How will AI reshape jobs—not just replace them? Daniel Rock, 2023 AI2050 Early Career Fellow at Wharton, studies how AI transforms individual tasks within jobs and is building a model to track those shifts. Read the Q&A: ai2050.schmidtsciences.org/community-pe...

gonna drop this platform for a bit. take care everyone.

Feel like there are a lot of folks on Bluesky who need to read this paper.

Common AI failure mode is to ask it for what you want in the end. One day that’ll be doable generally… only sometimes it works now. For now ask for code that generates what you want (where applicable). This is true for training ML models too… learn the DGP then transfer to other target/outcome.

Full automation of code is a choice, and I don’t think it’s one that’ll be made in most firms. By percentage of code written, sure, machines will dominate. but you know what’s complementary to shitloads of new code? Talented developers.

For those who don't know this story, which I first shared six years ago today.... This one time I got my days wrong at work and ended up alone in a room with my boss and the President of Ireland while I was on ketamine. 🧵

My perspective on vibe coding vs real coding

I'm a current Harvard graduate student and I found out today that I had my NSF GRFP terminated without notification. I was awarded this individual research fellowship before even choosing Harvard as my graduate school

People don’t realize the reason bond ratings matter is that they’re tied to regulations and policies with margining requirements. You really don’t want the BBB- to BB+ change.

Shingles is terrible. Get the vaccine… it’s not just a disease older people get.

Let's talk about these two department store owners: brother and sister Louis Bamberger and Caroline Bamberger Fuld. From Newark, New Jersey. They are random people, basically. But in the late 1920s, with fascism taking over Europe, they made a choice that profoundly changed the world: 🧵

Who is this mathematician and why is he using AI to cheat??

This is fucked and wrong

While I understand the sentiment, I must disagree. We are already required to do too many different things at a high level. Communicating with the public is not an easy skill and requiring that students be good at it is in some ways another barrier. Instead, make a podcast with NotebookLM!

This is a fucking unwelcome discussion

Farewell Pat Bajari. What an amazing legacy he has left opening up the PhD economics path way like no one else has.

I'm a little annoyed that Amazon isn't offering prime shipping right now on Hate the Game, but I also know that must mean they are out of stock and resorting to third party sellers, which is a good sign. Hate the Game is in stores so you can get it today! Thanks to everyone who has ordered so far!

honestly relieved that 9 of 9 justices were like “randomly grabbing someone for no reason and sending them to a foreign gulag is not, actually, justifiable in our legal system”

Huge huge kudos to @anthropic.com for releasing this detailed overview of how students are using AI. Some pretty concerning trends here, such as students completely off-loading higher-level reasoning to LLM and mostly prompting for direct answers. www.anthropic.com/news/anthrop...

@manuelacollis.bsky.social @clemvaneff.bsky.social this is such great work!

Lmfao 🤡🤡🤡

Seeing a lot of cope on here and the bird app about how Trump is gonna change his mind or this is some tactic. This was what he said he would do! He thinks it’s a good idea. Don’t count on a reversal imo.

You can simply *do* things

Market moving a year in a day

Six weeks ago I predicted a very negative March jobs report. That report comes out Friday. I no longer think that we will see massive job losses in that report. I still think a recession is coming (and the markets seem finally to be coming to agree with that), but not as quickly as I first thought.

Yesterday I vibe coded from scratch in 4 hours an R package that took me 4 weeks to build a while back

As bizarre as this seems, there are major limits to interdisciplinary work along these lines. A seminar I used to attend in grad school sometimes would spend the first 20 min of every talk asking the speaker to “justify the philosophical approach”. It’s tedious and unhelpful for learning.

Happy anniversary to one of my all timers from the bad place.

Excellent work by new NYT headline writer Werner Herzog

Never forget, a 13-year study found that protected bike-lanes led to a drastic decline in fatalities for all road users. ALL ROAD USERS. And painted bike-lanes? No safety improvement at all. For sharrows, it’s actually safer to NOT have them. Via @usa.streetsblog.org @nyc.streetsblog.org

This is horrible to post, but I may as well post it. We are essentially shutting down research operations in my group, which is focused on treatments for pediatric brain cancer. I’m a well funded investigator, and there’s no choice. Science can’t function without the stability of NIH

we are looking for an Associate Professor (tenure track) in applied Economics, pls share: www.timeshighereducation.com/unijobs/list...

Wonderful view of yesterday's Ariane 6 launch courtesy of the French air force. Not much outruns a fighter jet...but a rocket does just that!

Ostensibly this is about protecting Jewish students. Given the demographics of Columbia University, I suspect withholding $400m of funding from the institution will hurt a lot more Jews than it helps. www.washingtonpost.com/education/20...

This doesn’t make sense. There’s a very big difference between Mitt Romney and Trump.

James Harrison, a blood donor famed for having saved the lives of more than 2 MILLION babies, has died. Harrison’s plasma contained a rare antibody known as Anti-D which was used to manufacture a medication given to expectant mothers. Harrison donated plasma every two weeks from age 18-81

Randomized trial AI for legal work finds Reasoning models are a big deal: Law students using o1-preview had the quality of work on most tasks increase (up to 28%) & time savings of 12-28% There were a few hallucinations, but a RAG-based AI with access to legal material reduced those to human level
