LAST WATCHED: SISU 2: ROAD TO REVENGE (2025) is, sadly, a more conventional film than the original. Still lots of bloody fun, but too similar to the original in its beats to be as enjoyable, trying harder to be “emotional” while losing some of the little textual depth that made the first film surprising.
fossil fuel money is an immensely powerful, intensely corrupting force in American politics that limits not only what conversations we can have about massive problems, but what we can do to solve them
But if you ever want to get better at anything, and sometimes that depth, that nuance is the thing that leads to an invention, right? If you know how a compiler works, if you know how memory management works, that might give you enough information to say, "Oh, I can make a new programming language."
and I don't think it's possible for one person to understand everything in depth. Lots of people understand broadly a lot of these ideas but they don't understand sort of everything in in the depth that is actually utilized. That's why there's these, you know, papers with with well over a thousand authors.
We may have a handful of genies, but that's different from having a handful of friends, right? In part because the energy's different, the conversations are different. Also, they just agree with us constantly.
Yeah, so they excel at breadth and humans excel at depth. Um like human experts at least. Yeah, so um I think they're very complementary. Um but our current uh way of doing math and science is focused on depth because that that's where the human uh expertise cuz humans can't do breadth.
Overcommitted: Put simply, thoughtful tech conversations from thoughtful tech people. I'm biased towards this one because it's run by some coworkers, but they are awesome coworkers and it's fun and interesting!
the depth of a coffee bed, contrary to the width of the coffee bed, is a variable that impacts the flavor of the coffee being brewed significantly, and in a way that you cannot easily compensate for by changing other brew variables.
And a thousand experiments by itself, like if you just did that, but you didn't learn, you didn't make an impact, and that's kind of a waste of time, right? The whole point of setting a goal is that you can have conversations about what would need to be true to actually hit that goal.
Brett and I like betting and one of the bets we have is the year in which greater than 50% of conversations with agents built on Sierra are with people's personal agents. So agents talking to agents.
Recently I reviewed Adrian Kind’s 2025 book, “How Does the Psychiatrist Know?: On the Epistemology of Psychiatric Diagnostic Reasoning,” on this substack. I had mentioned that Kind’s book is the first systematic, in-depth, book-length philosophical investigation into how psychiatrists arrive at their diagnostic conclusions.
Eventually, I think it’s kind of hard to imagine, but yes, all of these Nobel Prizes, all of these mathematical proofs, all of these conversations, all of these ideas, all the influence we have on each other, even the AI, eventually will expire.
When I have conversations with breached companies, my messaging is crystal clear: be transparent and expeditious in your reporting of the incident and prioritise communicating with your customers.
A collection of short essays and aphorisms on crafting a life of autonomy, creativity, and intentional leisure—challenging hustle culture with elegance and philosophical depth.
"It’s honest in how it covers topics like navigating tricky power dynamics with CEOs, surviving 'peer panic,' dealing with competition within leadership teams, and in its overall breadth and depth."
C# is the language I probably understood down to the nitty-gritty details. Just when I thought myself of being an expert - knowing all that is to know on memory allocation, garbage collection, LINQ - I read this book. It made me realize how many things I did not know.
The practical impact is that the vast majority of one-on-one Telegram conversations — and literally every single group chat — are probably visible on Telegram’s servers, which can see and record the content of all messages sent between users.
The bar I typically suggest is that the people manager doesn't need to have the most technical depth on the team, but they need enough depth that they can follow most discussions without slowing them down, understand who's correct in most debates without needing to rely on trust, and generally stay oriented easily.
Briefly, James is Huckleberry Finn retold from the perspective of Jim. It has all the energy and humor of Twain's work—in Everett's own unique voice of course—and adds a whole new level of depth to the story.
Gergely brings an incredible amount of reporting depth to every edition of this newsletter about the nuts and bolts of building technology. A must-read for the tech rank-and-file and their managers.
I had read Johnson-Laird's original work, Mental Models, last year. It was nice to see an in-depth follow-up on how the theory has developed in the subsequent two decades.
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com.
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
