IMHO, LLMs will be an economic negative for years.

They'll do a worse job than humans,

but will still replace humans because they're cheaper for employers,

but really they're costlier, it's just that lots of costs get externalized to society by our horrible energy/tax policies.

Lose-lose-lose.
The Real AI Risk is ‘Meh’ Technology That Takes Jobs and Annoys Us All
While AI doomsday scenarios dwell on the risks posed by superintelligent robot overlords, one Nobel-Prize winning economist fears a more mundane possibility.

A succinct thread on the most important question of the day.

Can't decide if oaths and ceremony mean nothing anymore or if now more than ever, they mean everything.

Our world is particularly full of self serving scum that would destroy everything our ancestors have worked for in order to realize pathetic amounts of personal gain.

/ right before Jeopardy. I have no idea what the first 20 minutes is like, but the last 10 seems to be vacuous videos picked up from social media, with a 15 second update from the content creators. No AI needed to make that, but it’s every bit as mindless as any slop from Midjourney.

I consider that to be something like human-generated slop. There’s always been a supply/demand for that (pulp novels; Little Orphan Annie on the radio), but now it’s all swamping the potentially useful information.

My family doesn’t watch TV news, but sometimes we put on ABC News … /+

Are there physical reasons why folks’ brains are turning to mush? Perhaps? I’m not in a position to weigh in.

My hypothesis: incentives to soak in slop and offload cognitive tasks are making our brains sedentary. Add a firehose of empty data calories and you get “mental type II diabetes.”

What’s the cognitive equivalent of type II diabetes? That’s where we’re heading.

Over 40% of corn grown in Indiana is used to make ethanol that cars burn. One acre of corn yields about 16,500 vehicle-miles per year of ethanol, which sounds high until you realize that one acre of solar yields about 2,700,000 vehicle-miles per year: 16,000% more driving for a given plot of land.

That’s me! Before COVID, my daily commute had a lot of steps and stairs built in. Worked from home for more than 5 years and some weeks barely left the apartment. Retired in Aug. and making a point of going on walks whether I have an errand or not.

The U.S. system is decidedly inefficient. But our sedentary, car-oriented lifestyle has all sorts of knock-on adverse health effects that would likely keep spending higher-than-trend, and life expectancy lower-than-trend regardless.
jeffreywinters.bsky.social
Probably for the same reason: car dependency.

Solar & wind met 109% of new electricity demand, globally, in the first half of 2025.

Renewables are handling all new demand & are inexorably moving beyond, to chip away at the FF foundation.
Global Electricity Mid-Year Insights 2025 | Ember
Solar and wind outpaced demand growth in the first half of 2025, as renewables overtook coal’s share in the global electricity mix.

That’s been my theory since the summer of 2020.

Since COVID itself has enormous vascular and neurological effects, I’ve long wondered whether we’ve all become a little brain damaged from it, with the knock-on behavioral changes. Kinda the way a stroke or heart bypass surgery can leave a patient profoundly changed.

🚨NEW PAPER🚨
We all know the 2022 energy price shock fueled the cost of living crisis. It also caused a profit bonanza for the very rich. We show the US reaped the largest profits ($377bn) of any country. 50% went to the richest 1%, only 1% to the bottom 50%. A🧵 www.sciencedirect.com/science/arti...
River or sankey diagram showing the allocation of profits from global oil and gas companies to quantiles of the US wealth size distribution via financial system intermediaries, such as asset managers, and categories of ultimate beneficiaries, such as business owners, pension funds and shareholders in listed companies. The scale is hundreds of billions of US dollars, and ultimately 50.4% of profits reaching the US personal wealth distribution go to the richest 1% of households.

Does the news reflect what we die from?
The image presents a comparison of the leading causes of death in the United States for 2023 and the media coverage these causes receive from three news outlets: The New York Times, The Washington Post, and Fox News. 

In the footer, it notes the data sources, indicating that the information is based on media mentions from Media Cloud (2025) and death data from the US CDC (2025) and the Global Terrorism Index, with a clarification that values are normalized to sum to 100%.

9/ The global cost implications are profound. A storage-heavy, curtailment-optimised approach increases system costs by an average of 103.1%. In stark contrast, an overcapacity-focused, cost-optimised approach increases costs by only 3.3%.

I once read a chef's comment that "most people don't understand that American cheese is supposed to be a cheese *sauce*, and just happens to be solid at room temperature."

Incredibly proud of my old crew at @asmedotorg.bsky.social @mengineeringmag.bsky.social for nabbing two Eddies last night. Best little magazine no one’s ever heard of. Onward and upward.
Sarah Alburakeh and Louise Poirier with the trophies for best single issue and best body of work.
