Comment Fascinating! (Score 1) 32

Now, yes, there are predictions that you could get a supermassive black hole launched into space, especially during a galaxy merger if the velocity of the smaller black hole exceeds the escape velocity of the combined galaxy.

But I'd be wary of assuming that it's a launched black hole, unless we can find the merger it comes from. There may be ways for such a black hole to form that cause the stars to be launched away rather than the black hole being flung, and if a galaxy isn't rotating fast enough to be stable, one could imagine that a sufficiently small galaxy was simply consumed by its central black hole. Both of these would seem to produce exactly the same outcome, if all we have is the black hole itself and a velocity.

I'm not going to say either of these is likely in this case, or that astronomers haven't examine them (they almost certainly have), but rather that we should be cautious until we've a clearer idea of what the astronomers have actually been able to determine or rule out.

That doesn't make sense. Electing one person has to be "winner takes all" and the head of state pretty much has to be one person. "Pretty much" because things like bi- and triumvirates are occasionally tried but they usually end badly. That happened in the US actually, where the runner up for president used to become vice president.

The real problem in the US is that the head of state is so dominant. Their legislature is highly partisan and members are very much subservient to their party leadership, which more and more includes the president. Because of that, plus all the pomp around party elections, both the presidency and the legislature degenerate into a two-party system.

Most democratic countries have addressed the issue by making the head of state purely ceremonial, as in Westminster parliamentary systems, not very powerful (most of Europe) or powerful but at least not a part of the government (France since 1958, we'll see if they got it right this time).

The electoral college, that quaint 18th century backup method for rich Americans to rig presidential elections, is a side issue.

Americans aren't hopeless. They've just lived for a couple hundred years under some slave-owning import/export operators' amateur alpha build of Democracy (with a capital D because America) that they had to come up with in an emergency because the king took their little tax revolt more seriously than they expected.

It turns out there were some bugs but unfortunately one of the bugs affects the revision process. Some of the other bugs affects the process by which new Americans are turned into voters. And many of those bugs are actually considered features by import/export operators who at least have to be more subtle about their slave-owning.

The characterization of "risk of artificial intelligence overpowering humanity" as the substance of an 'AI debate' seems itself like a strategy in trying to forestall it.

Sure, there's some fun sci-fi there; but most of what actual people are actually concerned about is what specific parts of humanity are using 'AI' to do, or justifying doing in the name of 'AI'; not fretting about how skynet might kill us all. And it's exceptionally handy to pretend that that is what people are fretting about; both because it's a distant and vague enough problem that you can justify punting most action without even lying; and because it's not even false that (perhaps outside of a handful who have outright cracked and started thinking about it in religious terms) even the most psychopathic techbros are also against skynet exterminating everyone; both because that would include them; and because Judgement Day would not be a good time for social media engagement metrics.

Yeah, when thinking of the typical air fryer market, think "working mom with kids who wants to serve something nicer than a microwave dinner, but doesn't have the time for much prep or waiting". You can get those mailard reactions that microwaving doesn't really get you, nice crisping and browning of the surface that you normally get from an oven, without having to wait for an oven to preheat. I don't think anyone disputes that an oven will do a better job, but the air fryer does a better job than a microwave, which is what it's really competing against. They're also marketed as easy-clean, which again is a nod to their target audience.

How costs build up is really staggering. I'm getting into the business of importing 3d filament. In Iceland, it currently sells for like $35/kg minimum. The actual value of the plastic is like $1. The factory's total cost, all costs included, is like $1,50. If it's not name brand, e.g. they're not dumping money on marketing, they sell it for $3 for the cheapest stuff. Sea freight adds another dollar or two. Taxes here add 24%. But you're still at like $5/kg. The rest is all middlemen, warehousing, air freight for secondary legs from intermediary hubs, and all the markup and taxes on those things.

With me importing direct from the factory, sea freight only, I can get rid of most of those costs. Warehousing is the biggest unavoidable cost. If I want to maintain an average inventory of like 700kg, it adds something like $5/kg to the cost. Scanning in goods and dispatching user orders (not counting shipping) together adds like $2,50. And then add 24% tax (minus the taxes on the imported goods). There's still good margin, but it's amazing how quickly costs inflate.

I'm sure that serving you a lot of ads is the point of the excessive length of internet recipes, but there's another reason, too. A simple list of ingredients, or a list of instructions (like how to build Ikea furniture) cannot be copyrighted. I think many of these overly verbose recipe authors really do want to make it appear that their own takes on the recipes are distinct and innovative, and that helps them secure their own content from being scraped wholesale. But of course, AI just says, "fuck it, I can summarize," and it's pretty hard to prove it was your recipe it summarized..

I mean, from a horticultural perspective, there is some potential to gain more of other nutrients, in that if you have more energy, you can develop a larger root system, or generally more effectively, better feed mycorrhizal associations (fungal hyphae are much finer than root hairs, so can get into smaller cracks, and fungi can "acid mine" nutrients out of mineral grains - as an example, here's a microscopic image showing what they did to a garnet)

That said, yeah, in general if you can provide more energy, you expect the storage of "calories" to grow much faster than the acquisition of other minerals. Also, it's important to note that while more CO2 is generally good for most plants, more heat, or greater periods of drought (land dries out faster, monsoon belts spread) and flooding (atmosphere holds more moisture, monsoon belts spread) are not. In regards to heat as well, there's a lot of details. First off, though we commonly don't think about it, heat management in plants is critical. Their proteins are designed for function within an optimal temperature range, and to maintain it, they have to cool themselves down with transpiration, creating more water stress. Also it's worth noting that C3 plants (most plants) fundamentally don't tolerate heat as well as C4 or CAM plants (there's work to engineer C4 into some common agricultural crops... it's frankly amazing to me that they're getting some success, as it's not a trivial change).

BTW, the reason that plants grow better with more CO2 isn't what most people might think. The TL/DR is that the protein that sequesters CO2 so that (using ATP and NADPH from photosynthesis) - RuBisCo (the most abundant protein on Earth, something that has been evolving for billions of years) frankly sucks at its job. Something like 20-25% of the time (at normal CO2 levels), instead of binding with CO2, it binds with O2 instead ("photorespiration"), which means not only does it not sequester a carbon, but the plant has to *give up a carbon* to regenerate the RuBisCo. This is disastrous in terms of energy efficiency. And as a side effect, you also have to keep the stomata open more, which means more water loss. But as you increase the CO2 levels, the ratio between binding CO2 and binding O2 improves, and photorespiration waste drops. C4 plants "fix" this problem by instead of having RuBisCo directly bind CO2, they first bind CO2 into malate (with high selectivity), then the malate transports into bundle sheath cells, the CO2 is re-released, and THEN - in a high-CO2 environment - RuBisCo takes it up. This reduces photorespiration, but also introduces some more wasteful chemical conversions. (CAM plants to even further by storing malate inside vacuules - at the cost of even more energy - so that they can store it up during the night, and then use it during the day, which - although even more wasteful - lets them keep their stomata closed during the day to conserve water)

(BTW, there are some microbes that have developed a more efficient RuBisCo, but it's proving challenging to engineer it into higher plants)

So, what would be wrong with an actor or actress selling their scanned image WITH contractual obligations to be PAID whenever the image was used in a film or when used as source to generate a new digital actor?

Wouldn't continuing pay and residuals help make the argument here?
