  • Nuclear rocket engines. A bit less ambitious than most of the responses, but most things here seem to either refer to technologies we don’t have yet but seem within a century or so of developing, which doesn’t fit the question, or vague consequences that one wants that tech to have without it being clear how our current technology gets there. But nuclear rockets definitely fit the question, because we have built and ground tested them before, decades ago even, we just haven’t bothered to actually use the things. And they should theoretically make developing things like space industry or manned space exploration beyond the moon more viable, by being more efficient than chemical rockets while giving better thrust than ion engines do. They don’t work well for launching from the ground, but since our launch abilities have increased a fair bit in the past decade or so, actually getting the things to space in order to use them should be easier than ever.






  • I tend towards a variation on utilitarianism, from that point of view energy in a finite universe that could be used to support intelligent life in some way, but isnt, is unethical, and while that might not really demand much action from us right now given that space development is a very, very long term project by nature and we’re already working on developing the most basic forms of the requisite technology, it still seems a bit frustrating to lose that which we cannot reach. Its not just us either, statistically speaking it should be extremely unlikely for life and advanced intelligence to occur once, but only once, so I take it as a given that theres more out there somewhere, but evidently it cant be that common or else hasnt gotten much further than us, given all the stars we can see out there.

    I dont really think everything we touch turns to shit, I just think we judge ourselves much more harshly than we judge “natural” things. I dont really care that much if the people that go off to the stars do so because of some desire to harvest them for some kind of profit or put up a space-mcdonalds at alpha centauri or whatever, as long as someone goes. Obviously I would prefer they build a nicer society there than just a rehash of what we have here right now, but in my view even the crappiest society is preferable to a dead rock or inanimate clump of gas, even if it is an aesthetically pleasing rock. Beauty is in the eye of the beholder as they say, and I think we can make beautiful things, or failing that, and least find the beauty in what we do make, if we try.



  • Im not sure that financial literacy can really be called fighting the power structure tbh. Like, sure, certain companies that make money off debt might make less off you, but for a person that isnt rich, the money saved is gonna end up spent on something else at some point, so every other company except the ones selling debt benefit from you not being in it. If anything, citizenry that are so broke that they cant buy things and struggle to survive are less able to contribute to a consumer economy and might require the government either spend more money on social services so that they can keep stable enough to work, or spend more money on policing to deal with the increase in crime that comes with desperation.



  • While I don’t think this scenario likely, something that I can’t help but thinking when this sort of statement comes up is, well, how do we know what it’s doing isn’t thinking? Like, I get that it’s ultimately just using a bunch of statistics to predict the next word or token or whatever, but my understanding was that we have fairly limited knowledge of how our own consciousness and thinking works, and so I keep getting the nagging feeling of “what if what our brains are doing is similar somehow, using a physical system with statistical effects to predict stuff about the world, and that’s what thinking ultimately is?”

    While I expect that it probably isn’t and that creating proper agi will require something fundamentally more complicated than what we’ve been doing with these language models and such, the fact that I can’t prove that to my own satisfaction makes me very uneasy about them, considering what the ethical ramifications of being wrong about it might be.






  • I’ve recently come to the position that really, there isn’t truly such a thing as incorrect grammar. There’s grammar that doesn’t fit the norm for the people one is speaking to, and if it’s different enough to impair the ability for the intended audience to understand what you’re communicating it can be impractical or inadvisable, but since grammar isn’t an intrinsic part of the universe outside of human creation, and since the way it’s used changes whenever people “break it’s rules” in numbers over time, it can’t actually be wrong. After all, someone could view something written in a very closely related foreign dialect as another similar language written correctly, or one’s own language written incorrectly, and there isn’t really a non-arbitrary way to decide which is the case.



  • The traditional notion of a Dyson sphere/swarm isn’t using the thing to power earth, or launching the construction materials from earth for that matter. You would literally deliver enough power to overheat the planet that way.

    The idea is that you mostly live in space habitats by that point, so a given solar array is just powering the habitat it’s attached to, or one nearby (or for one farther out, you can have some satellites that are just big, thin foil mirrors that focus sunlight from a wide area onto a solar array). You probably build these from asteroids and such, since again the energy cost to launch material from earth is prohibitive. A bit like how it would be cost prohibitive for a single city on an empty planet to engage in a project to colonize and build new farmland and cities across the entire world: they wouldn’t actively build with that goal in mind, so much as they expand a little bit, and a bit more with the surplus gained by that expansion as the population grows, until one day their descendants run out of empty land to expand to. A Dyson sphere is just the end state of this for a solar system rather than a planet.

    It probably does take thousands of years, or more, and a corresponding level of effort, but that’s nothing compared to the life of a star, so if you have a species that’s got the technology to build a civilization in space, they have the time.
