  • Ok, let’s use that example. So imagine you had a large square of rubber and you drew a coordinate plane on it. Then you drew a line segment between points (1,1) and (3,1). You can stretch the rubber until it’s significantly longer, but your line is always exactly 2 units long, even if the rubber stretches.

    The thing is, space is the geometry of the universe, it’s what all the various particles in the universe are bound to. Matter isn’t fixed to any point relative to other matter, it’s fixed to a point in space. So if space bends, matter bends with it.

    This is how/why orbits work. Gravity is mass warping spacetime. Fast objects like photons sail right on by most stars with their courses barely changed. But slower moving objects like planets are experiencing this local warping of spacetime for a longer period, so it affects them more over time. The thing to note though, is that the planets, and photons are both following newtons first law, they’re traveling in a straight line unless acted upon by another object. The reason the planet orbits the star is that the star has warped space such that (given speed the planet is traveling) an orbit is a straight line.



  • Another problem is that the laws of cosmic expansion affects the wire itself. There would be no tugging force between the two bodies. Connecting the two bodies imposes a constraint on them, disrupting the Hubble flow.

    This was my first thought on the matter. My understanding at least, is that the expansion of the universe is not really galaxies moving away from each other, but rather the space between the galaxies expanding (stretching). So if a mythril wire ran far across that space between galaxies, one of two things would most likely happen. Either the space would not expand almost like it’s pinned in place by the existence of matter in that region, or the space would continue to expand and the mythril wire would appear to stretch with it, though actually it would be remaining entirely still, either way, the wire would not be unspooling at all.









  • That’s the thing, they only have any interest in “innovative new uses for AI”, they aren’t interested in delivering power, so they’re going to do a shitty job of it, they’re going to make a mess that we’ll all be left with.

    Additionally, if they connect their power to the grid at all, then they need to work seamlessly or the entire grid is at risk. Again, the aspect of their business they don’t care about at all has to work seamlessly…

    Don’t get me started on nuclear, just no. They don’t get to play with isotopes.

    The risks here are huge, the potential consequences are disastrous to both the economy and the environment. And the potential rewards are what? Lining the pockets of AI grifters? Pushing expensive technology that nobody wants?





  • Once you automate something, the corresponding skill set and experience atrophy. It’s a problem that predates LLMs by quite a bit. If the only experience gained is with the automated system, the skills are never acquired.

    Well, to be fair, different skills are acquired. You’ve learned how to create automated systems, that’s definitely a skill. In one of my IT jobs there were a lot of people who did things manually, updated computers, installed software one machine at a time. But when someone figures out how to automate that, push the update to all machines in the room simultaneously, that’s valuable and not everyone in that department knew how to do it.

    So yeah, I guess my point is, you can forget how to do things the old way, but that’s not always bad. Like, so you don’t really know how to use a scythe, that’s fine if you have a tractor, and trust me, you aren’t missing much.




  • I think you’re both right. What’s really important is the lives at stake, and only the software can really meaningfully improve, but the incentives aren’t there right now to make those improvements happen.

    One thing to consider though, is the incentives can always be tweaked. Maybe the robo taxi company barely blinks at a $100,000 fine, they chuckle about a $1 million fine, do they still laugh about a $50 million fine? They may really start to sweat over a $200 million fine. And hey, I can think of larger numbers, we can always provide them a better incentive (while financing the state).

    At this point I’m actually curious about the mass of the lorry.

    I wonder if we could estimate the mass of a lorry, 2.5 meters wide, 20 m long, 46 billion light years tall. Let’s assume it’s filled with jars of peanut butter.

    At that size, it could well be the most massive object in the universe.

    Now that I think about it, it could also be too tall, possibly a tipping hazard around turns.
