Evaluating the impact of two decades of USAID interventions and projecting the effects of defunding on mortality up to 2030: a retrospective impact evaluation and forecasting analysis USAID funding has significantly contributed to the reduction in adult and child mortality across low-income and middle-income countries over the past two decades. Our estimates show that, unless the a...

Forecasts suggest current steep funding cuts to USAID funding could lead to over 14 million extra deaths (range: 8.5–20 million) by 2030 - including 4.5 million children under 5 (3.1–5.9 million).

Childhood leukemia used to be a death sentence for the vast majority of patients. Now, most children in rich countries are cured.

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.

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

β€œβ€¦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?

Yeah that is an interesting theory - but then I’m still surprised that there isn’t more experimentation in that space. Not that I mind of course, I just find it a bit counterintuitive.

Maybe but LLMs are pretty cheap nowadays and most spam is really terrible. I’d guess that even just using a cheap, small model could improve the rate of replies a ton.

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.

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?

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.

For many of us, it doesn’t cost much to improve someone’s life, and we can do much more of it Most countries spend less than 1% of their national income on foreign aid; even small increases could make a big difference.

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 childrenβ€”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.

GDP per capita This data is adjusted for inflation and for differences in living costs between countries.

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 πŸ™
