I can’t stress enough how little an idea matters compared to the agency of the people executing the idea. I have had the privilege of knowing and sometimes even working with some of the most successful people (by various metrics). The difference between mediocre and excellent work and outcomes is predominantly one of agency. In practice this means: they dont wait for things to happen to them they go out and make things happen for them. They don’t wait for someone else to do something, for someone to teach them, for someone to give them the path, etc. They just go out and find a way to do it. I think the single biggest superpower these people have is the realization/belief that the world around them is completely mutable. Most everything that happens is because a person made it happen. I used to tell people to look around the room you’re sitting in. Look at everything. Every noun. It almost all exists because a person willed it into existence. Nothing is stopping you from doing the same. I see people online all the time dismissing someone else’s success because “I had that idea first” or whatever. I mean… yeah? If so then the difference is… you. So a bit of a self own whenever I hear that. Number one tip: act with agency.

Les graphistes qui se plaignent de l'IA, faut leur rappeler d'où vient leur métier. Pour sortir une affiche il y a 40 ans il fallait un maquettiste, un dessinateur-lettreur, un typographe, un correcteur, un photograveur, un chromiste, un monteur film, un copiste pour les plaques, un conducteur offset, un margeur. Dix mecs, des semaines, un atelier entier pour une affiche. Aujourd'hui c'est un type avec un MacBook et Photoshop. Deux heures dans son salon. Il a bouffé dix métiers tout seul et je n'ai jamais vu personne écrire une tribune sur la mort du chromiste. Le graphiste d'aujourd'hui n'est pas un artisan face à la machine. Il est déjà la machine. Chacun de ses outils est le fossile d'un métier qui a disparu pour qu'il puisse bosser seul. Donc venir dire que l'IA c'est le mal quand ton métier est né exactement de la même vague, c'est pas de l'éthique. C'est juste que cette fois c'est ton tour.
POV : tu es graphiste et tu te balades en vacances

Imagine the levels of propaganda it took to make you more comfortable with random beheadings and gang rapes than being called racist.

Narrative violations abound: - Demand for software engineers is rising - Software devs are rising as a share of new jobs - AI exposed industries are seeing above-trend wage growth - Open PM jobs haven't been higher since 2022 More from a16z's David George on the "AI job apocalypse" myth: a16z.news/p/the-ai-job-apoca…

Also don’t remember. But it’s been living rent free in my head ever since. Puts a very important truth that you intuit when building companies in a very accessible form.
I don't remember where I found this, but its spot on.

It’s 2026. You watch patiently as your delivery robot swerves to avoid the human body splayed out on the dirty, sunlight-dappled sidewalk to deliver the pizza you agreed to pay for in four installments with a $3 delivery fee + $4.99 service fee at 35.68% APR on Klarna.
Nothing right about this reality

How does a former empire recover from its collapse? It doesn't. Look at Spain 🇪🇸. Spain simply sat down on a bench for a quick siesta at 2:30 PM in 1650, drifted into a 3-century coma, & woke up to discover it was now a budget hotel for the British working class. The fall of the Spanish Empire is the most spectacular geopolitical nose-dive in human history. They went from being the terrifying "Sword of Christendom"—the nation that owned the Americas, the oceans, the Vatican, Austria, Germany, and Belgium—to being a country whose primary contribution to the modern world is "Ibiza", Zara, and tapas. Ok, I'm exaggerating a bit... But you get the picture. The tragedy of Spain isn't that they lost their empire; it’s that they became the servants of the people they used to bully. For two hundred years, the Spanish Infantry was the scourge of Europe, a terrifying machine of war that crushed Protestants for sport. Today? The descendants of those hardened tercios are frantically inflating banana boats for drunk German tourists in Mallorca. Spain possessed the greatest windfall in economic history: they looted an entire continent of its gold and silver. And what did they do with it? Did they build industry? Did they invest in infrastructure? No. They spent it all on fancy churches and wars they lost, then defaulted on their national debt thirteen times. They are the lottery winners of history who blew it all on cocaine and porcelain figurines and are now living in a trailer. Spain proves that you can be given the keys to the world and still manage to lock yourself out of the house.

AI OVERPRODUCTION China seeks to commoditize their complements. So, over the following months, I expect a complete blitz of Chinese open-source AI models for everything from computer vision to robotics to image generation. Why? I’m just inferring this from public statements, but their apparent goal is to take the profit out of AI software since they make money on AI-enabled hardware. Basically, they want to do to US tech (the last stronghold) what they already did to US manufacturing. Namely: copy it, optimize it, scale it, then wreck the Western original with low prices. I don’t know if they’ll succeed. But here’s the logic: (1) First, China noticed that DeepSeek’s release temporarily knocked ~$1T off US tech market caps. (2) Second, China’s core competency is exporting physical widgets, more than it is software. (3) Third, China’s other core competency is exporting things at such massive scale that all foreign producers are bankrupted and they win the market. See what they’re doing to German and Japanese cars, for example. (4) Fourth, China is well aware that it lacks global prestige as it’s historically been a copycat. With DeepSeek, becoming #1 in AI is now something they actually consider possibly achievable, and a matter of national pride. (5) Fifth, DeepSeek has gone viral in China and its open source nature means that everyone can rapidly integrate it, down to the level of local officials and obscure companies. And they are doing so, and posting the results for praise on WeChat. (6) Finally, while DeepSeek was obscure before recent events, it’s now a household name, and the founder (Liang Wengfeng) has met both with Xi but also the #2 in China, Li Qiang. They likely have unlimited resources now. So, if you put all that together, China thinks it has an opportunity to hit US tech companies, boost its prestige, help its internal economy, and take the margins out of AI software globally (at least at the model level). They will instead make their money by selling inexpensive AI-enabled hardware of increasing quality, from smart homes and self-driving cars to consumer drones and robot dogs. Basically, China is trying to do to AI what they always do: study, copy, optimize, and then bankrupt everyone with low prices and enormous scale. I don’t know if they’ll succeed at the app layer. But it could be hard for closed-source AI model developers to recoup the high fixed costs associated with training state-of-the-art models when great open source models are available. Last, I agree it’s surprising that the country of the Great Firewall is suddenly the country of open source AI. But it is consistent in a different way, which is that China is just focused on doing whatever it takes to win — even to the point of copying partially-abandoned Western values like open source, which seemed like the hardest thing to adopt. On that point: they did build censorship into the released DeepSeek AI models, but in a manner that’s easily circumvented outside China. So, you might conclude they don’t really care what non-Chinese people are saying outside China in other languages, so long as this doesn’t “interfere with China’s internal affairs.” Anyway —this is an area I’ve been watching, and my reluctant conclusion is that China is getting better at software faster than the West is getting better at hardware.
What's the best explanation you've heard for why China is leaning so hard into open source? It's now an official position from the foreign ministry apparently.

An exciting milestone for AI in science: Our C2S-Scale 27B foundation model, built with @Yale and based on Gemma, generated a novel hypothesis about cancer cellular behavior, which scientists experimentally validated in living cells.  With more preclinical and clinical tests, this discovery may reveal a promising new pathway for developing therapies to fight cancer.

quick thoughts on things we may see in 2025… (1) A new wave of investigative journalists will break news via betting markets. We learned in the election that betting markets are, in most cases, more accurate than professional polling and news reports of voting trends. While there seems to be no disincentive for spreading false information these days on social media, people act differently when money is on the line. The general population may benefit from bottom-line-driven fact checking and the use of betting markets to suss out the truth of what is really happening. I think we’ll see new types of tech-enabled betting markets AND a new cohort of investigative journalists and researchers become wealthy news sleuths by sourcing proprietary insights and breaking the news via betting markets as opposed to mainstream news outlets that are funded via advertising/clicks.

It's fascinating that one of the best libraries for implementing user authentication, Lucia, in the latest "release", turned out to be a guide on how to implement authentication from scratch. As the author (Pilcrow) explains, it's better to write it from scratch, which is not that hard, and use the guide as a reference. This way, you can build a highly customizable authentication that fits perfectly into your app. I'm building a dashboard with auth for @LocalCanApp, and I'm doing just that. It's a bit of a steep learning curve, but I'm absorbing a lot of knowledge and I'm sure understanding fundamentals like auth will pay dividends in the future. Plus, it's super interesting.
