Culture War Roundup for the week of April 20, 2026

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.

is the recent spate of deaths among American and Chinese scientists the beginning of a -hot- warm war with China?

From Newsweek: Chinese Scientists Have Been Dying Mysterious Deaths Too

The star of China's booming artificial intelligence defense sector had been working on Taiwan invasion scenarios—until he died in an unexplained car crash in the early hours of the morning in Beijing, aged just 38.

Many questions remain over the July 1, 2023 death of Feng Yanghe, a professor at the National University of Defense Technology, who had won national competitions with his pioneering "War Skull" platform. Such as, why did an obituary in the state-run science news website, Sciencenet .cn, say he was "sacrificed"? Why was the brilliant scientist from Gansu province buried in a special cemetery in Beijing for the Communist Party elite, state heroes, and revolutionary martyrs?

The phenomenon mirrors the wave of disappearances or deaths among American scientists that is now being investigated by Washington. In the U.S, there have been 11 cases, in China at least nine. It's prompted a disturbing question among some military analysts: Is there a silent "scientist war" going on?

”Feng was a mastermind behind AI simulations of potential Taiwan scenarios and it's very odd that the accident happened in the middle of the night," said an experienced researcher of the Chinese military who works at a Western think tank and who has been monitoring the situation.

The author is a senior reporter for Newsweek, with publications in the NYT and some other major publications. She is also a former senior fellow in the Asia Program at the German Council on Foreign Relations and a nonresident senior fellow in the Atlantic Council’s Global China Hub. Not a crackpot contributor as might be expected from the insane premise! She seems to have connections within the Chinese circle of influence.

If there’s really a tit for tat of targetting each other’s scientists, then I think our immigration policy will prove to be a grave mistake. There are 265,000 Chinese students in America, and probably hundreds of thousands of Chinese who own or work in the huge nationwide Chinese restaurant industry. The CCP would be able to place agents around America with complete ease. America would have a difficult time doing the same. We saw recently in Iran how effective it is to place drones around an enemy country, and Iranians were so afraid of threats from their immigrant community that they deported 1.5 million Afghans.

This theory would explain why America has had disappearances and not just deaths:

Also missing is William Neil McCasland, a retired Air Force major general, who hasn’t been seen since he walked out of his Albuquerque, New Mexico, home on February 27, leaving behind his phone, prescription glasses and wearable devices […] McCasland was at the center of some of the Pentagon’s most advanced aerospace research and once commanded the Air Force Research Laboratory at Wright-Patterson Air Force Base. Months after the 68-year-old went missing, officials still can’t say where he went, why he left or whether someone else was involved.

The above sounds to me like a VIP being escorted to a safe area where he can’t possibly be targeted, hence the leaving behind of electronics.

behind AI simulations of potential Taiwan scenarios

Not to derail, but does anyone have any idea of what this actually means? I work with defense modeling and sims folks and I am an AI/ML person but whenever I hear the words AI Simulations I'm left scratching my head. Is this just making world sims for RL models? But then why would you be training an RL model to invade Taiwan? Simulations are generally done on big HPC rigs with tons of variables, ie. Finite Element Modeling. This isn't something that really benefits from neural nets. Maybe my technical classification is different than the non-technical, but this guy is supposedly some researcher I feel like the classification would be more precise.

Could be referring to AlphaGo, AlphaZero, and the follow ups of RL models that play Starcraft and other games, but moved to military scenarios. You would have one model invading Taiwan, the other model defending Taiwan, and they play each other. But of course you can’t train a model to defend Taiwan without training a model to invade Taiwan.

These fall into the RL side, specifically Model-based RL. The dirty open secret about model based RL is that the RL-policies(ml-models) trained are only as good as the sim-models (there are two types of "models" here that mean different things, smh...), they don't generalize well. So for the RL trained on Starcraft, it is also then tested on Starcraft, so good training results in good testing results. The major leap comes when you transfer it to a real world scenario, where it will not perform, because Starcraft is not a good model of the real world. Part of this is strictly technical, RL models/policies learn a mapping of states to actions, ie which action to take in a given state for the best reward now or in the future. The Starcraft world actions don't exist in reality. The models don't really learn high level tactics that can be extracted and re-used (unfortunately)

Modeling the real world with finite states is probably impossible. Near infinite/continuous states is going to be insanely hard to model, so if they are doing this, then good luck but it's a likely dead end.
