare earth minerals. Maybe that's the next step in this dumb escalatory spiral.

What if it were laughably trivial, and instead China secured exclusive access to all avocados grown south of the United States border? Would the United States do nothing?

That's what the Chinese did to Japan during the dispute over the Senkaku/Diaoyu islands, they suspended rare earth exports.

One thing about rare earths (or any resource really) is that there is a nearly unlimited supply at the right price. While China could hamper some industry temporarily, there are plenty of rare Earths available elsewhere, they just aren't economical to extract at current prices.
