Saw a tweet that said something around:

"cannot emphasize enough how horrid chatgpt is, y'all. it's depleting our global power & water supply, stopping us from thinking or writing critically, plagiarizing human artists. today's students are worried they won't have jobs because of AI tools. this isn't a world we deserve"

I've seen some of your AI posts and they seem nuanced, but how would you respond do this? Cause it seems fairly-on point and like the crux of most worries. Sorry if this is a troublesome ask, just trying to learn so any input would be appreciated.

i would simply respond that almost none of that is true.

'depleting the global power and water supply'

something i've seen making the roudns on tumblr is that chatgpt queries use 3 watt-hours per query. wow, that sounds like a lot, especially with all the articles emphasizing that this is ten times as much as google search. let's check some other very common power uses:

running a microwave for ten minutes is 133 watt-hours

gaming on your ps5 for an hour is 200 watt-hours

watching an hour of netflix is 800 watt-hours

and those are just domestic consumer electricty uses!

a single streetlight's typical operation 1.2 kilowatt-hours a day (or 1200 watt-hours)

a digital billboard being on for an hour is 4.7 kilowatt-hours (or 4700 watt-hours)

i think i've proved my point, so let's move on to the bigger picture: there are estimates that AI is going to cause datacenters to double or even triple in power consumption in the next year or two! damn that sounds scary. hey, how significant as a percentage of global power consumption are datecenters?

1-1.5%.

ah. well. nevertheless!

what about that water? yeah, datacenters use a lot of water for cooling. 1.7 billion gallons (microsoft's usage figure for 2021) is a lot of water! of course, when you look at those huge and scary numbers, there's some important context missing. it's not like that water is shipped to venus: some of it is evaporated and the rest is generally recycled in cooling towers. also, not all of the water used is potable--some datacenters cool themselves with filtered wastewater.

most importantly, this number is for all data centers. there's no good way to separate the 'AI' out for that, except to make educated guesses based on power consumption and percentage changes. that water figure isn't all attributable to AI, plenty of it is necessary to simply run regular web servers.

but sure, just taking that number in isolation, i think we can all broadly agree that it's bad that, for example, people are being asked to reduce their household water usage while google waltzes in and takes billions of gallons from those same public reservoirs.

but again, let's put this in perspective: in 2017, coca cola used 289 billion liters of water--that's 7 billion gallons! bayer (formerly monsanto) in 2018 used 124 million cubic meters--that's 32 billion gallons!

so, like. yeah, AI uses electricity, and water, to do a bunch of stuff that is basically silly and frivolous, and that is broadly speaking, as someone who likes living on a planet that is less than 30% on fire, bad. but if you look at the overall numbers involved it is a miniscule drop in the ocean! it is a functional irrelevance! it is not in any way 'depleting' anything!

'stopping us from thinking or writing critically'

this is the same old reactionary canard we hear over and over again in different forms. when was this mythic golden age when everyone was thinking and writing critically? surely we have all heard these same complaints about tiktok, about phones, about the internet itself? if we had been around a few hundred years earlier, we could have heard that "The free access which many young people have to romances, novels, and plays has poisoned the mind and corrupted the morals of many a promising youth."

it is a reactionary narrative of societal degeneration with no basis in anything. yes, it is very funny that laywers have lost the bar for trusting chatgpt to cite cases for them. but if you think that chatgpt somehow prevented them from thinking critically about its output, you're accusing the tail of wagging the dog.

nobody who says shit like "oh wow chatgpt can write every novel and movie now. yiou can just ask chatgpt to give you opinions and ideas and then use them its so great" was, like, sitting in the symposium debating the nature of the sublime before chatgpt released. there is no 'decay', there is no 'decline'. you should be suspicious of those narratives wherever you see them, especially if you are inclined to agree!

plagiarizing human artists

nah. i've been over this ad infinitum--nothing 'AI art' does could be considered plagiarism without a definition so preposterously expansive that it would curtail huge swathes of human creative expression.

AI art models do not contain or reproduce any images. the result of them being trained on images is a very very complex statistical model that contains a lot of large-scale statistical data about all those images put together (and no data about any of those individual images).

to draw a very tortured comparison, imagine you had a great idea for how to make the next Great American Painting. you loaded up a big file of every norman rockwell painting, and you made a gigantic excel spreadsheet. in this spreadsheet you noticed how regularly elements recurred: in each cell you would have something like "naturalistic lighting" or "sexually unawakened farmers" and the % of times it appears in his paintings. from this, you then drew links between these cells--what % of paintings containing sexually unawakened farmers also contained naturalistic lighting? what % also contained a white guy?

then, if you told someone else with moderately competent skill at painting to use your excel spreadsheet to generate a Great American Painting, you would likely end up with something that is recognizably similar to a Norman Rockwell painting: but any charge of 'plagiarism' would be absolutely fucking absurd!

this is a gross oversimplification, of course, but it is much closer to how AI art works than the 'collage machine' description most people who are all het up about plagiarism talk about--and if it were a collage machine, it would still not be plagiarising because collages aren't plagiarism.

(for a better and smarter explanation of the process from soneone who actually understands it check out this great twitter thread by @reachartwork)

today's students are worried they won't have jobs because of AI tools

i mean, this is true! AI tools are definitely going to destroy livelihoods. they will increase productivty for skilled writers and artists who learn to use them, which will immiserate those jobs--they will outright replace a lot of artists and writers for whom quality is not actually important to the work they do (this has already essentially happened to the SEO slop website industry and is in the process of happening to stock images).

jobs in, for example, product support are being cut for chatgpt. and that sucks for everyone involved. but this isn't some unique evil of chatgpt or machine learning, this is just the effect that technological innovation has on industries under capitalism!

there are plenty of innovations that wiped out other job sectors overnight. the camera was disastrous for portrait artists. the spinning jenny was famously disastrous for the hand-textile workers from which the luddites drew their ranks. retail work was hit hard by self-checkout machines. this is the shape of every single innovation that can increase productivity, as marx explains in wage labour and capital:

“The greater division of labour enables one labourer to accomplish the work of five, 10, or 20 labourers; it therefore increases competition among the labourers fivefold, tenfold, or twentyfold. The labourers compete not only by selling themselves one cheaper than the other, but also by one doing the work of five, 10, or 20; and they are forced to compete in this manner by the division of labour, which is introduced and steadily improved by capital. Furthermore, to the same degree in which the division of labour increases, is the labour simplified. The special skill of the labourer becomes worthless. He becomes transformed into a simple monotonous force of production, with neither physical nor mental elasticity. His work becomes accessible to all; therefore competitors press upon him from all sides. Moreover, it must be remembered that the more simple, the more easily learned the work is, so much the less is its cost to production, the expense of its acquisition, and so much the lower must the wages sink – for, like the price of any other commodity, they are determined by the cost of production. Therefore, in the same manner in which labour becomes more unsatisfactory, more repulsive, do competition increase and wages decrease”

this is the process by which every technological advancement is used to increase the domination of the owning class over the working class. not due to some inherent flaw or malice of the technology itself, but due to the material realtions of production.

so again the overarching point is that none of this is uniquely symptomatic of AI art or whatever ever most recent technological innovation. it is symptomatic of capitalism. we remember the luddites primarily for failing and not accomplishing anything of meaning.

if you think it's bad that this new technology is being used with no consideration for the planet, for social good, for the flourishing of human beings, then i agree with you! but then your problem shouldn't be with the technology--it should be with the economic system under which its use is controlled and dictated by the bourgeoisie.

The Best News of Last Week

1. ‘It was an accident’: the scientists who have turned humid air into renewable power

Greetings, readers! Welcome to our weekly dose of positivity and good vibes. In this edition, I've gathered a collection of uplifting stories that will surely bring a smile to your face. From scientific breakthroughs to environmental initiatives and heartwarming achievements, I've got it all covered.

In May, a team at the University of Massachusetts Amherst published a paper declaring they had successfully generated a small but continuous electric current from humidity in the air. They’ve come a long way since then. The result is a thin grey disc measuring 4cm across.

One of these devices can generate a relatively modest 1.5 volts and 10 milliamps. However, 20,000 of them stacked, could generate 10 kilowatt hours of energy a day – roughly the consumption of an average UK household. Even more impressive: they plan to have a prototype ready for demonstration in 2024.

2. Empty Office Buildings Are Being Turned Into Vertical Farms

Empty office buildings are being repurposed into vertical farms, such as Area 2 Farms in Arlington, Virginia. With the decline in office usage due to the Covid-19 pandemic, municipalities are seeking ways to fill vacant spaces.

Vertical farming systems like Silo and AgriPlay's modular growth systems offer efficient and adaptable solutions for converting office buildings into agricultural spaces. These initiatives not only address food insecurity but also provide economic opportunities, green jobs, and fresh produce to local communities, transforming urban centers in the process.

3. Biden-Harris Administration to Provide 804,000 Borrowers with $39 Billion in Automatic Loan Forgiveness as a Result of Fixes to Income Driven Repayment Plans

The Department of Education in the United States has announced that over 804,000 borrowers will have $39 billion in Federal student loans automatically discharged. This is part of the Biden-Harris Administration's efforts to fix historical failures in the administration of the student loan program and ensure accurate counting of monthly payments towards loan forgiveness.

The Department aims to correct the system and provide borrowers with the forgiveness they deserve, leveling the playing field in higher education. This announcement adds to the Administration's efforts, which have already approved over $116.6 billion in student loan forgiveness for more than 3.4 million borrowers.

4. F.D.A. Approves First U.S. Over-the-Counter Birth Control Pill

The move could significantly expand access to contraception. The pill is expected to be available in early 2024.

The Food and Drug Administration on Thursday approved a birth control pill to be sold without a prescription for the first time in the United States, a milestone that could significantly expand access to contraception. The medication, called Opill, will become the most effective birth control method available over the counter

5. AIDS can be ended by 2030 with investments in prevention and treatment, UN says

It is possible to end AIDS by 2030 if countries demonstrate the political will to invest in prevention and treatment and adopt non-discriminatory laws, the United Nations said on Thursday.

In 2022, an estimated 39 million people around the world were living with HIV, according to UNAIDS, the United Nations AIDS program. HIV can progress to AIDS if left untreated.

6. Conjoined twins released from Texas Children’s Hospital after successfully separated in complex surgery

Conjoined twins are finally going home after the pair was safely separated during a complex surgery at Texas Children’s Hospital in June.

Ella Grace and Eliza Faith Fuller were in the neonatal intensive care unit (NICU) for over four months after their birth on March 1. A large team of healthcare workers took six hours to complete the surgery on June 14. Seven surgeons, four anesthesiologists, four surgical nurses and two surgical technicians assisted with the procedure.

7. From villains to valued: Canadians show overwhelming support for wolves

Despite their record in popular culture, according to a recent survey, seven in 10 Canadians say they have a “very positive” view of the iconic predators.

Here's a fascinating video about how wolves changed Yellowstone nat'l park:

"Passed in February [2024], a massive subsidy program to help Indian households install rooftop solar panels in their homes and apartments aims to provide 30 gigawatt hours of solar power to the nation’s inventory.

The scheme, called PM-Surya Ghar, will provide free electricity to 10 million homes according to estimates, and the designing of a national portal—a sort of Healthcare.gov for solar panels—will streamline the process of installation and payment.

The program was cooked up because India had fallen woefully behind on its planned installations for rooftop solar. In many parts of the subcontinent, the sun is absolutely brutal and relentless, but by 2022, Indian rooftop solar power generation topped out at 11 gigawatts, which was 29 gigawatts under a national target set a decade ago.

Part of the challenge, Euronews reports, is that approval from various agencies and departments—as many as 21 different signatures in some cases—was needed to place a solar array on your house. Aside from this bureaucratic nightmare, the cost of installation was often higher than $5,000; more than half the average yearly income for a working Indian urbanite.

Under PM-Surya Ghar, subsidies for a 2-kilowatt solar array will cover as much as 60% of the installation costs, falling to 40% for arrays 3 kilowatts or higher. Loans set at around 7% interest rates will help families in need get started. 750 billion Indian rupees, or $9 billion has been set aside for the project.

Even in New Delhi, which can be covered in clouds and smog for days, solar users report saving hundreds during summer time on their electricity costs, with one apartment shaving $700 every month off energy bills.

PM-Surya Ghar is also seen as having the potential to cause a boom in the Indian solar market. Companies no longer have to go running around for planning and permitting requirements, and the government subsidies ensure their customer base can grow beyond the limits of household income."

AI Reminder

Quick reminder folks since there's been a recent surge of AI fanfic shite. Here is some info from Earth.org on the environmental effects of ChatGPT and it's fellow AI language models.

"ChatGPT, OpenAI's chatbot, consumes more than half a million kilowatt-hours of electricity each day, which is about 17,000 times more than the average US household. This is enough to power about 200 million requests, or nearly 180,000 US households. A single ChatGPT query uses about 2.9 watt-hours, which is almost 10 times more than a Google search, which uses about 0.3 watt-hours.

According to estimates, ChatGPT emits 8.4 tons of carbon dioxide per year, more than twice the amount that is emitted by an individual, which is 4 tons per year. Of course, the type of power source used to run these data centres affects the amount of emissions produced – with coal or natural gas-fired plants resulting in much higher emissions compared to solar, wind, or hydroelectric power – making exact figures difficult to provide.

A recent study by researchers at the University of California, Riverside, revealed the significant water footprint of AI models like ChatGPT-3 and 4. The study reports that Microsoft used approximately 700,000 litres of freshwater during GPT-3’s training in its data centres – that’s equivalent to the amount of water needed to produce 370 BMW cars or 320 Tesla vehicles."

Now I don't want to sit here and say that AI is the worst thing that has ever happened. It can be an important tool in advancing effectiveness in technology! However, there are quite a few drawbacks as we have not figured out yet how to mitigate these issues, especially on the environment, if not used wisely. Likewise, AI is not meant to do the work for you, it's meant to assist. For example, having it spell check your work? Sure, why not! Having it write your work and fics for you? You are stealing from others that worked hard to produce beautiful work.

Thank you for coming to my Cyn Talk. I love you all!

The world’s largest solar panel image, a horse, was constructed in the Kubuqi Desert of Inner Mongolia, China starting in 2017. This massive pattern was built with 196,320 solar panels and covers nearly 1.4 square kilometers (0.54 square miles). It is part of a larger photovoltaic generation base with an annual output of 4 billion kilowatt hours.

Two 650-foot-tall (200-m) towers have risen in China's Gansu Province. Combined with an array of 30,000 mirrors arranged in concentric circles, the new facility is expected to generate over 1.8 billion kilowatt-hours of electricity every year.

While photovoltaic panels that directly convert sunlight to electricity are what most people think of when they hear the term "solar power," there is another method of harvesting the Sun's power that's been steadily developing since the early 1980s. Known as solar thermal or concentrated solar power (CSP), these systems rely on mirrors known as heliostats to bounce sunlight to a central gathering point. There, the concentrated beams heat a transfer fluid that in turn heats a working fluid. This fluid then evaporates, turns a turbine, and generates electricity.

In 2014, what was then the world's largest solar thermal power station opened in the Mojave Desert in the United States. [The] facility consists of three different towers surrounded by heliostat arrays and has a capacity of 392 megawatts. [...] The world's largest CSP, the Noor Complex Solar Power Plant, now operates in the Sahara Desert in Morocco where it churns out 510 megawatts of power.[...]

Much like the facility in the US, the Ghazhou solar thermal energy storage project will use multiple towers: in this case, two of them, both sharing the same steam turbine.

But unlike the US facility, where each tower is surrounded by its own field of heliostats, the Chinese project will deploy a field of mirrors set in overlapping concentric circles. The mirrors will then be able to follow the path of the Sun and reflect light to either tower in the most efficient way possible. It's an advance that will improve CSP efficiency significantly, says project manager, Wen Jianghong.

"The mirrors in the overlapping area can be utilized by either tower," he said. "This configuration is expected to enhance efficiency by 24 percent." Helping that efficiency along is the fact that the mirrors being used have a 94% reflection efficiency, meaning that most of the solar energy that hits them is beamed back to the power-producing towers.

compiling information about the kineema, because I'm normal

hi. you may remember me from this post talking about how the kineema doesn't have a hood. I've decided to compile all the *other* info I can get on the kineema and comment on it. hopefully this is okay to read

---

let's start with what I could find on fayde

INTERFACING - With its air-cooled, rear-mounted twelve cylinder compression ignition engine driving the rear wheels through a four-speed manual gearbox, the Kineema is able to reach 100 kilometres per hour in 13.5 seconds. And go on to a top speed of 180 kilometres an hour. YOU - Won't it roll over in the first sharp corner? INTERFACING - The high centre of balance is offset by a large battery bank mounted at the bottom of the cabin, feeding all the auxiliary systems and making the Kineema effectively a mobile power plant.

air-cooled: no radiator. I assume this is what those big heat-sink looking things on sides of the engine are for

compression ignition engine: diesel, no spark plugs (diesel engines are named after a guy, rudolph diesel, so I guess in elysium they didn't do that)

rear wheel drive: this is pretty obvious just looking at the thing

100 kilometres per hour in 13.5 seconds: not very fast acceleration compared to modern cars, but the history of cars in elysium is obviously very different to irl

battery bank: this is the only thing keeping the kineema from tipping backwards onto its ass as soon as you accelerate

YOU - "What's it packing there?" (Point to the engine.) KIM KITSURAGI - "Hundred-and-thirty." INTERFACING - I reckon that's a seven-litre V12 there. ENCYCLOPEDIA - Man, that's got to be a major advancement over the KR18GU engine on the old Coupris 40. YOU - "Wait, hundred-and-thirty what?" KIM KITSURAGI - "Kilowatts," the lieutenant replies laconically.

130 kilowatts: ~174 horsepower

YOU - "That's what..." (Rub your chin.) "... a seven-litre V12?" KIM KITSURAGI - "Seven-point-two. Supercharged." The lieutenant is trying to suppress a smug smile. Unsuccessfully. EMPATHY - Saying these words brings him immense joy.

7.2 litre engine: space inside the cylinders. 7.2L/12 = 600cc per cylinder

supercharged: has a supercharger. forces more air into the engine, powered by the crankshaft (as opposed to turbochargers which are powered by the exhaust)

YOU - Run your fingers over one of the steering levers. COUPRIS KINEEMA - The white suede feels luxurious under the touch and the metal clutch handle so very familiar in your palm... INTERFACING - Your fingers waste no time closing around the handle. Clutch disengaged. Release the handle -- clutch drops -- right foot yearns for the familiar touch of the accelerator pedal. You have synced with the machine's mechanical circulation.

YOU - "A *driver* would wear down their right shoe before the left -- the accelerator is on the right. And remember that abandoned lorry cabin we found?"

steering levers: instead of a steering wheel. not exactly sure how they'd work. I *really* don't want it to have differential steering like a zero-turn mower looking at this video of kim driving it looks like the front wheels are the ones steering

clutch handle: instead of a pedal, the clutch is a handle on one of the levers. seems that accelerator and (probably) brake are still pedals

accelerator is on the right: does everyone left-foot brake??? I guess if the clutch handle is standard then that would make sense

ABANDONED LORRY - The glass on the side windows is tinted and covered with dust. You can barely make out the shape of a seat and two steering levers. [...] YOU - Check the pedals. ABANDONED LORRY - You wedge yourself under the steering-wheel to get a better look. Seems like the few tools lying around here -- a hammer, a pair of pliers, a rusty wrench -- have been casually thrown there by the disorganized driver. ABANDONED LORRY - But one odd detail does catch your eye: A piece of sandpaper has been glued to the throttle.

STEERING WHEEL TYPO

---

alright, let's actually take a look at this thing

two door: the kineema has a single driver's seat and two seats in the back. looks like you'd need to move the front seat forward to let anyone else in

suspension: the back wheels look like they have some sort of spring (the axle is connected to it, so how are the wheels being driven??? same with the coupris 40). I assume the front arms also act as a spring

rear view mirror: looks like there's no rear view mirror, since you wouldn't see shit

aerodynamics: bad

seat belts:

¯\_(ツ)_/¯

going out with nct dream!

warnings: mentions of alcohol and drug use (weed), slightly suggestive

if you’re going to engage in the use of intoxicating substances please make sure to do it in a safe and responsible manner. take care of yourselves and always look out for your friends and partners.

mark

not huge on loud music and packed spaces, so he rarely goes clubbing. however, when he gets down he gets down. hands on your hips when you dance together. does not let you out of his sight. orders a FEAST’S worth of food delivery ahead, especially if you’ve been drinking. guides you out by the shoulders while holding your belongings. makes sure to get a video of you drunkenly confessing your undying love for him (he sounds equally drunk in the background).

renjun

sends you like 10 different pics for you to choose his outfit. big late night dinner before the function at your go-to pregame meal place. knows every song ever made and sings at the TOP of his lungs with you. does not stop smiling once, it’s so contagious. is in his own lil world with you. has to step outside for some cool fresh air every hour. eventually y’all get to kissing and decide that no night out dancing could be more fun than a drunk night home ( :) ) so you leave early.

jeno

makes you do a spin for him to see your full outfit. keeps getting close to your ear and telling you how good you look. matches your energy perfectly. like if you feel like grinding and getting all sticky and sweaty until the sun rises, he’s in. you usually tap out before 3am though. if you’re not too drunk you share a joint while you debrief the events of the night. rummages through your fridge for a snack before coming to bed. (repeats how hot you looked one more time).

haechan

y’all usually opt for staying in and getting wine drunk in the bath together, but when you do go out… it’s balls to the wall! tequila shots left and right. probably bar/club hopping. you guys dance like you’re never seeing each other again after the night ends. full on makes out with you on the dance floor. y’all leave when the world starts spinning a bit too much, giggling while getting into your taxi. whoever wakes up first makes the hangover meal.

jaemin

not a big drinker, but always assures you that you can have fun however you want to and he’ll be there to take care of you. has a billion kilowatt smile on while watching you dance. cups the side of your neck and pulls you in CLOSE whenever you try telling him something. does this bit where he sidles up next to you and asks if he can get you a drink. hands you a water bottle every once in a while. makes sure you do your skincare before you knock out at home.

chenle

makes rounds saying hi to people, introducing you to everyone you don’t already know. keeps nuzzling your neck because your going-out fragrance is his favorite. doesn’t let go of your hand once. takes his alcohol on the rocks to look cool, but sips from your mixed drink as a chaser. your nr 1 hypeman. kisses your cheek when someone points a camera at you (the picture turns out cute as fuck). come-hither motions at you while singing sexy back by jt.

jisung

literally only goes to these things for you. is somehow still shocked that he has fun even after the nth time. dances his ass off fr. pulls your hips back into his by your belt loops. sporadically kisses your jaw and the side of your neck. he doesn’t like staying out too late. holds your hand in both of his all the way home. as much as he loves dancing with you, his favorite part of the night is when you people watch on his balcony as you pass a joint back and forth.
