The biohackers subreddit banned all posts about peptides and HRT because peptide companies were spamming + manipulating the sub in order to manipulate Google AI and ChatGPT answers. Very insidious industry that is drastically changing the internet www.404media.co/companies-ar...

New post: Can longevity save us from a population crisis? We tried out @ourworldindata.org’s new population projection tool to see if increasing life expectancy could save us from demographic decline:

Great overview of current best practices for agentic coding tools. Recommended reading if you write code. steipete.me/posts/just-t...

Things I find surprising about AI in Sept 2025: - lots of progress on coding agents, little on game-playing - really great writing is still beyond LLMs, no real progress since 4o - AI generated videos are really convincing now, but fake AI content is not flooding my timeline yet

Excellent thread on AI by my colleague Esteban - recommended!

Childhood leukemia used to be a death sentence for the vast majority of patients. Now, most children in rich countries are cured. Cool article from @scientificdiscovery.dev for @ourworldindata.org on crucial progress I was completely unaware of: ourworldindata.org/childhood-le...

So far we’ve been lucky that LLM economics results in almost perfectly egalitarian access to capabilities. It could’ve gone differently - where the richest enjoy far better systems or one lab holds a monopoly. Here’s hoping this stays true.

Really nice to see these features in prod! Kudos to my colleague @sophiamersmann.bsky.social for building all of this! 🔥

According to SimilarWeb, chatgpt.com had 5.1 billion visits last April (13% increase relative to March), and about 55% of the visitors were younger than 35. For comparison: Wikipedia.org had 3.7 billion visits (down 6%), with ~45% under 35

“…today’s antivirals are so effective that if taken during pregnancy, the risk of passing HIV to the infant is minimal. Without these drugs, around a quarter of babies born to HIV-positive mothers would also contract the virus – and half of them would die before the age of two.”

Leopold Aschenbrenner and Daniel Kokotajlo have both argued that China must not reach AGI first. Have either of them given any update on how they think about US labs reaching AGI while Trump is in the White House?

Something pretty strange about where we are with LLMs is how bad the spam in my email inbox still is. I would have guessed we would routinely see super convincing, personalized spam by now.

The way the other nations exports are calculated in Trumps "tariff" chart is so incredibly dumb

I find many non-fiction books are more verbose than I would like. I'd often prefer a distilled version with a page count of roughly a quarter. I'd be willing to pay more for the distilled version than the verbose one. Could this be a new revenue stream for writers in the age of AI?

"Any grants, contracts, or collaborations involving mRNA vaccines be reported up the chain to Health and Human Services Secretary Robert F. Kennedy Jr.’s office and the White House" - Lysenkoism at work in the new NIH.

Most OECD countries fail to allocate even 0.15% of their national income to aid the world’s poorest countries, despite a commitment to do so. That's just $1 out of every $700. Only Luxembourg, Sweden, and Norway meet this minimal UN target. New cuts will deepen this shortfall.

My latest article on Our World in Data, looking at foreign aid and the difference we can make with personal donations: ourworldindata.org/foreign-aid-...

South Korea’s under-15 population has halved in two generations. I knew the population was aging quickly, and it’s no surprise that means fewer children—but the absolute numbers are striking. It's easy to look at fertility rates and forget about absolute numbers. That's a lot fewer kids around.

I think this is right. There is another interesting dynamic that for AI labs it would be very useful if academic research were freely available and so you have a powerful new force against established, paywalled scientific publishing.

OpenAI plus users now have access to the "Deep Research" feature. I just tried it for the first time and asked it for a report on a niche programming topic (comparing computation expressions in F# vs Algebraic Effects in OCaml) and the result was better than any blog post I know of on the topic.

This is quite surprising!

How could @ourworldindata.org maps be better? Do you experience any annoyances or pain points when you interact with our maps? Is there something you wish you could do that you currently can’t? What’s the next cool thing we could build on top of our maps? Any notes welcome! Thank you 🙏

StopTB has a new report estimating the impact of the foreign aid freeze. It's useful to understand the huge impact that global health efforts have everyday, and worrying. Some highlights... 🧵

AMFAR has published a report on how the foreign aid freeze affects PEPFAR, which actually still hasn't resumed. They estimate that hundreds of thousands of people lose access to HIV antivirals and 1500 babies are expected to contract HIV — *each day* 🧵

Since the start of the Syrian civil war in 2011, nearly half of all people born in the country emigrated. Most of these emigrants stayed close to home. Two-thirds now live in Turkey, Lebanon, or Saudi Arabia

Simon is one of the best voices on AI on the internet and his predictions in this post seem very reasonable. I particularly share his scepticism that general purpose AI Agents will work well soon. Interesting times ahead in any case!

Official data released today shows US data center construction hitting a new all-time high of $31.5B annualized, up 43% from this time last year and 128% since the release of ChatGPT two years ago

Nathan wrote a great post about what we know so far about o3, the recently announced new LLM by OpenAI

Amazing analysis! A fast rollout of malaria vaccines would be incredible - let’s do this!

If you are using obsidian then do yourself a favour and add the web clipper extension to your browser. It makes getting content from the web into obsidian much nicer and has replaced bookmarks for many use-cases for me. Inline LLM support is a great new addition but it’s really good without as well.

The world is awful. The world is much better. The world can be much better. All three statements are true at the same time. Understanding this is key to solving big global problems. We believe data & research can help us understand both the problems we face & the progress that’s possible. 🧵

Good opportunity to point out a nice OWID feature: interactive charts have dynamic social media preview cards.

If you adjust the chart parameters (add countries, change timeframe, etc.), the URL updates automatically. Share the link, and the social card shows exactly the view you customized ✨

The vast majority of people in the world — over 96% — live in the country where they were born. Only a small minority are international migrants. Insight for @ourworldindata.org ourworldindata.org/data-insight...
