They should have taken the opportunity to combine the Stanford Prison Experiment, the Stanford Marshmallow Experiment, and the Stanford Linear Accelerator into a show where people assigned as guards or prisoners are repeatedly bombarded with either one marshmallow now or two marshmallows later.

Honestly, no. He's savvy enough to know that such a comment would be "misconstrued." Hence, he meant what he said, and that's not reassuring.

Honestly, I find this sort of PR (because that's what it is) really puzzling. OpenAI is basically telling its potential customers that they can't be trusted to secure their own systems. How can said customers feel comfortable sending their most sensitive data to OpenAI's models?

Actually, come to think about it, you're quite right. Many of us literally grew up in Milan, too! I can certainly think of Bocconi people who are not decision theorists and did not grow up in Milan, but as far as (twentieth-century) decision theorists are concerned... hmm, interesting!

Marciano Siniscalchi @marciano.bsky.social · 15/08/2026
Also, "from Milan" is a bit ambiguous. "From Bocconi" would be more accurate (and correct for us GenXers). Yes, contrary to popular belief, there are other universities (with econ departments) in Milan!

I'm not really aware of anything worth reporting... things may be different now, but growing up in Milan, there were relatively few Chinese restaurants in Milan, and none of them good, so I went very rarely. I remember very standard fare, nothing imaginative (even in a bad way hahaha!)

Please ELI5: how exactly is this different from following a science-related feed (other than LaTeX - yay! - and longer posts)? That is, do I get to follow different people on Lea and on Bsky? Do my posts on Lea appear on Bsky too and vice versa? Maybe a short explainer might help others too! Thanks!

I agree 100% with this. We are still learning how to best use these tools, and so it makes sense to take a cautious, yet open-minded approach.

Marciano Siniscalchi @marciano.bsky.social · 07/08/2026
These are all fair points, but just to clear the air, the idea AFAIK is simply to provide the AI version of "technical referees" whose task is to spot issues with proofs, etc. What difference does it make that it's an AI rather than a human (other than, potentially, the quality of the review)?

Marciano Siniscalchi @marciano.bsky.social · 07/08/2026
Are you worried that referees will be less careful about technical details? It's possible, but the fact that these tools are used after conditional acceptance makes things ... interesting: what is the AI catches an obvious flaw that you, a referee known to the editor, did not spot?
100 1
Marciano Siniscalchi @marciano.bsky.social · 06/08/2026
Also, Refine reports will be treated similarly to regular referee reports: editors can highlight only certain points, and of course authors can object to the points raised. BTW, since AI is intrinsically random, running Refine twice need not catch the same issues (except for glaring ones). 2/2
120 2
Marciano Siniscalchi @marciano.bsky.social · 06/08/2026
To clarify, as far as ECMA is concerned, Refine reports will be offered at the cond'l acceptance stage, so there is no strategic advantage to running Refine before submission (though I would personally use it-or similar tools-to improve quality). 1/2

In principle, sure, but the economics are against it. Suppose you use an LLM to go from prompt to binary, and spend X dollars in tokens. If you literally only keep the prompt and the binary (no intermediate product) every time you want to add a feature, your cost is again on the order of X dollars.

It's even worse. I was talking about this with a colleague in Italy. Even with an in-class exam, you need to worry about hidden second phones (yes), watches, even glasses. Her institution considered blocking cell signals but apparently that's illegal bc it can cause interference outside the building
