The standard diagnosis runs roughly: too much capitalism, too much profit, too many private companies, too little government. The corollary is

How to Vibe Code as a Senior Engineer

Over the past few months, I’ve rediscovered my love for building software. Not in the traditional way—writing line after line of code, plumbing together brittle libraries, grinding through boilerplate. Instead, I’ve been vibe coding. Vibe coding is a new way of building software where

We Won’t Save the Planet by Shrinking

At first, it sounds obvious: if we want to save the planet, we should do less . Fewer people, less consumption, smaller footprints. I believed this too—so much so that I once thought having kids was irresponsible. But the more I looked into it, the less sense it made.

AGI, agents, and timelines

AGI is coming—whether we’re ready or not. I’ve been convinced of this trajectory since GPT-3’s release, but recent developments have significantly accelerated my timelines. The first major shift was OpenAI’s breakthrough in test-time compute and its newly demonstrated

Artificial Knowledge Creation

How does creativity work and is it possible to bottle it up inside a computer? This is what we know so far.

Unshackling Artificial Minds

Humans, by nature, seem to be drawn to pessimism. It's a tendency rooted deep within us, a product of Entropy, the law of nature that dictates it is easier to destroy than to create. And here we are, on the cusp of creating not just something new, but

Captain's Log #2

On projects, side-projects, AI, and existential dread.

The Stars

Technology's ability to improve lives and alleviate suffering is undeniable. It has swept through our lives like a tidal wave, lifting us from the depths of ignorance and suffering. It continues to reshape the world and grants us access to tools and knowledge previously unimaginable. Yet, there was

The Illusion of Free Will

One of the most difficult concepts to grasp is the idea that free will, the cornerstone of our human experience, might be nothing more than an illusion.

Universality and APIs

From Roman numerals to Indian digits, from hieroglyphics to Latin languages, universality has been the key to unlocking human progress.

Captain's Log #1

In this episode of Captain's Log we cover artificial intelligence, taste companies, mom & pop tech businesses, and more.

The AI is coming

May you live in interesting times, goes the ancient Chinese proverb. Recent developments in artificial-intelligence, especially image-generation, are putting that curse to the test. In the last year we’ve seen some incredible breakthroughs in image-generation with the release of new algorithms: Dalle 2, Midjourney, and
