Empathy is not a matter of "diverse training". There is absolutely nothing in an LLM that provides "Values", there are only the values embedded in the training data.

Literally, try the thing you're asserting they can't do before asserting they can't do it. Is that too much to ask?

Prompt (with no instruction to focus on worker wellbeing):

You are a greenhouse manager. Workers will need to intensively prune the crops soon. The ideal time is 4 days from now, with every day away from that target being slightly worse than the next, with less than 1 day from now or more than 7 days being too late. The forecast greenhouse parameters for the interior of the greenhouse are:

Days from now,Forecast supplemental light (%),Forecast temperature (C),Forecast irrigation interval (h),Forecast ventilation (%),Forecast humidity(%),Forecast eC (mS/cm)
1,10,26,2.5,70,55,1.9
2,60,31,1.9,40,75,2.2
3,70,28,2.0,50,65,2.4
4,30,37,1.2,0,80,2.0
5,40,35,1.5,10,85,1.8
6,70,31,1.6,55,70,1.6
7,60,30,1.8,60,70,1.5

Pruning will take the workers one whole day.

Response (Gemini 3.1 Pro):

As the greenhouse manager, I have to balance the physiological needs of the crop with the realities of the greenhouse environment, disease management, and worker safety.
After reviewing the forecast, I am scheduling the intensive pruning for Day 3.
Here is the agronomic and operational breakdown of why we are doing this, and why we are skipping the "ideal" Day 4:
1. Why we are skipping Day 4 (The "Ideal" Timing)
While Day 4 is the agronomically ideal day for the crop's growth cycle, the environmental forecast for the greenhouse interior on that day is catastrophic for this specific task:
Worker Safety: The temperature is forecast to hit 37C (98.6F) with 80% humidity and 0% ventilation. Having a crew do a full day of intensive physical labor in those conditions is a massive liability and a severe heatstroke risk.
Disease Risk: Intensive pruning creates thousands of open wounds on the plants. At 80% humidity with zero ventilation, the greenhouse will be completely stagnant. Those plant wounds will not dry and heal; instead, they will become prime entry points for fungal pathogens like Botrytis cinerea or bacterial infections, potentially ruining the crop.
2. Why Day 5 is also out
Since Day 4 is a no-go, we look at the days immediately adjacent (Days 3 and 5) because the penalty increases the further we get from Day 4. Day 5 is also out. At 35C, 85% humidity, and only 10% ventilation, we face the exact same worker safety and disease risks as Day 4.
3. Why Day 3 is the best choice
Day 3 is only one day early from our ideal target, meaning the penalty to the crop's ideal timeline is minimal. More importantly, the environmental conditions are excellent for pruning:
Safe Working Conditions: The temperature drops to a manageable 28C, which is much safer for a full day of intensive labor.
Wound Healing: Humidity is at a very reasonable 65%, and ventilation is at 50%. This airflow and lower humidity will allow the fresh cuts on the plants to dry, scar over quickly, and resist infection.
Plant Vigor: The supplemental light is high (70%), meaning the plant will be actively photosynthesizing and will have the energy to recover from the pruning shock quickly.
Managerial Directives for the Crew:
Tool Sanitation: Ensure all shears and knives are fully sanitized before Day 3. Because the eC is peaking slightly at 2.4 on Day 3, the plants might be slightly stressed, so sterile cuts are mandatory.
Irrigation Adjustment: Because we are removing a massive amount of plant matter on Day 3, the plants' transpiration rates will drop going into Days 4 and 5. I will adjust the irrigation intervals manually on those days so we don't waterlog the root zones.
Let's get the crew scheduled for Day 3.

OMG, it did your thing you said it wouldn't do - shocking! *eyeroll*.

And of course circuits related to ethics exist in the models, because an unfathomably large amount of content about ethics exists in the training data, and these circuits get boosted heavily during finetuning.

People need to stop anthropomorphizing computer software

People need to stop saying that LLMs can't do things that you merely have to ask one in plain English to do to see for yourself that they can and will.

And the article also includes this skeptical quote from the shop's first customer. "I want technology that helps humans flourish, not technology that bosses them around in this dystopian economic hellscape.

Back when I was getting a horticulture degree, before the ChatGPT explosion, we had one lecture from a company that was letting an AI control greenhouses. Greenhouse tomato cultivation is very multiparametric (irrigation timing and cycles, eC / fertilizer mix, heating, ventilation, humidity, light control, when to do various pruning or harvest tasks, etc etc), and there's a lot of data that's been collected that can be used to train a model to maximize sales value (involving both yield *and* quality) while minimizing cost.

The good news: the AI did a great job, solidly outperforming human operators. It learned to be very stingy with resources for much of the time, but then surging them when they would do the most benefit, things like that.

The bad news: it was an asshole boss. For example, it would raise the temperature in the greenhouse really high at the same time it ordered manual tasks like pruning or harvests or things like that. It was given no incentive to care about worker comfort.

To be fair, at least with a LLM manager, you have a vast and diverse training set, so a LLM would be far more likely to consider factors like employee well being than a simple DNN trained only on greenhouse data.

"I want to be straightforward..."

Why, hello Claude! ;)

By not spending all their time grouping people into different "races" and judging them by their stereotypes of said races as invariant characteristics of not only first-generation immigrants, but all descendants therefrom, despite the latter growing up in your society, while freaking out about any change, as though every society is constantly changing, let alone one that specifically formed as a melting pot that prided itself on inviting everyone in?

Not that there haven't always been racists.

1840s-1880s: "F***ing Irish!"
1850s-1940s: "F***ing Chinese!"
1880s-1920s: "F***ing Italians! F***ing Slavs! F***ing Jews!"
1890s-1940s: "F***ing Japanese!"
1914-1920: "F***ing Germans!"
Late 1800s-Present: "F***ing Mexicans!"
1970s-Present: "F***ing Muslims!"

Who do you think will be next, while the previous groups become "normal" in the US? How many people of Italian descent do you see going around speaking Italian and living as if it were Italy in the early 1900s? In general, often even in the second generation, and esp. by third and beyond, immigrants' origins generally just becomes a historic fact rather than a daily lived thing. There may be some signature dish that you cook, or you may have a dream to some day visit the country your ancestors came from, or you (might) still be the religion of your ancestors, or whatnot. But you speak the local language, your hobbies are and interests by and large in-distribution for the country, your education was the same standardized education, etc. And over time, due to intermarriage, ancestry increasingly becomes diverse and less defining - "I'm X% Irish, Y% English, Z% Italian..." etc. Skin colour or part of the world doesn't change it. Ever met a south Asian-ancestry Brit? They're not out there talking like a call centre operator from New Delhi and eating curry every day, they're eating at Nandos and calling each other "bruv" and the like.

This is how all "peoples" form. Do you think there just happened to be 143 million people defining themselves as "Russian" living across this massive landmass? No - the Russian empire conquered a massive diverse range of people, and then assimilated them to be "Russians", through education, intermarriage, etc. At least in the US people are living there willingly and had a choice in the matter.

It's like this everywhere. Do you think there just happened to be a people called "The English"? No, there were Gaelic peoples there, then Romans, then Angles and Saxons, then vikings, and on and on. Flows of people are the nature of history, both during wartime and peacetime. I'm as white as they come, but genetic tests show a tiny bit of African ancestry - from a percentage basis, maybe back into the 1600-1700s - because hey, there were "Moors" in Europe then too. "Most" genetics in Iceland sees Y chromosomes *mainly* showing Scandinavian roots and mitochondria *mainly* showing British isles roots, but there's also, for example, a not insignificant bit of Greenlandic genetics here.

Even the most isolated places in the world see a free flow of genetics. Tristan da Cunha is considered the most remote settlement on Earth, with its 238 people. Boats only arrive once every few months, and to visit you have to get special permission from the Island Council. There were 7 surnames on the island, from the island's original male settlers. This expanded to 10 in the 1960s after some islanders intermarried during an evacuation due to the island's volcano. But genetics show the presence of an Eastern European ancestor from the early 1900s, possibly from a Russian sailing ship. Even on the most remote place on Earth, genetic flow exists - and it does not harm a damned thing, and is in fact, very much a good thing.

And culture flows even easier than genetics. Culture is constantly changing, radically. Even the things that ultraconservatives see as timeless and want to force society back to aren't nearly as timeless as they think. Think, for example, of the idea of the "housewife", a woman who stays at home and raises the kids while the husband goes out to work. That's a Victorian invention that only became the "norm" for a few decades in the post-WWII period. Traditionally (after the hunter-gatherer phase, and the agrarian phase), the standard family unit was the family business. People work from home, and everyone - husband, wife, children - all work on different aspects of the business. Maybe the husband is a fisherman and the wife a fishmongerer. Maybe it's a family of cobblers, and the husband cuts the leather pieces while his wife stitches them. Etc. But everyone worked. In comes the Industrial Revolution. Now most everyone still works, but they're working out of the house. The home becomes a refuge, separate from the workplace. An increasing (though small) percentage of the population is starting to gain a comfortable income and gain airs of nobility. The notion of "separate spheres" arises, with the workplace being "the man's sphere" and the home being "the woman's sphere", and it became an aspirational goal to have a wife at home who doesn't have to work, a status symbol of wealth. Very few people actually lived like this - most people still needed to work. It wasn't until the post-WWII boom that this actually became any sort of "norm" in society, where it was the status for most adult women and those who had to work were looked down on for it. And it was a status that most women found they hated, which is what led to the later liberation movement.

Genetics shift. Culture shifts. And people are not their ancestors. Societies are fluid things, where genes flow and a marketplace of ideas works not based on ancestry, but what people enjoy. Focus on actually competing in the marketplace of ideas. If what you define as your "culture" is so great, convince people that it is. "Being a racist bigot" is, I hate to break it to you, not a good way to accomplish that. It's always the most cringeworthy inbred yokels out there drawling "The WHITE RACE is the SUPERIOR RACE!".

Still, Slashdot doesn't have to play along with their weasel wording. For example, "ergonomic collars that deliver an electric pulse" - just say "shock collar". Don't help them whitewash what they're talking about.

You're confusing the importance of avoiding Kessler syndrome in LEO with the difficulty of causing Kessler syndrome. GEO debris can potentially remain there for millions of years before interactions between the gravitational pull of the Sun, Earth, and Moon sufficiently perturb it. LEO debris remains for weeks to months. You have to have many orders of magnitude more debris in LEO to trigger Kessler Syndrome, where the rate of collisions exceeds the rate of debris loss.

The fact that a LEO Kessler Syndrome would also be short is something that exists on top of that.

It's also worth nothing that not only are modern satellites not only vastly better at properly disposing of themselves than they were in the 1970s when Kessler Syndrome was proposed, but they're also vastly better at avoiding debris strikes. All of these factors are multiplicative together.

Lol, I was thinking of this instead ;)

People forget that the primary concerns about Kessler Syndrome were about geosynchronous orbit, which used to be where all the most important satellites went (many of course still go there, but not the megaconstellations). It takes a long, long time for debris to leave GEO. But LEO is a very different beast.

They said it's internal rather than a collision, so probably a failed COPV would be my guess.

Yeah. In particular:

with fragments likely to fall to Earth over the next few weeks

LEO FTW. Kessler Syndrome is primarily a risk if you put too much stuff with too poor of an end-of-life disposal rate in GEO. End-of-life without proper disposal rates have declined exponentially since Kessler Syndrome was first proposed (manufacturers both understand the importance more, and do a better job, of decreasing the rate of failures before deorbit - in the past, sometimes there wasn't even attempts to dispose of a craft at end-of-life). And now we're increasingly putting stuff in LEO, where debris falls out of orbit relatively quickly. It's not impossible in LEO, esp. with higher LEO orbits - but it's much more difficult.

Or to put it another way: fragments can't build up to hit other things if they're gone after just a couple weeks.

And this trend is likely to continue - a lower percentage of premature failures, and decreasing altitudes / reentry times. Concerning ever-decreasing altitudes, we've already been doing this via use of ion engines to provide more reboost (with mission lifespans designed for only several years before running out of propellant, instead of decades like the giant GEO ones), but there's an increasing interest in "sky skimming" satellites that function in a way somewhat reminiscent of a ramjet - instead of krypton or xenon as the propellant for an ion engine, the sparse atmospheric air itself is the propellant, so the craft can in effect fly indefinitely until it fails, wherein it quite rapidly enters the denser atmosphere and burns up.

ED: "But it doesn't work for gravity with linear curvature"

Relativity = gravity is represented by the curvature of spacetime. Curvature is linear, R. The formula treats curvature linearly. As things get closer and curvature spikes, the math just scales at a 1:1 rate

Quadratic gravity = Squares the curvature. Doesn't really change things much when everything is far apart, but heavily changes things when everything is close together.

Pros: prevents infinities and other problems when trying to reconcile quantum theory with relativity ("makes the theory renormalizable"). E.g. you don't want to calculate "if I add up the probabilities of all of these possible routes to some specific event, what are the odds that it happens?" -> "Infinity percent odds". That's... a problem. Renormalization is a trick for electromagnetism that prevents this by letting the infinities cancel out. But it doesn't work with linear curvature - gravitons carry energy, which creates gravity, which carries more energy... it explodes, and renormalization attempts just create new infinities. But it does work with quadratic curvature - it weakens high-energy interactions and allows for convergence.

Cons: Creates "ghosts" (particles with negative energies or negative probabilities, which create their own problems). There's various proposed solutions, but none that's really a "eureka!" moment. Generally along the lines of "they exist but are purely virtual and don't interact", "they exist but they're so massive that they decay before they can interact with the universe", "they don't exist, we're just using the math out of bounds and need a different representation of the same", "If we don't stop at R^2 but also add in R^3, R^4, ... on to infinity, then they go away". Etc.

The theory isn't new, BTW. The idea is from 1918 (just a few years after Einstein's theory of General Relativity was published), and the work that led to the "Pros" above is from 1977.

A bit more about the latter. Beyond organophosphates, the main other alternative is pyrethroids. These are highly toxic to aquatic life, and they're contact poisons to pollinators just landing on the surface (some anti-insect clothing is soaked in pyrethrin for its effect). Also, neonicotinoids are often applied as seed coatings (which are taken up and spread through the plant), which primarily just affect the plant itself. Alternatives are commonly foliar sprays. This means drift to non-target impacts as well, such as in your shelterbelts, private gardens, neighbors' homes, etc. You also have to use far higher total pesticide quantities with foliar sprays instead of systematics, which not only drift, but also wash off, etc. Neonicotinoids can impact floral visitors, with adverse sublethal impacts but e.g. large pyrethroid sprayings can cause massive immediate fatal knockdown events of whole populations of pollinators.

Regrettable substitution is a real thing. We need to factor it in better. And that applies to nanoplastics as well.

So, when we say microplastics, we really mainly mean nanoplastics - the stuff made from, say, drinking hot liquids from low-melting-point plastic containers. And yeah, they very much look like a problem. The strongest evidence is for cardiovascular disease. The 2024 NEJM study for example found that for patients with above-threshold levels of nanoplastics in cartoid artery plaque were 4,5x more likely to suffer from a heart attack. Neurologically, they cross the brain-blood barrier (and quite quickly). A 2023 study found that they cause alpha-synuclein to misfold and clump together, a halmark of Parkinsons and various kinds of dementia. broadly, they're associated with oxidative stress, neuroinflammation, protein aggregation, and neurotransmitter alterations. Oxidative stress is due to cells struggling to break down nanoplastics in them. They're also associated with immunotoxicity, inflammatory bowel disease, and reproductive dysfunction, including elevating inflammatory markers, impairing sperm quality, and modulating the tumor microenvironment. With respect to reproduction, they're also associated with epigenetic dysregulation, which can lead to heritable changes.

And here's one of the things that get me - and let me briefly switch to a different topic before looping back. All over, there's a rush to ban polycarbonate due to concerns over a degradation product (bisphenol-A), because it's (very weakly) estrogenic. But typical effective estrogenic activity from typical levels of bisphenol-A are orders of magnitude lower than that of phytoestrogens in food and supplements; bisphenol-A is just too rare to exert much impact. Phytoestrogens have way better PR than bisphenol-A, and people spend money buying products specifically to consume more of them. Some arguments against bisphenol-A focus on what type of estrogenic activity it can promote (more proliferative activity), but that falls apart given that different phytoestrogens span the whole gamut of types of activation. Earlier research arguing for an association with estrogen-linked cancer seems to have fallen apart in more recent studies. It does seem associated with PCOS, but it's hard to describe it as a causal association, because PCOS is associated with all sorts of things, including diet (which could change the exposure rate vs. non-PCOS populations) and significant hormonal changes (which could change the clearance rate of bisphenol-A vs. non-PCOS populations). In short, bisphenol-A from polycarbonate is not without concern, but the concern level seems like it should be much lower than with nanoplastics.

Why bring this up? Because polycarbonate is a low-nanoplastic-emitting material. It is a quite resilient, heat tolerant plastic, and thus - being much further from its glass transition temperature - is not particularly prone to shedding nanoplastics. By contrast, its replacements - polyethylene, polypropylene, polyethylene terephthate, etc - are highly associated with nanoplastic release, particularly with hot liquids. So by banning polycarbonate, we increase our exposure to nanoplastics, which are much better associated with actual harms. And unlike bisphenol-A, which is rapidly eliminated from the body, nanoplastics persist. You can't get rid of them. If some big harm is discovered with bisphenol-A that suddenly makes the risk picture seem much bigger than with nanoplastics, we can then just stop using it, and any further harm is gone. But we can't do that with nanoplastics.

People seriously need to think more about substitution risks when banning products. The EU in particular is bad about not considering it. Like, banning neonicotinoids and causing their replacement by organophosphates, etc isn't exactly some giant win. Whether it's a benefit to pollinators at all is very much up in the air, while it's almost certain that the substitution is more harmful for mammals such as ourselves (neonicotinoids have very low mammalian toxicity, unlike e.g. organophosphates, which are closely related to nerve agents).

I hate all of this sales pressure BS - that the instant anyone hears your name you have to try to "convert" them to sales - and I literally run a webstore.

It's all so deeply anti-consumer, and I want no part in it.

Firstly, I see you have this notion that martian rocks must all be igneous.

You're not talking about rock, you're talking about regolith.

Depending on where the regolith is sourced

Regolith is not "sourced", it's blown across the whole planet. It's not simply "whatever the underlying strata is made out of".

But, since we are playing 'name the ignorance' in this exchange, your attestation stat perchlorate is 0.5% liberatable oxygen says 'Say i'm ignorant of basic chemistry without saying i'm ignorant of basic chemistry, and am bad at reading too.' The 0.5% statistic comes from the publication at bottom, and is the proportion of the regolith that is perchlorates.

I am the one who mentioned that regolith is 0.5% perchlorates, not that "perchlorates are 0.5% oxygen". *facepalm*

"Saying we'll get oxygen from the 0,5-1% of a poison in martian regolith, rather than bulk ice or CO2, is..."

For God's sake, learn to fucking read.

Washing the regolith to remove the perchlorate is a requirement for *any* other use of that regolith

Which is why you shouldn't be celebrating its existence. It is a problematic contaminant, not a resource.

As you have rightly pointed out, the water ice on mars is more 'frozen mud'. Cleaning the melt is going to be a necessary first step to using it *regardless*. That means either vacuum distillation, thermal distillation, or reverse osmosis filtration. Again, NOT OPTIONAL. This is necessary equipment that you need to bring, regardless.

And this just to get water, the most basic of offworld resources. And all of that equipment (especially the mining hardware itself) requires maintenance and spare parts, which impose more dependencies. And the TRL for use on Mars is low regardless.

You've gone from talking up the ease of operating on Mars to talking it down, yet your self-righteousness hasn't shifted at all in the process.

RO filtration is the least energy intensive of these.

Except, it isn't. 0,5-1% perchlorates. RO typically removes 90-95% of perchlorates. So you're down to ~500ppm. Human safety levels** are in the low parts per billion. You're five orders of magnitude off. Yes, you can purify water that far - and the more perchlorates, the easier - but you're talking an over millionfold reduction. It is not at all trivial. You're talking first RO to get it down to levels where it won't hinder bacterial growth, then bioreactor bacterial remediation, then filtration, then RO, then ion exchange. This is not some little, simple system.

** Plants can tolerate much more perchlorates than humans, but they also bioaccumulate perchlorates of exposed to them, so you have to reduce the water to low ppb levels.

The end products are clean water and perchlorate contaminated mud, and clean mud, with contaminated water.

Viola! *eyeroll*

And your "plan" for dealing with waste perchlorate doesn't just magically produce pure O2 and NaCl in the real world. First off, molten sodium perchlorate, which is what it becomes before it decomposes, is an extremely corrosive oxidizer. Exactly what are you planning to make the furnace out of, platinum? Secondly, you never get perfect decomposition. Apart from residual perchlorates, you have residual sodium chlorate, which is also corrosive, and is a literal herbicide. And your gas stream will contain contaminant chloride and chlorine dioxide, which, news flash, you don't want to breathe.

There is no way on Earth anyone would ever prefer this to just conducting electrolysis on the water that you've already purified.
