I am reading Daniel Levintins excellent book ”The Organized Mind” and this part perfectly explains why I sometimes get stuck in multi-hour obsessive TypeScript rabbit holes to create the perfectly (unnecessary) typed expression for a problem.

Me in the WSJ today, arguing that the relationship between social media and mental health is not clear cut, and bans for teenagers aren't the answer. (NB I did not pick this title, I would have gone for something kinder. I understand why people are worried.) 1/ www.wsj.com/health/welln...

How many % of the currently experienced value of large language models come from the fact that they ingest in a way that a traditional search engines would have been sued and blocked to oblivion if they did? And how expensive would they be if they paid fairly for the privilege?

Every major UK newspaper - left, right, broadsheet, tabloid - is running a front page campaign against copyright carveouts for AI training. I can't remember the last time any political cause had such broad support, let alone one so anti-big tech and so economically consequential.

New article by me! It's a common mistake to think the TFR is a prediction of the average number of children women will have over their lifetimes. But it's not. The TFR can decline even when the eventual number of children per woman stays constant or even increases; the opposite can happen too. 🧵

A line graph compares two measures of fertility rates in Sweden over time: the total fertility rate and the completed cohort fertility rate.

The total fertility rate is depicted using a red line, which shows a downward trend starting around the early 1900s, with fluctuations and a gradual decline to about 1.5 in 2022. 

The completed cohort fertility rate is illustrated with a blue line, with the time axis showing the women's birth year. It shows an initial decline followed by a stable fertility rate.

A note at the bottom states that the completed cohort fertility rate has been shifted by 30 years to align with the respective birth years of women. The data source is the Human Fertility Database (2024) and the chart is published by Our World in Data.
