My support for bluesky/atproto is pretty much explicitly a "political" project. It is bad for a small number of (mostly right-wing) people to literally own all the sources of media. Open-source algorithms + the ability to move your account without negative network effects opposes this.

My lukewarm take is that when people disagree about whether LLMs can do X (be it reasoning, creativity, etc), the substantive disagreement is really about what X means, rather than about LLMs themselves. Aka Wittgenstein was right

Pairs well with the timeless call for "distillers" to ensure we do not fall prey to research debt: distill.pub/2017/researc...

LOVE this question: "...why should...“non-credit-producing activities” [like lucid motivating explanations or mathematical education] follow a [highly prestigious award for mathematical contribution like the] Fields Medal, and not contribute to it?"

Quote from Bill Thurston describing "non-credit-producing activities" he values just as much as proving theorems:

I have put a lot of effort into non-credit-producing activities that I value just as I value proving theorems: mathematical politics, revision of my notes into a book with a high standard of communication, exploration of computing in mathematics, mathematical education, development of new forms for communication of mathematics through the Geometry Center (such as our first experiment, the “Not Knot” video), directing MSRI, etc.

And accompanying question from Grant Sanderson:

Again, why should these “non-credit-producing activities” follow a Fields Medal, and not contribute to it?

Insightful keynote from Arfon Smith at RSE: semble.so/url?id=https...

h/t LinkedIn :)

This bit made me jump up and cheer, a phrasing of a powerful idea worth holding onto tightly:

**We must avoid scientific trust becoming a subscription product**

I'd vote for the future where there's the option of a box that pops up when lazy nonsense appears and says "this looks like AI slop. Would you like me to find a piece written by a thoughtful human on this topic - something that's valued by other humans and is actually worth reading?"

"In Referees We Trust" will be open access and available October 13 -- but for those who prefer physical books, Barnes and Noble is running its preorder deal again! Members can get 25% off all preorders with code PREORDER25 through September 11.

Rakow’s new paper found that “around 90% of articles that discuss replication and over 80% of articles with author-identified replications are missed by searching databases for replicat* because databases hold few details per article”. 8/

I wonder if this (i.e., scholar-created and maintained, openly governed, computational open science infrastructure) will open pathways to more nimble evolution of the fitness landscape, which could itself be a defense against ossified gaming of the system (as in h-index, journal prestige, etc.)

Like @devezer.bsky.social says, science is a social process. Which is both beautiful and also… not so beautiful.

Yikes!

Added some discussion to a @semble.so collection as an additional discussion bundle for the paper: semble.so/profile/joel...

One of my favorite features on the Lea app: collating discussions of papers! Beautiful companion to @semble.so for social sensemaking of science.

Check it out! https://bsky.app/profile/did:plc:5wm25vgenhgut3iqfjf4ozj5/post/3msvs2hxmvc23

Alas, no! I recall our conversation fondly. I'd love to reconnect though! Will follow up in DM.
