Culture War Roundup for the week of July 28, 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.

Well, as someone who is highly in favour of this technology being available, I can only hope that the entanglement between the Trump administration and the Thiel/Musk corner of the grey tribe is still strong enough that the Republicans will not be able to mount any coherent opposition to this.

Gattaca is ultimately still a movie, and it had to engage in significant narrative gymnastics to contrive a scenario in which the viewer would be primed to oppose the putative technology. Spoiler, the physical requirements manned spaceflight programmes impose on their astronauts are already unattainable for the vast majority of people. You could have written much of the same plot with no embryonic selection technology involved at all; the only role it plays in the movie is that it lends an element of alien scientific certainty to the judgement, like how people are more comfortable with "faceless bureaucrat rejected your application for credit after looking at your file for 10 seconds" than "AI rejected your application for credit".

Also the main character has a fatal heart condition and says he has a 99% chance of heart failure with a few years. He collapses clutching his chest partway through the film. He is entirely medically unqualified to go on a multiyear space program.

The central point of the film is the opposite of what was intended. They would be right to reject him.

This is just my head cannon (I think), but I always interpreted his terrible heart condition as just him having a normal human heart and not a eugenically selected überheart.

They explain given the state of his heart he probably won't live to see his 32nd birthday. I interpret that as a real issue.

What kind of eugenics does it take to get a head cannon?

I believe the term of art is "skull gun".

No eugenics, but you need to write an email to Joseph Manderley.

I enjoy Gattaca but I also agree that 'Key member of a long spaceflight being at significant risk of heart failure' is something that'd disqualify you right now without looking at your genetic code. The plot would probably feel better if it were pure genemod-bias at play.

For all the hype of the selection process for the first astronaut class --- The Right Stuff is a fantastic movie --- I don't think the current process is anywhere near as physically rigorous. They're probably still fit relative to the populace, but it's no longer quite the standard of perfection they started with. Deke Slayton of the Mercury 7 was grounded at the time for a minor heart issue, but got to fly later, and John Glenn was pretty old (77) when he flew again on the Space Shuttle in 1998.

The original flights had to work, right? They were America's way of showing superiority to the Russians and to Communism. Now that it's just another tour of service, albeit an unusual one, I'm not surprised standards have been relaxed.

The combination of better automation, simpler missions (and in particular not going behind the Moon and therefore potentially having to carry out manoeuvres while out of comms with Earth) and more payload meant that the Shuttle could afford to carry passengers in a way that earlier missions could not.

Early space suits were very hard to work in because constant-volume flexible pressure vessels are hard. This has gotten better, but isn't a fully solved problem. In much the same way that early aircraft required large forces on the controls (flying a B-17 I'm told is an arm workout on a good day, doubly so when the trim settings are damaged). It doesn't take a serious bodybuilder to fly an Airbus today, though.
