So when @Honeycombio CTO Charity Majors set a productivity target, she didn't chase 10x. She chose 2x, & built from there. Related

So this is the task-based model jobs where you have like a lot of different tasks. So like a doctor, what is their job? They're filling out insurance documents. They're you know, going and like calling different pharmaceutical companies. And one of their tasks is to actually see the patient and talk to them, but that's like actually not the main part part of the job.

I do think there's this qualitative shift that we I think we agree is coming, which is that there will be at least some goods whose network-adjusted capital share goes to one, right? Because the whole supply chain can be automated and there's no part in it that we care intrinsically about having a human do. Um, so that'll be a, you know, that'll be a qualitative shift.

there's a sense in which nothing's yet been completely automated.

You'll find that labor's adding a lot of value down the supply chain.

Unfortunately, I completely agree that the United States of America is rapidly descending into all-out conflict between left and right. The Luigi left, Kirk killers, anti-Tesla terrorists, and Altman attackers are already in shoot-on-sight mode against conservatives, libertarians, and technologists. The right isn’t there yet; they’re called reactionaries because they only react, so they’re always one cycle behind. Thus, the left has already started shooting while the right is still “only” mirroring the lawfare of last decade’s left. But anyone can see how incandescently angry the American rig… Quoting @romanhelmetguy Gonna try to explain this to tech CEOs again: Young Americans are pissed. They feel betrayed.

I still meet people convinced that AI coding tools will soon reach a point where code quality, design, and even architecture are "solved". So I ran a small ad-hoc experiment. I’ve been working on a CLI tool and let agents plan and implement a first functionally correct version. I provided strict instructions around testing strategy, workflows, and implementation constraints. But I deliberately removed the @codescene MCP and the safeguards I normally rely on. Unsurprisingly, the resulting code suffered from a ton of problems. It would have been a shaky foundation to continue building on. How s… MCP Related

Why Rust is different, with Alice Ryhl
5 beliefs, in the piece's order there
Their words
I think this is kind of leads to another way that Rust really helps with reliability, which is that if you're refactoring, I think Rust is really good at telling you all the places you need to update. I've done this sometimes where I would refactor something. I change the code. I change the return type or whatever it is, and then I just fix the compiler errors and until the compiler stops shouting. And then once I've done that, I've updated every place I need to update.

Freelance research analyst and writer of the blog Aceso Under Glass, known for 'epistemic spot checks' of non-fiction claims.
Nothing matches. Show everything
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.
