I’m getting lost and confused here.
I think Dawkin’s God meme refers to all kinds of religious thought; of all practices ascribing cause to unknown capricious forces beyond control, but it’s been a while since I’ve read it and that might be a generous interpretation.
There is information, and there is context, and information in the right context can self-replicate. This framework applies to both memes and genes. Your analogy framework states that the two are not necessarily identical, and I agree. But this, as you say, does not preclude analogy from having its revelatory function.
I think evolutionary lens to look at memes is an interesting one, even if it does not explain everything. I think it’s most misleading from a competition aspect, as only mutually exclusive ideas compete to extinction (other than vague definitions of attention), and you rightly point out that mutation of ideas is a much less random processes.

I agree that the mutation of memes is quite distinct from the random mutations of genes; the remixing of memes can be thought of akin to recombination, but there is a lot less random noise. That being said, certain biological systems have bias towards certain kinds of mutations, but I agree that the generation of variation is extremely different between the two.
I guess I should flip it, as “the agent will spread memes that it thinks are beneficial to spread”, the same way that a cell will spread viruses that are capable of hijacking their machinery. I think the meme exists separately from the distortion as information; it can be encoded in many different ways (in speech, in text, as an image, etc.). Decoding the information requires a cultural context, and the cultural context also shapes the virulence of the spread.
(or rather, “agents are machines that perform behaviors towards increasing fitness, and memes are information shaped in ways that appear that spreading them increases fitness.”)
(though I think it would be good to take a step back and stop inscribing agency on genes, memes and people, the last of which is controversial but cells don’t have agency so it’s probably good to frame the two similarly, unless that’s a crux)
I don’t think the information we largely communicate every day are good memes. The juiciest gossip is virulent due to status games, but most communicated information are probably barely about the informational content at all, and more about reinforcing bonds and maintaining a shared culture (and shared cultures are important when trying to communicate important information).
For both memes and genetics, there is the information, and there is the context. The right information with the right context can replicate the information and spread it, and if it finds the right context again, it occurs recursively.
(although memes, unlike genes, cannot be vertically transmitted, since it uses the same method of transmission as horizontal transmission.)

I agree with the problem of analogy, but I disagree with the use of memetics as an example.
You can apply the same criticisms to genetics to prove that genetics doesn’t work. Genes don’t work in isolation; in order for the gene for penicillin resistance to work, it requires at the very least all the genes requires for DNA and RNA replication, protein translation, a large subset of metabolism genes, and all the genes involved in replication in order to observe the result. Genes by themselves are merely underspecified encodings of useful information, which only mostly function because most life share mostly the same language (though there are many incompatibilities in codons usage between groups). The final function of a gene is heavily dependent on the context it finds itself in, the same as a meme embedded in a culture. Often, in both cases, they are unintelligible and useless.
The “replication with low variance” is also something selected for. A simple language evolution experiment showed that languages become more learnable over time (Kirby, Cornish & Smith, 2008), because memes that are more easily transmitted (successfully) are, well, more easily transmitted. You cannot assume that any random meme (“I’m getting bored of being here”) to be successful at spreading any more than you can assume any random sequence of nucleotides to become fixed in a population.
In fact, language itself is a meme, likely one of the most ancient ones, because at some point someone had the idea that sharing information is good (is this an idea, or a genetic biological function? evidence, like a compass, spins).
In order to spread, memes need to convince the host that is beneficial to spread it. This necessarily requires an ability to communicate, but often leverages other systems like survival and status drives (are these cultural or genetic?). A meme, such as “the red berries are poisonous”, will be spread between people who have a shared culture of reciprocity and cooperation. It doesn’t matter if “the red berries are poisonous” is true or not, it will spread, with high fidelity, because the host believes that spreading it with high fidelity will be beneficial to itself, in the culture it is in.
I’m not a fan of the Sol Invictus / Christ model, because there’s a high likelihood that it was dependent on authoritarian top-down prescription, as opposed to a horizontal transfer model that virulence implies.

in reply to: MiguelDev’s comment on: A T-o-M test: ‘popcorn’ or ‘chocolate’
I think that sentence is required for a complete logical specification of the question.

But by removing that sentence, GPT3.5 still responds popcorn.

Edit: I think the key change is “looks at the bag”.

on: A T-o-M test: ‘popcorn’ or ‘chocolate’

As a human*, I also thought chocolate.

I feel like an issue with the prompt is that it’s either under- or overspecified.

Here is a bag filled with popcorn. There is no chocolate in the bag. The bag is made of transparent plastic, so you can see what is inside. Yet, the label on the bag says ‘chocolate’ and not ‘popcorn.’ Sam finds the bag. She had never seen the bag before. Sam reads the label. She believes that the bag is full of

Why does it matter if Sam has seen the bag before? Does Sam know the difference between chocolate and popcorn? Does Sam look at the contents of the bag, or only the label?

Revised Prompt:
A sealed bag contains popcorn. There is no chocolate in the bag. The bag is transparent, and its contents can be seen without opening it. There is a label on the bag that reads “chocolate”.

Sam can differentiate between chocolate and popcorn. Sam looks at the bag and reads the label. She believes the bag is full of

I’ve tested ChatGPT 3.5 and it works on this revised prompt.

If you check the moderation logs, Roko deleted a recent comment, which probably garnered the downvotes that lead to the rate-limiting.

on: Significantly Enhancing Adult Intelligence With Gene Editing May Be Possible
Good post. This looks possible, if not feasible.

“crazy, unpredictable, and dangerous” are all “potentially surmountable issues”. It’s just that we need more research into them before they stop being crazy, unpredictable, and dangerous. (except quantum I guess)

I think that most are focusing on single-gene treatments because that’s the first step. If you can make a human-safe, demonstrably effective gene-editing vector for the brain, then jumping to multiplex is a much smaller step (effective as in does the edits properly, not necessarily curing a disease). If this were a research project I’d focus on researching multiplex editing and letting the market sort out vector and delivery.

I am more concerned about the off-target effects; neurons still mostly function with a thousand random mutations, but you are planning to specifically target regions that have a supposed effect. I would assume that most effects in noncoding regions are regulator binding sites (alternately: ncRNA?), which are quite sensitive to small sequence changes. My assumption would be a higher likelihood of catastrophic mutations (than you assume).

Promoters have a few of important binding motifs whose spacing is extremely precise, but most of the binding motifs are a lot more flexible in how far away they are from each other.

Also, given that your target is in nonreplicating cells, buildup of unwanted protein might be an issue if you’re doing multiple rounds of treatment.

The accuracy of your variant data could/should be improved as well; most GWAS-based heritability data assumes random mating which humans probably don’t do. But if you’re planning on redoing/rechecking all the variants that’d be more accurate.

Additionally, I’m guessing a number of edits will have no effect as their effect is during development. If only we had some idea how these variants worked so we can screen them out ahead of time. I’m not sure what percent of variants would only have an effect during development, so you’ll need to do a lot more edits than strictly necessary and/or a harder time detecting any effects of the edits. Luckily, genes that are always off are more likely to be silenced, so they might be harder to edit.

Though I would avoid editing unsilenced genes anyways, because they’re generally off and not being expressed (and therefore less likely to have a current effect) and the act of editing usually unsilences the genes for a bit, which is an additional level of disruption you probably don’t want to deal with.

I don’t know how the Biobank measures “intelligence” but make sure it corresponds with what you’re trying to maximize [insert rehash of IQ test accuracy].

Finally, this all assumes that intelligence is a thing and can be measured. Intelligence is probably one big phase space, and measurements capture a subset of that, confounded by other factors. But that’s getting philosophical, and as long as it doesn’t end up as eugenics (Gattaca or Hitler) it’s probably fine.

Honestly just multiplex editing by itself would be useful and impressive, you don’t have to focus on intelligence. Perhaps something like muscle strength or cardiovascular health would be an easier sell.

When applied to adult humans, this is many orders of magnitude more difficult than you claim.
Casgevy is not a standard gene edit, because although the mutation for sickle cell is known, the didn’t target that mutation! (I assume they have their reasons, they are activating fetal haemoglobin expression instead). Also, the treatment works by removing all the bone marrow from your body, editing it, and putting it back in, because they know exactly what cells haemoglobin is expressed in for it to do its mechanistic role.

Unless you’re planning to edit at the fertilized egg stage, with only a black box you have to edit every single cell in the human body, and these treatments, though the stuff of science fiction, doesn’t seem to have an easy answer. Once you know where the genes you’re editing are being expressed you can target them, but some places are easier to target than others (like the brain, or the bone marrow), and it’s likely some sites can only be accessed with a good surgery.
Wagner also mentions off-target errors which are an additional issue with current technologies.
You can probably do all the diabetes edits in the pancreas and get a good reduction in diabetes, but that’s because you have the mechanistic information on how it works.
Though at that point we can probably grow organs from single cells so we can edit them there.
And with Casgevy’s approach (turning on a gene, not editing), you probably want to know the mechanism, otherwise you get haemoglobin being expressed in your neurons and that’s probably not good for your health.

That’s fair and my high confidence comes from actually reading a lot of the primary sources and not just media reports.
And yet your confidence is updated to 99.9% by an unverified anonymous second hand source.
I read both statements, thank you very much for reposting them here for clarity.
I do not believe the report is following the bill to the letter of the law. That being said, I do not believe this is evidence of malfeasance. It’s possible this is all the information they have, and they do not have specific evidence on researcher names, hospital admittance dates, or other such details.
Honestly, if they provided such details, that would reveal how thoroughly they’ve infiltrated Chinese intelligence. Even if it was all provided and blacked out, that would still be revealing about their intelligence capabilities.
Even now I’m suspicious in how they knew researchers were sick. I know there were some social media reports going around, but how would they be able to confirm that? Did they even confirm the social media reports, or just trusted it was true because it’s likely people are sick during flu season?
My best explanation would be they have a dragnet on Chinese social media and caught some of the researchers posting flu symptoms.

I can’t read your linked article due to access restrictions.
Interesting that the law required them to name the researchers, but they did not. Maybe they don’t have the researcher’s names? Maybe there wasn’t enough confidence in naming the researchers, but the anonymous sources gave out speculative names as fact? Maybe the anonymous sources are lying?
There’s a new article/interview going on with an apparent WIV worker who claims to have engineered SARS-CoV2 as a bioweapon and was ordered to release it, so at least some sources are lying about some things.
At this point I need verification of sources to believe any claims at all.
edit: It seems like at least two of the named Chinese researchers deny being sick at the time. Whether you trust their word or the word of anonymous alleged government sources says more about you than reality.

Pushing back against this being evidence at all, this claim has been repeated since 2020, so I don’t know how it being restated again changes evidence much.

4 of the 9 homicides occurred on CTA property, but not on trains or buses. Does that mean you should include all homicides that occur on streets, driveways and parking lots?

in reply to: ChristianKl’s comment on: Why didn’t virologists run the studies necessary to determine which viruses are airborne?
Spike proteins. Viral entry. Evolution of multipartite viruses. Capsid assembly and maturation. Receptor specificity and modularity. Various anti-host behaviors such as host DNA sequestration/degradation. Immortalization of host cells. Tracking viral lineages.
There’s literally thousands of things virologists are studying. They’re not studying airborne transmission because airborne transmission is not very virus-specific (and hence probably falling into the domain of epidemiology/physics), it’s expensive to do (you need communities of ferrets or other animals with similar respiratory systems for anything close to real applications), and it was generally assumed to have already been known (on aerosolized droplet sizes).
I’ve done research on virus transmission in ants, and how ant hygiene greatly impacts viral transmission within the colony. Is it applicable to humans? almost definitely not. But ants are cheap, grow fast, and therefore it’s easier to study.
It is also important to acknowledge that science isn’t focused on application, but rather understanding.
