Noah Smith on what it means when AI becomes better at mathematics than any human—how “hero” mathematicians shaped culture, and how post-heroic math and science might look when machines own the frontier.

There's no point at which turning your brain off will work
Dan Luu argues that turning off critical judgment while using LLMs fails in practice: when people let models take actions or produce analyses without verification, errors compound — there is no safe point at which you can stop thinking.

Deterministic Core, Non-Deterministic Shell
Fourteen years after Functional Core, Imperative Shell, Outdata argues for a deterministic core with a non-deterministic shell—keeping pure logic testable while isolating AI and I/O uncertainty.

You're Leaving Compute on the Table
Nishant Joshi tallies roughly 15 TFLOPS of idle GPU and neural compute sitting on his desk across a MacBook, Mac mini, iPhone, and AirPods, and argues product teams should push more work onto users' own devices while keeping identity, billing, and source of truth on the server.

AI and Math in 2026: a non-mathematician's read
xlr8harder synthesizes recent AI math results for non-specialists: real progress with a different strength profile than humans, formalization cliffs, and why “math nearly conquered” remains overhyped.

The UV index is not the warm sensation of sunlight on bare skinWhy sunburn risk and how hot the sun feels on your skin diverge—backed by numbers.
A clear, numbers-first essay explaining why the warmth of sunlight is a poor proxy for UV-B sunburn risk: cloudy cool days can still burn, and scorching morning heat may not, once you separate infrared heating from the UV index.

Land Value Capture in Practice: Reflections on Ethiopia's Urban Land Lease System
Wudu Muluneh Yimer, a former Addis Ababa district municipal manager who ran land tenders in Bole Sub-City, traces three decades of Ethiopia's urban land lease system, where all urban land is publicly owned and leased rather than sold, weighing its power to capture land value for infrastructure against weak institutions, valuation and enforcement.

Reflections on 1,000 Days of Math
I finally hit 1,000 days of doing math daily! Early on in my journey I was a lot more aggressive with my XP targets, but settled into a low-volume rhythm as my goals evolved. I worked from MF1 (Math Foundations 1, lowest level) into MF3, then about halfway through MF3 I started M4ML (Mathematics for Machine Learning). ### Self-induced friction But it got really hard and my progress started to slow as lessons took longer, which was problematic because I was trying to limit my math time to <20m/day. That may have worked fine, but I really screwed myself by relying on…

Lotus Notes and the dangers of starting from scratchYou either loved it, or were using it wrong.
Matthew Guay traces how Lotus Notes — which launched in 1989 with encryption, rich text, file attachments, and a synced database before any of those features existed in standard email — was eventually defeated not by being worse than competitors but by being too unfamiliar. The essay is a history of a product so far ahead of its time that its interface became its downfall.

"Vibe coding" is the new "Internet dating"
An analogy between early-2000s internet dating stigma and today's vibe-coding skepticism: both start as jokes, then quietly become how a lot of people actually meet their goals.

Put a price on research breakthroughs
Alex Wang argues that AI neolabs are being asked to pull off two moonshots at once, a research breakthrough and a venture-scale business, and proposes a pharma-style model where frontier labs put explicit prices on breakthroughs such as cheaper training runs so neolabs can focus on research and sell or be acquired.
