Right, to do that you’d have to write a lot of specs and a lot of tests. Which is doable but a lot easier when you’re building them organically alongside a small code base.

Admittedly the only places I’ve ever seen elephants in the street were NYC and Coral Gables Florida, but I stayed mostly in bigger cities in India :)

The 2nd project’s code will almost certainly be better. Even if all 400 of the LLM PRs are rejected, building the testing and analysis flow to handle that will mean better code. But that’s going to be a hell of a hill to climb for existing projects (and their under-appreciated, unpaid maintainers).

Eg I saw this week a FOSS project that had received 400s+ LLM-filed bugs over the weekend. Existing FOSS projects will rightly say “fuck that”. But I’m already seeing projects that will just feed that to their own LLMs and CI processes for validation (or rejection) before humans waste a second.

Human drivers do it all the time to indicate in busy crosswalks that “yo, I gotta get across eventually, let me through”. Or when they are on their phone and not paying attention, or just irritated that pedestrians exist at all. Waymo only does the first of these.

The Waymos in S.F. are both reading cues and cueing themselves, and have been for about a year. But it is problematic (many “driver” cues are literal violations of the law, like nudging into the crosswalk) and no idea how they’re thinking about working across car cultures.

This is why I think on net, going forward, LLMs are a huge win for software quality. But the backlog is immense and lots of our supply chain will (rightfully) say “fuck it” and walk away.

A friend worked on reverse-engineering the Apollo heat shields for the new capsules. Lots of the learning boiled down to “whoa we can’t manufacture that anymore because it, and it’s manufacturing process, was mega-toxic to all forms of life everywhere“

Judges in particular. Why ask for a tough sentence when the judge drove to work, almost certainly speeding the whole way, today? (Same problem, sad to say, as sentencing and “boys will be boys, why ruin their lives” rape culture.)

It is both great that these passed and utterly damning that this is the best we could get. The last two in particular in any sane society would be ”never drive again” rather than debating how many points on a license or how long the suspension is.

This research is important not just for the copyright nerds. It’s a great example of informed auditing to help society understand the implications of LLMs. Bluntly, governments should never use models that scholars like @afedercooper.bsky.social can’t audit.

Body and car count of just news from @sfchronicle.com and @missionlocal.org just this afternoon, just in SF and the peninsula, just those reported: three dead, 12 or 13 cars trashed. We need a plan to ban human drivers, which means we need a plan for transit, bikes, and yes, AVs.

And it isn't *very* visible in public, but you can see it in the less-than-confident responses to questions about "do you really need to inch into the crosswalk" as opposed to the still very-confident messaging from them on safety generally.

Luis Villa @lu.is · 30/09/2026
You can now also see the reverse: Waymo has realized "oh, maybe strict adherence to every traffic law is not very workable" which means suddenly the philosophical questions are waaaay more complicated.

I like this framing of LLMs as "intelligence amplification". For Wikimedians and Wikipedia, the question is where are humans involved: still subject to the healthiest and best of our community constraints? Or does that migrate fully to big model providers? backofmind.substack.com/p/because-i-...

There's a lot of the same deep puzzle-solving motivation for AV people, but (1) the hard physical constraints tend to ground people, so that it's more "passionate vocation" and less "religion"; (2) at Tesla in particular, lots of those deeply curious people have fled due to Elon being Elon.

But I think that core fact fundamentally means the discussions start in different places.
1120
Luis Villa @lu.is · 29/09/2026
AV also has more concrete notions of safety: are people dying? The LLM safetyish discussion operates largely in fantasylands of future hypothetical harms. This is oversimplified; obviously the FSD people don't give a shit about body count and some AI safety people discuss present-tense IRL harms.

It wasn’t so much his personal 9/11 as it was vice-signaling to his oligarch buddies. They wouldn’t shut up about it, because they think all their employees are stupid and woke, and dislike any binding constraints like “maybe you shouldn’t be racist. He was echoing them.

I suspect that best practice separates identity from keys, since if someone blocks a key you don’t want the entire identity blocked? But maybe that’s the low-risk, low-effort option?

Or rather, for anonymous APIs. Many of the best open properties can be had from keyed APIs. (But we don’t have much of a coherent theory of which/how).

the track record of boring ol un-revolutionary politics is, to be fair, not great in the US of late! But the track record of revolutionary politics in the US is basically a graveyard of noble ideas since the IWW more or less.

That actually also defines the US at the current moment, so I think you left out an important “thinks things can be improved”. But yes, Japan.

All the carbon and pollution concerns boil down to “so you should work like hell to elect a party that cares about those issues; demand they fund and staff enforcement agencies competently; and demand streamlining and prioritization of enforcement.” But that’s hard to get angry about online.
