tbh there's no "best" AI. I think using cursor for scripting with claude code and gemini as terminal options works well right now.

I write spec docs with sonnet 3.7, architectures with gemini, and code with a combo of models. models have different strong suits.

Are you at all concerned about an uprising

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.

It was always a better platform for building.

One thing I love now is being able to implement papers on my own at low cost.

This is a common phenomenon that's not unique to this site. As a reporter, I post things about antisemitism in America as part of my job. The posts do not mention Israel. I will nonetheless get many reflexive replies saying "anti-Zionism is not antisemitism." These people are telling on themselves.

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.

It also strikes me as somewhat bad faith to attack Koch or Arnold here.

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.

#econsky What do we know about “Artificial Intelligence, Scientific Discovery, and Product Innovation” and about MIT's investigation of this paper, which apparently led to expulsion of its author? And what should we change in response. /1

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: 🧵
