This is peak delusion.
Human level intelligence is the most precious and valuable thing on the planet, and as far as we know, the universe.
The ability to make more of something like it is pure magic. And the most significant thing we’ve ever invented.
The TAM for AI is trillions of decisions per second. Nearly every decision being made in the world.
The AI bubble bursting is going to be one of the biggest reality checks in tech history. These companies have spent years convincing us that AI is the future while burning billions, destroying jobs, draining natural resources and forcing products nobody asked for into our daily lives. Eventually, the hype has to meet reality.

Java is a language that arrives late to things. Let me prove it: lambdas, records, virtual threads, generics. Many other languages had them long before.
Now you might be thinking:
- Elder, are you trashing Java?
- Quite the opposite. To me this is one of Java's big advantages.
Before I tell you why, think of a company that's an expert at arriving late: Apple. It wasn't the first to launch a tablet, or a smartphone like the iPhone, or an iPod. It always got there later. And what's the advantage of arriving later? You get to avoid the mistakes others made.
A great friend of mine says Java has always been a production language.
- Yeah, but every language is a production language.
- True, every language is made to put things in production. But not every ecosystem has the culture of looking at production before shipping something. In Java that was always priority number zero.
The practical consequence? Lambdas, records, virtual threads, generics, and plenty of others went in without bugs in production. You won't find stories of "wow, records blew up in prod because they got the implementation wrong."
I've been at this for 27 years and I don't think Java will ever race to ship something before other ecosystems. And to me that's a career lesson too. Do I really need to rush to be the first to do something? I don't know. Looking at a language with over 30 years in the market, still evolving like no other, I think they know what they're doing.

I find it bizarre that so many open-source projects have posted policies against AI-assisted contributions.
This will not last, because they'll be outcompeted by projects not afraid to use power tools to debug the code and and features. In crucial cases, AI-hostile projects will be forked to remove that restriction.
How can anybody not see this coming?
This dynamic is so obvious - and anti-AI rules so patently futile and doomed - that I have to conclude there is something like a religious frenzy going on.
I'm going to bend over backwards to be fair about this. There was a point earlier in the development of AI at which such restrictions might have made temporary sense, because model outputs were prone to enough noise and hallucination to be a net drag on productivity.
We're long past that now. And the obvious solution to merge-request queues flooded with AI-generated slop is to use AI to filter them so exercising human judgment on the remainder remains practical.
I'm not going to argue rights and wrongs here. One might just as well argue that it's wrong for sandcastles to collapse when the tide comes in.
The religious frenzy does bother me, though. Maybe less than it did 5 minutes ago when the mind infection was "wokeness", but a mob of crazies is never an edifying or reassuring sight.
I guess the most positive thing I can observe is that this phase of nuttery won't last long, because it can't. The selective pressure against it is too brutal.
It does leave me wondering what cause the nutters will attach themselves to next. Alas.

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵

Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math.

AI may well be able to write massive software projects “from scratch”, but that almost certainly isn’t the fastest / highest performance / highest security / most token efficient way to do things. Good building blocks matter.
In addition to RL’ing the agents on final task loss, we should try to get them to regularize the building blocks as well. What would the standard library look like that makes the agents most effective?
It is likely at the limit that it turns out to be some alien organization of code, but given the existing human-bias in training, I bet that in the near term it would be lovely code that old programmers would appreciate.
I suspect the same could be said for mathematics, but that is out of my lane.

I'm starting to sense a divide in the tech industry:
- People thriving on autonomy who are reinventing how they work and what tools they use with AI: LOTS of work, but they're enjoying it and getting very efficient
- People used to being mentored / trained / or simply told what to do and how. Frustrated with the lack of guidance from management on what to do with AI; also frustrated by seeing some of their peers thriving; increasingly bitter about AI and the state of the industry, as a whole
Neither group seems to be aware that there's another group, or have empathy for the other group

JetBrains IDEs are now powered by libghostty! This brings huge feature and performance improvements to JB terminals! Based on their own annual reports, that's over 12.5 million active users across all platforms about to get a libghostty-powered terminal. blog.jetbrains.com/platform/…
I'll repeat myself: libghostty is and was always the primary goal of the Ghostty project (I said this in the first public talk I ever gave about Ghostty). The importance and impact of a free, liberally licensed, high quality terminal emulator library that runs anywhere and everywhere dwarfs any single terminal emulator application on its own.
I've estimated Ghostty's (GUI, not libghostty) own users at around a couple million. Overnight, 6x that are using a libghostty-powered terminal. From one integration.
Happy to see this, happy to hear JetBrains had a positive experience, and looking forward to continuing to improve and ship a stable libghostty tag soon!

We should be more ambitious with the software we build:

If I didn't know Malis and didn't look into it, I would just assume that pgrust was another vibe slopped project that's never going to work. But I know Malis well enough to trust his work without looking into it, and if you look into it a bit, you'll see that in testing pgrust, he's testing thoroughly enough that he's even uncovering real bugs in Postgres, such as this numerical bug that can cause valid SP-GiST operations to fail, this format cache bug that can cause incorrect results from JSONPath, this pgcrypto bug that can cause later operations to fail, multiple memory safety bugs in the dictionary loader, this money overflow bug, etc. This isn't to say that pgrust i...](https://pbs.twimg.com/media/HVbOGdKboAAAbtO.png?name=orig)

If you hang out with happy, optimistic, and ambitious people, it'll rub off too. That's why pruning your social media algorithms is so key. Don't psyop yourself into a depressive hole.

AI makes your work harder, not easier. I think of it as work density—the percent of time spent expending brain cells. The denser the work, the more exhausting it is. If you have 10 agents running at once, you have 10x the context swaps, each of which requires recovery time. The more density, the higher the recovery time. When you don't take time to recover, you burn out. Working with multiple agents is worse than normal multitasking because you're juggling more tasks.
There's nothing new about this. I can't think of a single "time-saving" workplace technology that saved anybody any time. Instead, it forces us to work harder. It increases density. The problem is compounded by moronic management that fires people because of the tech. In practice, firing 50% of your staff means that the remaining 50% have to do twice the work in the same time. It's exhausting. The utopian notion that AI will create leisure time is complete BS. It will just force us to cram more work into the time we have.
We need to just stop frantically pushing, pushing, pushing for more and more output and relax. It takes a conscious effort to counter that effect, so make the effort. You will not be "more productive" once you burn out.

Linus Torvalds says, rules prohibiting AI usage are “UTTERLY STUPID” and “idiotic”.
For the Linux kernel, Torvalds says, “we’re not going to make stupid rules that say ‘you can’t use tools for X’”.

you might be the first person talking about the data over the architecture! 🥲
we consider ourselves a data research lab! the vast vast vast majority of research was on making data that is truly general (ala a cognitive core) and 100% of our data is synthetic (but not the type of crap that is just spit out from an LLM obviously)

The key point is to recognize that the more you care for others the greater will be your own sense of peace. It's quite clear that where there is less kindness in the world, there are more problems. When we talk about love, kindness and compassion, it's not a religious matter. It's part of the fundamental reality of relations among social creatures.
