  • I believe that’s not the law though. The law outlines the conditions under which a person has an “expectation of privacy.” If you’re inside your house, you have an expectation of privacy and so should not be filmed. If you’re on the sidewalk in public, you have no expectation of privacy. If you’re in a private establishment (restaurant or store for instance), the owner or their representatives can ask you not to record and you have to comply.

    All of street photography depends on this kind of legal framework.


  • Theoretical biologist here. I consider viruses to define the lower edge of what I’d consider “alive.” I similarly consider prions to be “not alive,” but to define a position towards the upper limit of complex, self-reproducing chemistry. There’s some research going on here to better understand how replication reactions (maybe encased in a lipid bubble to keep the reaction free from the environment) may lead to increasing complexity and proto-cells. That’s not what prions are, but the idea is that a property like replication is necessary but not sufficient and to build from what we know regarding the environment and possible chemicals.

    I consider a virus to be alive because they rise to the level of complexity and adaptive dynamics I feel should be associated with living systems. I’ll paint with a broad brush here, but they have genes, a division between genotype and phenotype, the populations evolve as part of an ecosystem with all of the associated dynamics of adaptation and speciation, and they have relatively complex structures consisting of multiple distinct elements. “Alive,” to me, shouldn’t be approached as a binary concept - I’m not sure what it conceptually adds to the discussion. Instead, I think it should be approached as a gradient of properties any one of which may be more or less present. I feel the same about intelligence, theory of mind, and animal communication.

    The thing to remember when thinking about questions like this is that when science (or history or literature…) is taught as a beginner’s subject (primary and secondary school), it’s often approached in a highly simplified manner - simplified to the point of inaccuracy sometimes. Many instructors will take the approach of having students memorize lists for regurgitation on exams - the seven properties of life, a gene is a length of dna that encodes for a protein, the definition of a species, and so on. I don’t really like that approach, and to be honest I was never any good at it myself.


  • No, computer engineering tends to focus more on hardware. When I was doing that kind of thing in college, computer engineering did things like chip design and logic boards and so on. I had courses on DSP and VLSI, multiple assembly languages, RISC vs CISC systems, and so on. In my university, it was considered a subspecializqtion of electrical engineering, with the first two years of undergraduate study being identical.

    When I switched over to CS, I was doing things like numerical analysis and software systems architecture.

    Both majors used math, but CE (as an EE major) required students to go through (iirc) calculus 5, and I think that CS majors could stop at calc 3 but would end up having to do different kinds of math after that.


  • I’m a theoretical biologist.

    The best book I read on multilevel selection theory was actually written by a professor of philosophy. The author broke down the individual concepts, as they do, so that anyone reading it knew exactly what each technical term referred to. Biology is my favorite subject because there’s so much that we’re still figuring out and it’s just ridiculously complex.

    I might have had a similar hot take as an undergrad when everyone has an ego based on their major - and I was even a computer engineering student for awhile, and engineers tend to be even worse at that sort of thing.









  • Probabilistic curves are pretty much the opposite of what we normally mean when we say “free will.” If the assumptions were correct, we’d tend to use the term “non-deterministic.”

    I tend to lean in the direction of Stanford neurobiologist Robert Sapolsky who believes that it is deterministic but not predictable due to the complexity of the parts and their interactions.


  • This is known as the Whorfian Hypothesis, aka Sapir-Whorf theory. In generalized-to-the-point-of-inaccuracy terms, the idea is that language constrains thought. It’s one of those ideas that we can perceive as intuitively correct but that does not stand up to experiment.

    There are, for example, languages that don’t have words differentiating green and blue, and others whose counting numbers don’t include specific words for numbers larger than two. Some languages have no words for cardinal directions but use terms like “mountain-way” and “ocean-way.”

    Experiments do seem to support a weak version of Whorf - people from cultures with “missing” words can differentiate between green and blue for instance, but it seems to take a bit longer. There’s also a paper indicating that people who don’t use cardinal coordinates have a better innate sense of orientation when, eg, walking corridors in an enclosed building.

    I’d personally fall between the weak and strong position because I do not believe in free will and do believe that semantics are a significant driver of behavior, but that’s a step beyond where most of the current research is. There’s research into free will, but none that I’m aware of that pulls in cognitive semantics as a driver.


  • I don’t see a future utopia (or non-utopian) society a thousand years from now feeling at all compelled by a legal agreement between two independent parties a millennium ago. The law firms that set up the contracts will be long gone, the legal framework that established them will have evolved if not been replaced completely. I mean, compare where we are now with where “we” were in 1024, and then think about how much more quickly things change today. Any money is going to be more meaningless than 11th century money, but with no collector’s value since they’re just numbers in a database that probably won’t even exist in a thousand years.

    I think we can legitimately view having your body/head frozen in the hopes of being woken up as a tech version of the Catholic last rites.


  • Cool! There’s probably a small factor differentiating the two, but it’s not that noticeable.

    I did a research project looking at (iirc) kinase cascades, in which we were using a molecule-by-molecule simulation to look at cascading signals in hypothetical signaling networks, and varied the levels of phosphorylation required for activation required at each tier, and showed how the different topologies/rules governed the relationship between input and output signals, and their relationship to noise tolerance (since chemical networks can be quite noisy). It was very abstract in that we weren’t reconstructing known networks, but rather using sandbox physics to explore the idea.




  • There’s entire branches of research on this, but I think one of the easiest ways to approach it for starting out is to think of the word “womanly.”

    having or denoting qualities and characteristics traditionally associated with or expected of women.

    I would strike the word “traditionally” from that definition since we’re talking about a comparative and differential analysis and concentrate on the “qualities and characteristics” part. Although most people in the US today wouldn’t think of it this way, imagine the perception of a woman army officer commanding male troops in 1845. You can take the same approach when looking through history or across cultures. What roles, qualities, and characteristics are associated with “women” and how do they differ and evolve?

    There’s some complexity when you get into the details - indigenous cultures change when they come into contact with, say, colonialism, and the people who studied them might themselves be observing through their own prejudices. History is replete with examples of British colonialists being unable to properly deal with things like the egalitarian democracies of the northern indigenous peoples or the matriarchal social structures. Picture the used car dealership where the salesman still insists on engaging with the man even though it’s the woman buying the car.

    Semantics is the study of the meaning of words, and semiotics is the study of symbology. When we’re talking about these things, we’re talking about how the ideas and symbols associated with the idea-token “woman” differ.

    The reason why this is important is that this is the crux of the transphobic argument. Their argument is cultural, not biological (although like I said, even their biology is sketchy).

    I think a great study that includes cross cultural anthropological analysis of the role of women, as well as politics and economics, is David Graeber’s The Dawn of Everything.


  • Biologist here. The main problem with this argument is that Rowling is trying to win her argument through scientizing, and is not only doing it in an inept way, but in a way that’s completely ironic.

    She’s invoking biology, but infortunately she’s adopting an approach that incorporates a high school level of biology. When we start teaching science, we start with highly simplified presentations of the major topics, then build both in breadth and depth from there. If you really want to get down the rabbit hole of sex determination (and multiple definitions of genetic and phenotypical “sex”), you really need to get into molecular biology, genetics, and developmental biology. She’s been advised of this multiple times by multiple experts, so at this point it’s willful ignorance.

    The painfully ironic part is that she’s relying on an area where she has no expertise in order to make her point, while ignoring the fact that, as a world-known literary figure, she should know that the applicable part of the definition of “woman” is linguistic and semiotic - which is to say it’s cultural. The definition of “woman” was different in the 1940s South, among the 17th century pilgrims, the Algonquin tribes, cultures throughout sub-equatorial Africa, and so on.


  • It strikes me as exactly the kind of engineering call that Elon has tended to make, time after time. With zero training in an area, he gets a solution in his head crufted up from some set of pre-existing notions or points of view and then pushes to have them implemented. He will also go on to fire anyone who disagrees with him. I spoke with an engineer who worked on the gull wing doors, which the team had objected to, and not only did he force them through, he burst in on one of the finalization meetings where they had finally reached a design consensus and insisted they change the hinge. Given similar reports on his behavior regarding other products (including especially twitter), I have no reason to disbelieve this person.
