AGI Alignment – Cosmic vs Anthropocentric
  • I'd say having some kind of goals is definitional in AGI, so in a broad sense of "alignment" that would include "paperclip optimisers", sure, it's bound to be possible. Natural GI exists, after all.

    Speculatively, if you allow it to do controversial things some of the time, my guess is that there is a way to align it so that the average person will agree with most of the time. The trouble is just getting everyone to accept the existence of the edge case.

    The versions of utilitarianism usually give acceptable answers, for example, but there's the infamous fact that they imply we might consider killing people for their organs. Similarly, deontology like "don't kill people" runs into problems in a world where retaliation is usually the only way to stop someone else violent. We're just asking a lot when we want a set of rules that gives perfect options in an imperfect world.

  • Mercedes-Benz says its testing solar power generating vehicle-paint that could coat vehicles, and generate 100% of their power requirements in sunny cities like Los Angeles.
  • "They" here was you. You did the math. That was a bit ambiguous, sorry.

    Journalistic misunderstanding is possible, I guess. There's no way it's just a wire to the high-voltage motor output - it doesn't trickle charge off the grid directly either - although omitting the charging system is arguably more of a wording choice.

    Here's another one where they go into more detail, and even mention the possibility of perovskites independently: https://newatlas.com/automotive/mercedes-benz-solar-paint/

    Unfortunately the press release itself doesn't seem to be accessible, after a quick search.

  • Mercedes-Benz says its testing solar power generating vehicle-paint that could coat vehicles, and generate 100% of their power requirements in sunny cities like Los Angeles.
  • Well, "they did the math". If you read the article, they're saying 32km/day in Stuttgart and 47/day in LA, and then extrapolating to 55/day in Australia. This is from their practical trials.

    The kicker to the kicker is that they are claiming >20% efficiency here. It's apparently a very revolutionary new paint. The main thing they didn't cover is how fast it degrades, which has been a huge problem with perovskite-based systems like I bet this is.

  • Which of the World's Richest People Inherited Their Wealth?
  • They borrow themselves as a way of dodging US taxes, which might be what you're thinking of.

    Holding bonds is the obvious way all of these people would probably be doing the sin of riba. It's not necessarily public information, though. (And you can invest in bonds too; there's no secret money glitch, just a societal lottery that someone will inevitably win)

  • Which of the World's Richest People Inherited Their Wealth?
  • That's a good point. Charlie III is so hereditary it's his whole brand. It looks like he might not actually have a billion, though, just most of one.

    I'm not sure if any other European Royal families might have managed to retain more.

  • Wealth of the World’s Billionaires Has More Than Doubled Over the Past Decade
  • Yeah, it's a continuous scale, which is something people miss sometimes. When you talk to people with millions of dollars they have a tendency to say they're not that rich, and point to some guy they know with tens of millions. They're not wrong per se even if they're dangerously out of touch; that extra digit changes a lot.

    The bullshit is just that that scale goes way, way too high, as well as way too low. Human ability is normally distributed, and human worth is often held to be inalienably equal. Wealth follows a completely different distribution, for reasons.

  • Has there ever been a case where a kidnapee was able to brainwash his captors into freeing him/her?
  • A good guess. I'm not sure how Evangelical he is, but he sounds like a fellow traveler having worked with Reagan and inflicted abuse on people from other faith groups.

    I said a Christian author just because most people are over the Protestant vs. Catholic thing, and Chinese communists are a particular favourite bugbear of theirs.

  • Truly, barley is a terrible fate
  • PugJesus could probably go into more detail, but it was a very rare and extremely serious punishment - partly or mostly because they were the ones that had to beat their own buddies to death.

    Barley and normal corporal punishment were more like the everyday fare. The past was a brutal place, but in a lot of ways normal life is normal life no matter when.

  • The wonders of English spelling
  • Not necessary. You can "have your cake" and eat it with spoons of both Aluminum and Aluminium, too. It just has to reflect spoken sounds in some kind of reasonably-direct way.

    Hmm. Do Brazilians still spell stuff the Portuguese way? Most of the European languages probably have some kind of prescribed national dialect, Arabic has classical Arabic, and Chinese has non-alphabetic characters, but I don't know about that one.

  • The wonders of English spelling
  • I've seen enough French spelling to get it, though, and I don't really speak French. English spelling is still often hard as a native speaker.

    You guys can have second place, our system is the most ass "bar none".

  • Has there ever been a case where a kidnapee was able to brainwash his captors into freeing him/her?
  • There's a history of it meaning some kind of magical personality replacement thing, though. IIRC it was a Cold War excuse for why US soldiers defected sometimes. Cults exist, but the techniques they use to pressure people are a lot more mundane and take time to really take root.

    Edit: Yup. More info here.

  • Wealth of the World’s Billionaires Has More Than Doubled Over the Past Decade
  • Two options, if you're shilling for billionaires:

    They're intrinsically 10,000x better than you and me and deserve to be 10,000x richer.

    It's just theirs. It says so somewhere, no backsies.

    Pure trickle-down had it's day too, but it's it's a joke again in modern times, for the most part. You may object that these are all weak arguments, but basically, you and what army?

    Edit: "We need a remote chance of becoming a billionaire for anyone to go to work" is kind of a blend of trickle-down and argument number one, but I suppose I should mention it, just for the sake of completeness

    Heart cockle shells transmit sunlight to photosymbiotic algae using bundled fiber optic cables and condensing lenses - Nature Communications

    www.nature.com Heart cockle shells transmit sunlight to photosymbiotic algae using bundled fiber optic cables and condensing lenses | Nature Communications

    Many animals convergently evolved photosynthetic symbioses. In bivalves, giant clams (Cardiidae: Tridacninae) gape open to irradiate their symbionts, but heart cockles (Cardiidae: Fraginae) stay closed because sunlight passes through transparent windows in their shells. Here, we show that heart cock...

    I considered posting this elsewhere, but only Canadians are really going to get why it's funny. Regina being totally self aware about it's (lack of) reputation made it for me.

    www.bbc.com Netanyahu not doing enough to secure Gaza hostage deal, says Biden

    US president says he is 'very close' to presenting proposal to free remaining hostages as Israelis protest over latest deaths

    Netanyahu not doing enough to secure Gaza hostage deal, says Biden

    Per the rules, this is the original headline. However, the interesting part is that he's preparing a Gaza offer that he says will be "final".

    They've hewn very close to the whole "unconditional support" thing, so I'm curious what that means exactly.

    How do you find the center of two concentric circles with just a straightedge?

    The Wikipedia article on Steiner constructions mentions it, but doesn't explain it, and the source linked is a book I don't have. This has come up in a practical project.

    Is there a precedent for a really delay-tolerant command line interface? (A bit off-topic)

    I've been playing with an idea that would involve running a machine over a delay-tolerant mesh network. The thing is, each packet is precious and needs to be pretty much self contained in that situation, while modern systems assume SSH-like continuous interaction with the user.

    Has anyone heard of anything pre-existing that would work here? I figured if anyone would know about situations where each character is expensive, it would be you folks.

    We have no idea how many there are, and we already know about one, right? It seems like the simplest possibility.
