jwilber··on We're Missing a Key Reason Why Americans Hate AI
“Everything costs money, but it shouldn’t with AI.”

…

“Below, for paying subscribers, I’ll explain…”

Not sure how this got to the front page (I have some uncharitable ideas), but I suppose low-to-mid quality writing/copy is the one thing that ai has sent to zero, so that’s convenient now!

jwilber··on Goodbye Google
Pick any subfield under the massive domain called “life sciences”.

Or do it as a hobby. I love shooting guns, I certainly wouldn’t shoot people if that was the only way to make a career shooting guns.

jwilber··on Making Startups Powerful
You’re comparing traveling for 6 vs traveling for 1. I can’t imagine booking an airbnb for a work trip.

I’ve booked play airbnbs for eg surf trips with friends. “Guaranteed view/kitchen/remote location” is laughably inaccurate.

The last Airbnb I booked in NYC was literally a bed in a closet with bed bugs. I got my money back (should have received more for the inconvenience and dishonest listing, tbh).

All this is ignoring the egregious cleaning fee they tack on after providing detailed cleaning instructions they make you do anyways.

jwilber··on Why I didn’t sign the Fields medallists’ letter
1. Those early discoveries were much closer to today’s applied mathematics (which many of the pure math academic types sneer at FWIW), and 2. They made those discoveries without public funding.

If AI can bring forth mathematical discoveries much faster than academics, wouldn’t it behove society to use AI? It seems the me the tradeoff here is the benefit of all vs the ego of a few. I empathize with the struggle many math PhDs must be going through, and maybe I don’t fully understand the tradeoff as they see it, but I’m not convinced by the letter written by a few career, tenured academics.

jwilber··on Making Startups Powerful
Yeah, Airbnb has been awful since 2022. Hotels always cheaper, easier, and better.
jwilber··on Magnitude 7.7 Earthquake – 68 km NNW of Ende, Indonesia
Somehow I don’t think people are confusing raw seismic station earthquake counts with the three back-to-back high profile/magnitude earthquakes that recently occurred in Venezuela, Colombia, and Indonesia.

I understand the point, maybe those recent earthquakes aren’t ood, but still.

jwilber··on SpaceX to buy Cursor for $60B
I don’t think mapping tooling to ability makes sense here, particularly when the “advanced” tools here just abstract more away, though I agree that Cursor is terrible. So many useless windows.
jwilber··on The desperation of NYTimes
It was almost impossible to unsubscribe a few years ago. Seems like not much has changed.
jwilber··on Princeton mandates proctoring for in-person exams, upending 133 year precedent
Well, the average grade at Princeton is an A. Not sure how much this will change anything.
jwilber··on Scientists warn Atlantic current at risk of shutting down
You can paste this exact response under your other post, as well. Emotionally compelling, scientifically weak. Worth nothing.

But also, what you wrote is just wrong. There are plenty of measurable, significant, ood effects in the last few decades on the climate and its impact.

Here’s one study onglacier retreat over the last 20 years.

https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021GL09...

And here’s a paper on the effects of the mechanism:

https://www.nature.com/articles/s41558-025-02282-5

I’m sure you’ll read them earnestly.

jwilber··on I'm scared about biological computing
Author clearly doesn’t know the field well at all. First few paraphrases reveal this. Opening sentence: I’ve been in the AI space since ChatGPT first dropped.

Everyone is allowed to have an opinion, but that doesn’t mean they’re all worth listening to. Unfortunately, right now, all of those opinions are about ai.

jwilber··on MegaTrain: Full Precision Training of 100B+ Parameter LLMs on a Single GPU
That’s just playing semantics. Nobody is talking about, “objective facts” or need define them here. If the step time is measured in days, and your model takes years to train, then it will never get trained to completion on consumer hardware (the entire point).
jwilber··on F-15E jet shot down over Iran
Ah yeah, well I didn’t know it was that high!

But I’m responding to the rescue mission comment, which, since Vietnam, have overwhelmingly employed helicopters (Huey’s then, Black Hawks today). But machinery aside, the larger point is that air operations will likely go worse here than they did in Vietnam, unfortunately for both sides.

jwilber··on F-15E jet shot down over Iran
…against the viet cong, where the biggest risk was the pilot getting pierced from small arms fire (in addition to the helo going down from pilot error). Quite different from the anti-air weapons modern day Iran possesses.
jwilber··on Delve allegedly forked an open-source tool and sold it as its own
No shame rewarded as expected in the post-cluely world of contemporary VC.
jwilber··on Nvidia NemoClaw
Fair point, I just think that example is better off running on a cron job than using compute from llm inference, (though that will become negligible over time, anyways).
jwilber··on Scaling Karpathy's Autoresearch: What Happens When the Agent Gets a GPU Cluster
I see this critique about autoresearch online often, but I think it’s misplaced.

Here’s a use case that may illuminate the difference, from my own work at Nvidia. Im currently training some large sparse autoencoders, and there are issues with dead latents. Several solutions exit to help here, such as auxk, which I can certainly include and tune the relevant params as you describe. However, I have several other ideas that are much different, each of which requires editing core code (full evaluation changes, initialization strategies, architecture changes, etc.), including changes to parallelism strategies in the multi-rank environment I’m using. Moreover, based on my ideas and other existing literature, Claude can try a number of new ideas, each potentially involving more code changes.

This automated run-and-discover process is far beyond what’s possible with hyperparam search.

jwilber··on Nvidia NemoClaw
I agree with the sentiment that there are use cases for web scraping where an agent is preferable to a cron job, but I think your particular example can certainly be achieved with a cron job and a basic parser script. Just have Claude write it.
jwilber··on Iran warns U.S. tech firms could become targets as war expands
That has, unfortunately, been business as usual in Iran for the last few months.

But these are all additional points in support of what is already said.

jwilber··on Iran warns U.S. tech firms could become targets as war expands
You really don’t see how the situation is materially different? The bombed oil fields, hotels, dead American soldiers - all business as usual?
jwilber··on Decision trees – the unreasonable power of nested decision rules
Looks great, if I remember correctly the author mentioned that the spring color palette + fruit examples are a bit tongue-in-cheek.
jwilber··on Layoffs at Block
Or empathetic, especially when they throw money away à la $70M parties:

“General and administrative expenses increased by $68.1m ... The increase was primarily driven by … an in-person company event held in Q3 2025”

jwilber··on Layoffs at Block
Some choice Jack Dorsey quotes:

From New Yorker profile: “His goal… is… by making information freer, he hopes to make the world fairer, kinder, and nicer.”

Where he also writes, “I definitely feel the most fundamental issue is economic equality.”

But hey, the stock is up 25%!

jwilber··on The Om Programming Language
Will never not complain about languages not giving code examples. It’s like writing a charting/UI/style library and showing no examples. Just what?
jwilber··on Trump says Venezuela’s Maduro captured after strikes
The Venezuelan people?
jwilber··on My role as a founder-CTO: year 8
You must be fortunate to have a lived experience where the answer isn’t immediately (and obviously) financial security.

Also: plenty of meaning outside of running a SaaS. Hell, undergraduate research assistants probably contribute more to societal at large.

jwilber··on He set out to walk around the world. After 27 years, his quest is nearly over
The article didn’t even mention that, at 29 years old, he abandoned his 5 year-old son to go on his middle-aged crisis journey. Some person to celebrate.
jwilber··on Why are 38 percent of Stanford students saying they're disabled?
Would love to see the percentage of Forbes 30u30 who also had (sorry, claimed) a disability in college.
jwilber··on High-income job losses are cooling housing demand
You work in tech and are somehow convinced working on a blockchain app is a good thing? We should make employees pass a basic economics test!
jwilber··on µcad: New open source programming language that can generate 2D sketches and 3D
Yeah, my guess is the team vibe-coded it because wow is does it have poor performance /is difficult to use. A few links didn’t even work for me…
