Wrote a short piece arguing that higher ed must help steer AI. TLDR: If we outsource this to tech, we outsource our whole business. But rejectionism is basically stalling. If we want to survive, schools themselves must proactively shape AI for education & research. [1/6, unpaywalled at 5/6] +

Opinion | AI Is the Future. Higher Ed Should Shape It.

If we want to stay at the forefront of knowledge production, we must fit technology to our needs.

Cone volume calculations reveal how much graphite in a standard HB pencil we actually use: even if you use the pencil until it’s completely dull, only about 33% of the graphite is used — the remaining 67% is wasted. If you sharpen it when it’s only halfway dull, the waste jumps to 90%.

You are not wrong, but you are being too harsh. K-means for market segmentation is an *exploratory* and easy-to-interpret way to summarise multivariate data. It's fine IMO, but with lots of caveats, of course, particularly in the questionnaire design.

Saturday morning I ask GPT5 to "tell me something about me" and among the list, I find the nicest of compliments: "Your style is iterative and meticulous — you like to refine, reorganize, and polish — but also boldly synthetic, seeking frameworks that connect ideas across domains"

boldly synthetic

Same pattern for 400m. I have been doing these after each olympiad or world champ.

Just in case there was any doubt that today's 400m final in Tokyo was insane, here I made a chart with the top 10 times in the last 50 years (excluding 2020).

The 1980s were also insane but for other reasons (95% eastern Europe, 50% M. Koch)

2000-2010 is mostly the formidable Sanya Richards.

I took up online chess (around 2017) and Naroditsky was a central celebrity streamer along my journey (esp. post-pandemic). Great commentator of big matches. Such a well-rounded (he had a history degree from Stanford), smart, kind person. These are awful news and I am still a bit shocked.

I love papers that have it all: context, descriptive stats, concrete examples, theory model, public data, private data, tons of figures, empirical estimates, identification, policy implications, etc.

If one works in education, the effect has been immediate and transformative, for better or worse. Homework and term papers will never be the same, even if (after the collapse) we have to live with open source models running on local servers.

Invincible characters are boring and this is among the reasons why *Andor* and *Mandalorian* are better shows than *Ahsoka* and *Obi-Wan Kenobi*.

Same why Batman > Superman

Also why James Bond is insufferable.

I’ve decided not to post my annual “women on the Econ job market” thread this year. Social media has splintered too much, and now that I’ve left academia I’m focused on other priorities.

Ever since I made a video about Fourier Transforms, one of the most requested topics on the channel has been its close cousin, the Laplace Transform.

I've been having a lot of fun animating a mini-series about this topic, and the main part is now out.

But what is a Laplace Transform?

Q: Are men less manly today than they used to be? How?

Brett: I'd say yes. We read about men, particularly younger men, from the 19th and early 20th century, and we're just amazed by their maturity and resolve. They seemed to have quiet confidence that many younger men lack these days. Men from our fathers' and grandfathers' generation also seem to know more basic life and handyman skills, such as how to start a fire to how to use tools, than men in my generation do.

Nobel for metal-organic frameworks!

Could we have had the technology earlier had we not spent the whole 20th century dividing organic and inorganic chemistry into different departments?

Probably something to be learned for the social / management sciences.

Recently heard a youtube exec (in a podcast) saying that the main use of AI in moderation is to protect human moderators from being exposed to nasty stuff all the time.

I wish I had a Jupyter notebook (or similar) of every paper posted or published.

Reasons this is not possible:

- cultural: do not underestimate inertia and
- pdfs give you aesthetic and expositional control
- benefits from intransparency
- lack of common language
- proprietary data

Is it my impression or Nobel Prizes have been increasingly awarded to researchers in the private sector? A good sign in general, but not good news for Universities in terms of relative relevance.

Maybe I should look up if this is even true, but whatever.

I hope this chat control regulation does not go through. It is in principle bad to scan the devices of every user, even if the instrumental objective is valid. The slippery slope and collateral consequences are real.

The European Union Council is once again debating its controversial message scanning proposal, aka “Chat Control,” that would lead to the scanning of private conversations of billions of people. Chat ...
