The man who is perpetually hesitating which of two things he will do first, will do neither. The man who resolves, but does not execute his resolution, has not yet learned to think.

The Monday Media Diet with Matt Spevack

I guess some might argue that reading would have the benefit of expanding my mind, but I already have so many creative and administrative projects I'm excited about that I can hardly keep up with my own ideas. That's my unapologetic justification for not reading.

A thought which does not result in an action is nothing much, and an action which does not proceed from a thought is nothing at all.

The case for making your own apps

"What started as a little tool suddenly becomes this glorious massive app that wants to do everything," he said — and "sometimes those apps get more in the way than they actually help."

A country is only as valuable as its eccentrics

The UK is the world's third-largest destination for private AI capex investment over 2013-25, behind only the US and China, according to Stanford's 2026 AI Index Report. Bank of America makes the argument that the takeover wave is a short-term facet of foreign direct investment that's shifting the UK economy in the longer term "towards higher productivity/capital intensity".

It is not by augmenting the capital of the country, but by rendering a greater part of that capital active and productive than would otherwise be so, that the most judicious operations of banking can increase the industry of the country.

The record of a man who makes consistently good decisions in complex situations is almost always a record of a man who has reduced the number of decisions he has to make. The more choices you face, the more your judgment degrades.

🎙️ How I AI: GPT-5.6 review, How a solo builder runs 24/7 local AI, and What an agent harness is and how to build one

The open chat field has been good enough, until it stopped being good enough. I acknowledge in this episode that just typing into Claude Code has produced real work. But this marks a shift in my thinking: general-purpose agents are now better used to orchestrate specialized harnesses than to do every job themselves. Giving a constrained agent a specific harness gets more consistent output than giving a powerful agent an open prompt.

Not the future. Don't talk about the future.

A company that replaces a billing department with a chatbot interface records lower costs and higher output per worker. The national accounts register a productivity gain. But the hours that patients spend decoding their own tests appear nowhere — not in labour statistics, not in GDP.

OpenAI's big launch — and bigger departure

My big takeaway is that both Sol & Fable represent jumps over previous models and have opened a large gap with the next-best AIs. People will have preferences for one or the other, but if you [are] doing any work where better intelligence matters, those two models are your only choices.

The Best Summary of Atlas Shrugged

The crisis was not caused by the producers. It was caused by a society that believed it could consume achievement while attacking the people who make achievement possible. Without the producers, the system that exploited them can no longer function, and society collapses.

The Token Apocalypse

The peak of 'tokenmaxxing', this suspicious trend in Silicon Valley where a workplace culture frenzy of burning through as many AI tokens as possible as a shorthand for productivity—ran into a major reality check sometime in the early spring of 2026 when they got the Claude bills. The adoption of Chinese open-weight models coincided with the reaction to that. This is actually a failure of AI agents and productivity if you read between the lines.

The funnel of opportunity is wider than most people think, but the filter of execution is far narrower than most people realize. Ideas are not the scarce resource; disciplined follow-through on a single idea, long past the point of comfort, is what almost no one can sustain.

The model doesn't actually remember previous conversations unless you use the Memory feature or paste in prior context yourself. Each new chat window starts completely fresh, which means if you want consistency across sessions, you have to build that context manually.

🎙️ How I AI: Claude Fable 5 review & How Braintrust uses AI agents, evals, and CI to ship better software

Practical quality beats theoretical quality every time. In theory, a human engineer with infinite time and focus might produce better code than an AI agent. In practice, humans lose context over days, have decaying attention spans on hard-but-tedious problems, and skip benchmarks they know they should run. AI agents maintain consistent focus, run every test, and can work on problems continuously for days or weeks.

Inside the companies pulling ahead — Anthropic, Cursor, Cognition, Replit, and a small number of others — a different unit shape had emerged: five-to-ten people, direct CEO reporting, broad decision rights, hybrid roles, communication overhead at roughly one-tenth of a comparably-staffed conventional product unit.

The reason is obvious when you think about it: enterprises are paying for their employees' time, so of course they are willing to pay for tools that make those employees more productive; consumers, on the other hand, are mostly looking to waste time, which is why attention-harvesting advertising is the only software business model that works at scale for consumer services.

How much more software do we really need?

For companies using advanced AI coding tools, only 18% of spending on tokens is translating into shipped coding products that reach real users, according to EntelligenceAI, a startup that aggregated data on more than 2,000 companies using advanced AI tools for coding. Jellyfish, a company that tracks AI usage, found rapidly diminishing returns in terms of converting tokens to actual software.
