Why do we have so many meetings? Few workplace features are so scorned, yet seemingly so necessary. This paper provides the first large-scale economic evidence on workplace meetings using an original survey of more than 9,000 workers linked to matched employer–employee administrative data from Norway. We show that meetings are both common and costly, consuming an average of 12 percent of work hours and 14 percent of firm wage bills. Planning, problem solving, information sharing, and project coordination account for the majority of meeting activity. High-paying and high-revenue firms devote more resources to meetings despite facing a substantially higher opportunity cost of employee time. Meeting frequency and intensity are positively related to worker wage growth. Workers in meeting-intensive firms report greater on-the-job learning, and interactions with more senior colleagues are associated with stronger wage growth, suggesting that knowledge transmission within firms is an important mechanism. Meetings are the broccoli of work – widely disliked, but probably good for us anyway.
If there is any movement to pause AI development, it will come from the general public's dislike of these companies. Not from the AI safety angle.
This sentence is accurate, but inevitably leads to the confusion you see in these comments.
1. There are strong economies of scale in hosting inference (batched prompts, high uptime, shared infrastructure).
2. There are physical limits on how much memory we will be able to produce over the next few years. Demand will probably scale at least as fast as production does, so we won't be saved by falling prices.
What there isn't is good evidence that these full body scans actually improve outcomes.

"Reduce," "Lower" - this is all causal language for a study that is purely observational. The authors do a good job keeping causal language out of the paper, so why can't media do the same?
This leads to an environment where everyone knows that "correlation != causation," but almost nobody understands why.
Observational studies like these are useful for guiding future research, but, on their own, they're essentially useless for informing lifestyle changes.
However, the estimates are still probably overestimated. Confounding, p-hacking, publication bias, all move us towards larger estimates.
I wonder if there will be another round of simplifications as models continue to improve, or if the scaffolding is here to stay.
