That whole thread feels like something out of Black Mirror. Especially the comment from Claude AI right under the OP’s post summarizing the thread. The dark humor of the juxtaposition of Claude AI’s harsh summarization of all the users’ pain….pure Black Mirror.

I think this would depend on the intersection.

If the lights are at an intersection where a very busy road crosses with a less busy road then turning it into a four way stop just turns it into a traffic jam on the very busy road. I’ve seen this happen during rush hour in the United States multiple times.

When it’s not rush hour though maybe the situation is different? Not sure.


Flock was a startup that was funded by Y Combinator. Paul Graham and the other Y Combinator people provided expertise and advice to them throughout their whole journey.

I wonder what Paul Graham says to the Flock executives now?


In case anyone's wondering (I was). Flock was in the summer 2017 batch and more recently YC invested in their 2025 raise.

It's not PG, it's Garry Tan.

And Garry Tan has repeatedly defended Flock and badmouthed people who oppose them.

PG is still involved in Y combinator batches and all that right? He regularly posts about giving advice to founders on his twitter account.

Here is a link to the original article:

The original posted link from OP is from Terry Tao’s website where the article was posted as a guest blog post.


It's astonishing how much more readable Tao's version of it is.

That's what I thought also, that is why I posted Tao's version.

I have fond memories of reading National Geographic magazine growing up. I remember they had memorable issues with King Tut. And Ancient Egypt in general. Made me fall in love with learning about Ancient Egypt.

Anyone else here have fond memories of reading those old National Geographic issues?


Absolutely. Extremely formative to my early years.

Yes, I do, although I noticed that I had a hard time reading the text, the images were so interesting.

Are you sure about this? If you look at the ancient stories in India you can similar phenomena

Yes, Jaynes used a comprehensive approach, albeit one rooted in literature. I only threw in "Homer" as an example to be clear that "ancient civilizations" referred to bronze age and before, and that this was not the Joe Rogan kind of ancient civilizations.

I think the trouble is once your category is loosey-goosey enough it could be open-ended to the point that anything can fit it.

The fact that overall of recorded history you can find instances of any sort of interaction with something that's felt to be a voice that's independent from one's own subjectivity is open-ended to the point that it can fit the literary and cultural history of basically any civilization on Earth.

What would be more impressive is some additional specificity, any sort of evolutionary mechanism, and any sort of supporting biological data. Otherwise the thing that is being described here isn't a theory, it's barely even vibes. This is to vibes what vibes are to coherently formed thoughts.


This seems like a pretty catastrophic failure on Amazon’s part. It seems pretty incompetent actually. You should have multiple copies of your customer’s data across multiple locations.

And these multiple locations should be in different parts of the world. Not concentrated in one highly volatile region.

All this seems like common sense to me honestly. Anyone with more knowledge than me know why Amazon didn’t do this?


AWS go to great lengths to explain what Az replication Vs geo replication means in clouds. "All the AZ zones get knocked out" is down to the end user to decide if they want to pay the extra for geo replication and do the paperwork etc to address that risk.

This will definitely surface which people were serious when they said "YAGNI"

> And these multiple locations should be in different parts of the world. Not concentrated in one highly volatile region

AWS can't make that call unilaterally of copying people's data to other jurisdictions while also keeping to promises of data hosting and legal sovereignty. That aside in the future there'd be some horror that takes out n regions and we'd be back here saying "why oh why didn't they replicate to n+1 regions"

It's definitely a long tail event of full data loss/the kind of thing people make jokes about over paranoid resilience planning "what if someone nukes Virginia though?" but it's 99.99999% likely in the Ts & C's


> This seems like a pretty catastrophic failure on Amazon’s part. It seems pretty incompetent actually. You should have multiple copies of your customer’s data across multiple locations

How much of it is due to Amazon VS due to regulatory reasons (have to host data in particular region) VS customer self-serve have to choose redundancy across regions?

My quick read through the article didn’t surface an answer to this, but it is very possible I missed it.


You have to pay for that. Some people want to pay less to not have that.

multi region data distribution is available for customers, but it costs more

I put this on the users


Something about this article seems suspicious to me. It’s this part:

”It’s difficult to sympathize with people making a combined income of $365k, which places them comfortably in the top 20% of San Francisco households.”

If someone without household income in the top 20 percent cannot find a place to live in that city…isn’t that a catastrophic situation? I mean these people were looking for a simple apartment and couldn’t find one. That’s…highly concerning. Their story shouldn’t be dismissed.


That's more of a problem for the tech workers themselves, their fellow commuters clogging up the road, the companies who employ them, and the city (long-term, the city becomes stagnant and ossified). But that's not a problem for the landlords of the city, who benefit from the massively inflated rent they can charge.

The only restriction currently[1] in place on newspapers in the United States is that you cannot write libel i.e you cannot knowingly falsely write something that hurts another’s reputation. This is the same restriction as in verbal speech where you cannot say slander which is like libel but spoken.

[1] There have been other restrictions placed at various times but these other restrictions have over time been found to be contrary to the First Amendment.


Are you sure the attitude changed generally or did it change more specifically here on Hacker News? Perhaps the kinds of people who use Hacker News changed.

Go to the 2:00 mark of this interview. Sam Altman says “Paul Graham is the most important force in startups of the past few decades” and the whole auditorium starts cheering. So Paul Graham is akin to a god in some places.


I would hazard a guess that the people attending a YC event (!) to watch Sam Altman (!) talk with Garry Tan (!) would regard Paul Graham well irrespective of how the rest of the world sees him.

> Perhaps the kinds of people who use Hacker News changed.

I don't think that a change in the composition of HN users is sufficient to explain it. To start with, a lot of the original user base which came over from main Reddit and /r/programming still seems to be active here. And if I had to hazard a guess I'd say that our attitude to pg has indeed shifted.
