Culture War Roundup for the week of May 13, 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.

In the spirit of bringing life into the thread, I thought I’d share something a little different.

Dozens of stars show signs of hosting advanced alien civilizations

Two surveys of millions of stars in our galaxy have revealed mysterious spikes in infrared heat coming from dozens of them.

A summary won’t do it justice, and I encourage anyone interested to read the linked article; it’s not long. In short, though, researchers checked out approximately 5 million stars (in our galaxy—close enough to look well at and potentially one day visit) for anomalous ratios of infrared heat to light. The idea here is that if a star is giving off a lot of light that is being captured, it will heat whatever is doing the capturing up significantly. This is suggested to be possibly due to either unusual debris fields around these stars, which would be unexpected due to their age (most planetary collisions happening early on in a solar system’s lifetime, and these stars being older)… Or due to large amounts of sun-orbiting satellites soaking up solar power, a Dyson swarm. Our exoplanet imaging is still very much in its infancy, and we have already discovered planets that seem to bear biosignatures. The latter explanation is plausible, at least.

This is pretty far from standard culture-war fare, but I suspect that there are enough rationalists and futurists here to find it interesting. There are also a few potential links:

    1. What does the future of our society look in a universe where life is entropically favorable? That is to say, what if life is not rare, and instead happens consistently whenever the right conditions are present for long enough?

This implies that there is either a way through the theorized AI apocalypse, or perhaps that silicon-based life continues growing after taking over from carbon-based life (the “biological boot loader” thesis). While I’m rather attached to my carbon-based existence, it’s at least heartening that in this scenario something is still happening after AI takes over; the spark of life hasn’t left the universe. Unless all that power is going to making paperclips, I suppose.

    1. What sort of societal organization is optimal for a galaxy in which we can expect to interact with numerous alien civilizations? We have (thankfully) yet to encounter grabby aliens, but the game theory seems logical; in an environment where there are limited resources and an ever-expanding population, conflict is inevitable (by historical earth standards).

Does it make sense to enforce population control on a cosmic scale, discouraging humans from expanding to other stars to avoid conflict? Could the “dark forest” hypothesis make sense, where offense is favored over defense and civilizations hide as much as possible?

    1. If we were to travel to other stars in the distant future, would the expected travel times result in human speciation, or such a long remove that cultural exchange and even biological exchange is kept to a minimum? Or is there an “optimal human”, which genetic engineering and biotech could potentially bring us towards as a local maximum?
    1. Is this all bullshit, and are we alone in the universe, forevermore?
    1. Does anyone have any thoughts on the spate of propellantless propulsion efforts currently being made? Somewhat like perpetual motion machines, or room temperature superconductors, or fusion… This is a topic that has very high expected returns, and thus a high expected gain in fame or financing from lying about experimental results. But I do note that fusion seems to be moving forward; while LK-99 didn’t pan out, there are still groups working on things inspired by it, and it seems like lessons learned are leading to next generation superconductors. My point here is that if the laws of physics allow it, we seem likely to eventually create it… And we are yet to discover a Theory of Everything, so who’s to say whether something like propellantless propulsion is possible?

Mods, I apologize in advance if this is insufficiently culture-war adjacent to deserve posting here. I didn’t think it worthy of its own thread, and feel like it’s perhaps healthy for the Motte to have some fresh topics as well. I’m a devoted lurker and thought I should do my part.

Edit- My list got butchered. Trying to fix it, but it seems the method I chose of writing multiple paragraphs after a question is disfavored.

Assuming our current understanding of physics holds, much of this doesn’t matter. If there are Taelons 100 million ly away from us, it is highly unlikely they’d care about us. We don’t have anything they don’t already have. So hiding makes no sense — it would take them millions of years to get here, for no gain. You can find most of the material in our solar system in thousands of other places much closer to the alien planets and can extract them without having to mess with people or other animals.

And from the other end, it’s all speculative. The aliens are undoubtedly weirder than we can possibly imagine, and our views on culture and government are largely based on our own history. And I’m not sure what these aliens have to do with AI. Maybe they solved the alignment issue, or maybe they destroyed all their AI and have been huffing Spice. They might have stalled on on technology before AGI. We don’t know anything and frankly can’t know anything. We found some odd chemical signatures, that’s it. Trying to pointlessly speculate on what this means for the future of space travel, propulsion, AGI, or alien human relationships is premature in my view. This might be something interesting, but it might not.

If there are Taelons 100 million ly away from us, it is highly unlikely they’d care about us.

Milky way diameter is only around 100 thousand ly, the closest Andromeda galaxy is 2,4 million ly. Even Voyager is travelling around 1 ly/18,000 yeas so it can get to the edge of the galaxy in around 900 million years. Parker Solar Probe, which is fastest moving man-made object has ten times the velocity, so it could travel to the edge of the galaxy in tens of millions of years.

Any sufficiently old civilization - let's say tens or hundreds of millions of years old - could reasonably have a probe in every star system in the Galaxy even with our current propulsion technology with no problem and it could even explore other galaxies if it is 1 billion years or older.

it is highly unlikely they’d care about us. We don’t have anything they don’t already have.

We extensively study all sorts of animal and microbial species here on earth, simply out of curiosity, even though these species don't "have anything" for us. Sometimes this research leads to medical advancements, but usually it doesn't. Most academic research is in the same boat. There's no "practical" reason to study obscure religious treatises from late antiquity, or the cultural practices of a hunter-gatherer tribe in Africa, but people do it anyway.

The aliens are undoubtedly weirder than we can possibly imagine

Maybe. But if they are, then that means that we'd be impossibly weird to them! Which would make us rather more interesting.

Of course, it's an open empirical question whether aliens would find any value in studying us or interacting with us. Maybe they would, maybe they wouldn't. But thinking that humans couldn't possibly be interesting to a scientifically advanced alien intelligence is just as much of an unfounded bias as thinking that humans are always at the center of the universe.

Studying and interacting is much different than expending considerable resources on something, which in turn is much different than waging war or making large economic investments in something. Sure, we spend money on researching things out of curiosity already, but it's not a lot. Numbers are hard to come by, but one figure I saw says we spent about $7.2 billion on botanical research in 2013. However, the context of this figure was talking about money spent on crop science research, and I'd be willing to bet that the money spent on projects like some professor studying rare ferns of Appalachia is much less than what we're spending on more practical applications. If an alien civilization were to visit earth from the distances described, it would be an incredibly costly mission with no guarantee of success. My guess is that if they wanted to study us they'd send unmanned vehicles first, then maybe a small research party like at the beginning of E.T. I highly doubt they'd come here with cargo ships ready to exchange resources for technology, let alone bring an army to mount a full-scale invasion. After all, we've been sending stuff into space for 60 years and we still haven't got past the curiosity stage yet, with the exception of satellites that are within driving distance. We certainly haven't gotten to the point where it makes sense to start mining the moon or something similar, and that's practically right on top of us in astronomical terms.
