SaaStr: “Here’s the counterintuitive insight that’s reshaping how the smartest AI founders think about unit economics: Your inference costs aren’t your gross margin problem. They’re your CAC replacement. If … You Have a Product That Can Truly Deliver with AI. The companies growing fastest right now—Cursor crossing $1B ARR with ~300 employees and no traditional marketing, Lovable and Replit both hitting ~$300M ARR with zero paid acquisition, Harvey and Legora in legal, OpenEvidence in healthcare—aren’t sweating inference costs. They’re optimizing them for sure, but they are also leaning into them. They’re treating compute as their primary growth investment, not their primary margin drag.”
Andrej Karpathy: “It is hard to communicate how much programming has changed due to AI in the last 2 months: not gradually and over time in the “progress as usual” way, but specifically this last December. There are a number of asterisks but imo coding agents basically didn’t work before December and basically work since – the models have significantly higher quality, long-term coherence and tenacity and they can power through large and long tasks, well past enough that it is extremely disruptive to the default programming workflow.”
FT: “The internet made information global. Crypto is making a similar impact on money. While recent headlines might fixate on prices of bitcoin, a deeper and longer-lasting shift is under way in digital payments. This is the year that stablecoins, or cryptocurrencies pegged to assets such as the dollar, are becoming part of the mainstream for online and international payments. Call it money’s “WhatsApp moment”. Just as chat apps like WhatsApp collapsed the cost of international messaging from, say, 30 cents per text to zero, stablecoins are doing the same in financial transactions. The numbers bear this out: stablecoins moved over $12tn in value last year, after filtering out bots and other inorganic activity — volumes that are rising towards Visa’s $17tn of transactions last year but made at a fraction of the cost. In the process, stablecoins are bringing the internet’s original vision of openness and interoperability to finance. Given how blockchain technology allows stablecoins to be programmed, money is in effect becoming software.”
WSJ: “In past eras, the perfect weapon was one that would inflict maximum damage on an enemy. A bigger cannon, a more explosive shell, a better strategic bomber—a B-52 instead of a B-29—or a hydrogen bomb instead of an atomic one. In “The Warhead” Jeffrey Stern…traces the evolution of precision-guided munitions (PGMs) over the past half-century. By Mr. Stern’s account, the PGM represents a technological breakthrough that has changed history and the way wars are fought. It’s an absorbing tale of scientific and technological achievement, political and military hubris, and the story of ordinary people being caught up in other people’s bad decisions—and dying as a result.”
