Nuclear reactors use most surface water, not ground water.

Datacentres are no pickier. You can even cool a datacentre with saltwater, you just need a heat exchanger.

Also, closed loop does not evaporate. The loop is not closed if stuff escapes from it.

You're arguing with the actual terminology used in the nuclear industry. "Closed loop" or "closed cycle" designs have the water pumped in a cycle through cooling towers. The towers lose water to evaporation, taking heat with them, but the rest of the water is returned to be reheated again. "Open loop" or "open cycle" designs have no cooling towers. The water is heated and just discharged hot. They consume much more water (over an order of magnitude more), but most of that is returned. Closed loop are more common, but you see open loop in some older designs, and in seawater-cooled reactors.

"How often do you think I print?"

Seemingly not very.

I've printed many hundreds of kg on my P1S, thanks.

I do not consider having to write data out to a card and transport it back and forth between the printer and the computer to be the pinnacle of convenience. That's something that would be considered embarrassingly inconvenient for a 1980s printer, let alone a modern net-connected device. And it's designed to be inconvenient for non-cloud prints for a reason.

Amazon I.T. .... your ridiculous middle management and their obsession over metrics make stories like these pathetic, yet not unexpected at all.

I.T. is going down a spiral where management treats you like a "digital janitor". I'm old enough to remember this being a fairly respected career path. People in most offices had a combination of fear and awe of the "I.T. guys" because ultimately, there was a realization the entire business relied on the technology to survive. If the server or network went down, everything ground to a halt. You simply didn't treat the team poorly who held the keys to the kingdom.

It's a very different atmosphere today. Now, everyone's worried about how to cut costs and achieve the maximum return. I.T. may be critically important to a business's success, but nobody cares. There's the constant suggestion that AI is about to replace half of them anyway, and the trick is to wring every bit of productivity out of the existing staff until they quit. Then you just replace them and repeat.

If you're reading this and thinking, "It's not like that at all where I work!", congratulations! You're part of a diminishing bit of sanity out there. The last place I worked like that, though? The owner passed away and the company was sold, and it's no longer an exception to the rule.

The idea someone needs to micro manage their "knowledge workers" to the extent they keep tabs on how many feet their mouse has rolled each day? Well, that's plain insulting they'd even think it's sensible!

While universal basic income is a useful policy tool and I think we WILL reach it eventually, there are economics papers out there that demonstrate that, sans Pigouvian transaction tax, AI is a race to the bottom.

The AI Layoff Trap by Brett Hemenway Falk and Gerry Tsoukalas is still sitting on my desktop. A quick Google search reveals they are not the only ones who are pursuing this line of thinking.

BUt here in the U.S. "muh freedumb" will ensure that we run that race till the bottom falls out. Hopefully Asia and Europe play this transition a bit smarter, so something of our society continues.

Also, anything sounds big when you put it in gallons. Doesn't sound so big when you mention that's 92 acre feet, the amount used by less than 20 acres / 8 hectares of alfalfa per year. Or when you mention that a typical *closed loop* 1GW nuclear reactor uses 6-20 billion gallons of cooling water per year (once-through uses 200-500 billion gallons, though most of that is returned, whereas closed loop evaporates it)

They never really talk about any of them except for the educational discount, to my knowledge? But for as long as I can remember, Apple also offered military discounts:

They also run government employee discounts, typically by way of special online stores you have to shop in. For example, Washington DC government workers can go here: https://dchr.dc.gov/page/apple...

I don't think it has anything to do with that. As soon as I saw the headline, my mind went "cohort study". And sure enough, yeah, it's a cohort study. Remember that big thing about how wine improves your health, and then it turned out to just be that people who drink wine tend to be wealthier and thus have better health outcomes? And also, the "sick quitter" effect, where people who are in worse health would tend to stop drinking, so you ended up with extra sick people in the non-wine group? Same sort of thing. This study says they're controlling for a wide range of factors, but I'd put money on it just being the same sort of spurious correlations.

I'd agree, except it really depends what you want to do in life. Where AI really does more damage than good is in the Fine Arts. So far, AI has "empowered" the stealing of original creative work by cartoonists, painters and paid photographers, to regurgitate it into "mash-ups" it pretends it came up with organically in response to requests to "draw me a ". It's, similarly, encouraged producing musical jingles and pieces that devalue real, human musicians as part of the process. (If you're a small business looking for a catchy jingle or theme to put in all your radio commercials today? Chances are you opt to save a little money by AI generating something up via a service like Suno, instead of hiring a professional musicians who writes them. That results in AI "synth singers" that all start to sound alike as you hear enough of the content, and to at least some extent? Music that sounds generic and canned, too, due to a limited number of drum riffs and fills, guitar licks and other details the AI uses repeatedly when instructed to play in specific genres.

Even if you believe this is just part of the transition of AI into something far better than it is today? You're just cheering on a world where it will become a special treat to pay premiums for a "real, human-crafted work", while the masses only consume AI art. That doesn't bode well for society in the future, if you ask me.

Jensen Huang to college grads: "Run. Don't walk" toward AI

https://www.axios.com/2026/05/...

Nvidia founder and CEO Jensen Huang told graduates at Carnegie Mellon University in Pittsburgh yesterday that demand for AI infrastructure is creating a "once-in-a-generation opportunity to reindustrialize America and restore the nation's capacity to build."

Why it matters: With many college grads fearing AI could obliterate their career dreams, Huang pointed to boundless opportunity as a "new industry is being born. A new era of science and discovery is beginning ... I cannot imagine a more exciting time to begin your life's work."

Nvidia, which makes AI chips, is the world's most valuable company. Huang told 5,800 recipients of undergraduate and graduate degrees that the AI buildout will require plumbers, electricians, ironworkers, and builders for chip factories, data centers and advanced manufacturing facilities.

"No generation has entered the world with more powerful tools â" or greater opportunities â" than you," he said. "We are all standing at the same starting line. This is your moment to help shape what comes next. So run. Don't walk."

"Every major technological revolution in history created fear alongside opportunity," Huang added. "When society engages technology openly, responsibly, and optimistically, we expand human potential far more than we diminish it."

"I just put my models on a usb drive then plug said drive into the printer."

You must have a lot of spare time on your hands.

"It works great locally" - Um, no it doesn't?

They've made a nice easy-to-use ecosystem. For $400 you can get a P1S that supports adding an AMS, auto bed leveling, enclosed-chamber printing, high precision, high print speeds, and 300/100C nozzle/plate temps, and has an easy cloud print service and a robust ecosystem of models you can just download and print with no extra config straight from the app.

But yeah, their behavior is increasingly entering bad-actor territory. I wonder how long it'll be before they lock entry-level printers into their branded filament?

The market IS white hot right now, but the Hormuz hit is just starting to land. Demand at the edges is what sets the price - if all southeast Asian gamers are spending the GPU money on gas, that cools the rush. And I have no confidence any of these datacenter announcements are going to lead to actual builds. Companies talked a great game, but the political heat is on, the electric and water constraints are real, and advances like TurboQuant, which conservatively speaking offers a 4x boost to existing GPUs ... now layer the U.S. economic hit from Hormuz, which will only be a little bit behind the Asian blowout.

The AI/datacenter/GPU self dealing circle looks more like the derivative traders of 2008 with each passing day. Just like CDOs, that "money" is all conditional, and when conditions change, it's all gone. Society got some nice frontier models and advances in manufacturing out of it, now if corporate America takes even half a step back on the rush ... the market won't just vanish, because there IS a lot of benefit to using LLMs, but the demand may only match what's already been built. We'll take the hit from it, then the economy will rebound from a bunch of startups pillaging the existing firms that are politically incapable of making the needed culture change.
