Nice post! Two quick reactions reactions as a Brazilian working on AI impacts for the past ~3 years now:
The debate in Brazil seems yoo unfocused -- too ambitious and not ambitious enough at the same time. I get overwhelmed every time I try to catch up, and this leaves me paralyzed when I consider contributing occasionally somehow to "build in parallel" initiatives unless there are very specific asks. An EU-AI-Act-style regulation, an AI strategy, all the misinformation discussion that intermingles with AI, social-media-regulation discussions that also intermingle with this, etc. I think this unfocusedness is downstream of a lack of clarity about what the Brazilian government's [or the Brazilian state's] goals with AI are. And this seems to contaminate the discussions I see among EA-aligned Brazilians working on AI governance.
"trillions of capital are being flooded into accelerating AI development across industries" fwiw this seems only correct under a very expansive definition of accelerating AI development, e.g. all hyperscaler capex (including non-AI spend and AI inference) was ~$500 billion in 2025
"while a measly $50 million dollars" this seems outdated -- Coefficient Giving’s Technical AI Safety team made 140 million USD in grants in 2025. If you consider all other funding (the UK AISI's founding budget was ~$125M, internal lab speding on technical AI safety, other grantmakers, etc.), it's plausible we're over $1 billion.
Some notes on OpenAI disproving the Erdős unit distance conjecture (from a non-mathematician):
My sense is that you're right. IIRC diminishing returns are more salient for AMF than for GiveDirectly, and one of the key arguments pro GiveDirectly would be that flat returns persist longer -- but probably when they make this argument they're thinking on the scale of $100M–$1B, not hundreds of billions.
Perhaps the best case in point would be Bolsa Família: ~$30B yearly budget, one of the largest conditional cash transfer programs in the world, increased ~5-fold over the past few years, noticeably turned into a less effective program imho, but still seems like one of the most effective programs from the Brazilian government
I wouldn't think of this as a matter of thresholds but continuously decreasing returns, tho
Lighting has been getting ridiculously cheaper. And for the most part we seem to be not taking advantage of that positive externality: reducing crime through better lighting. This has been battle-tested as one of the effective ways for public security, see Chalfin, Hansen, Lerner & Parker (2022), an RCT in NYC public housing finding ~36% reductions in nighttime outdoor index crimes from added street lighting. Many, many major cities still haven't copied this at the right levels!
But we're also getting substantially negative externalities of bright lighting. Office buildings that never turn off their lights because why would they care. Apropos the new office building that just opened next to my housing. This may alimentate NIMBY spirits in me, God forbid. Kyba et al. (2017) document that Earth's artificially lit outdoor area grew 2.2% per year from 2012 to 2016, with the LED transition producing a rebound effect instead of getting savings. Jevons paradox and such.
Also, this has all sorts of annoyances. I think malls, pharmacies, and hospitals have all become much brighter since my childhood. I may be more sensorially overloaded than most people, but this does meaningfully affect my qualia, so much that Pigou himself would collect taxes from the pharmacies with dozens and dozens of LEDs, while Coase would advocate that I have the natural property right of not being assaulted with that much lumen while buying a Tylenol. This does affect wellbeing of more than just me (Cho et al. 2015). But lightly enough, ha, to not be a topic of discussion.
I'm not sure how similar or dissimilar the Taiwan case is, but in Brazil I've seen people discussing (and acting) on strategies like this, and in almost every case going to top-tier Brazilian schools with better launchpads (e.g. professors having stronger connections abroad; more like-minded peers; exchange programs) seems to have paid off better than going to mid-tier schools, even when accounting for the much more rigid grading at the top-tier ones or that's harder to get a top-tier class rank, or for how much harder it is to achieve a top class rank there
