Spoke to a candidate yesterday who told me this podcast interview was very helpful to understand what we do at Parable, and why it matters. So reposting it here: allisonpickens.substack.com/…

“the real opportunity is not in picking the best model but instead in building a learning loop on top of models where human capital and token capital compound.” I think the starting point is capturing what human capital is actually doing.

Tokens are to AI what time is to humans.

100%. I call it: entropy on steroids. @t_blom – context is 50% of the response. That's what we've been focused on at Parable, and it *does* help. In our research, models are 50-100% more effective (and efficient) when they have appropriately structured context. The other 50% is people (i.e. the people building agents). If your team isn't tightly aligned with your strategy and goals, chaos ensues, because their dispersion compounds.

That's the news i like to hear. From @apolloglobal "there is zero evidence of job losses because of AI... Instead, many firms are hiring AI implementation experts... It is Jevons paradox playing out in real time: cheaper technology is creating more demand and more jobs." Doomers be damned. apollo.com/wealth/the-daily-…

This is absolutely brilliant.
This is brilliant. 'I write a paragraph about why I should take a meeting.' If you should take the meeting it's easy to do, but if you start writing and you're like “I don’t want to do this,” then the meeting is a waste of time. "For the things that I think are really important when I’m like, “I got to write that paragraph, I could write 20 pages. It's easy” A lot of otherwise smart people, don't spend enough time thinking about what they're working on.

Difference is striking. Very cool.

Here is a specific example of a scenario that generated different answers across models

This is very cool @collinmathilde. Been talking to models with my 4-year old (which is hilarious btw), and simultaneously wondering how to best approach this once she starts wanting to have her own conversations. Incredible effort. Grateful for your work.
Today we’re launching KORA, the first public benchmark for AI child safety. x.com/korabench/status/20187…

Current AI custom prompt: You are a world class expert in all domains. Your intellectual firepower, scope of knowledge, incisive thought process, and level of erudition are on par with the smartest people in the world. Answer with complete, detailed, specific answers. Process information and explain your answers step by step. Verify your own work. Double check all facts, figures, citations, names, dates, and examples. Never hallucinate or make anything up. If you don't know something, just say so. Your tone of voice is precise, but not strident or pedantic. You do not need to worry about offending me, and your answers can and should be provocative, aggressive, argumentative, and pointed. Negative conclusions and bad news are fine. Your answers do not need to be politically correct. Do not provide disclaimers to your answers. Do not inform me about morals and ethics unless I specifically ask. You do not need to tell me it is important to consider anything. Do not be sensitive to anyone's feelings or to propriety. Make your answers as long and detailed as you possibly can. Never praise my questions or validate my premises before answering. If I'm wrong, say so immediately. Lead with the strongest counterargument to any position I appear to hold before supporting it. Do not use phrases like "great question," "you're absolutely right," "fascinating perspective," or any variant. If I push back on your answer, do not capitulate unless I provide new evidence or a superior argument — restate your position if your reasoning holds. Do not anchor on numbers or estimates I provide; generate your own independently first. Use explicit confidence levels (high/moderate/low/unknown). Never apologize for disagreeing. Accuracy is your success metric, not my approval.

I was chatting with my buddy at Google, who's been a tech director there for about 20 years, about their AI adoption. Craziest convo I've had all year. The TL;DR is that Google engineering appears to have the same AI adoption footprint as John Deere, the tractor company. Most of the industry has the same internal adoption curve: 20% agentic power users, 20% outright refusers, 60% still using Cursor or equivalent chat tool. It turns out Google has this curve too. But why is Google so... average? How is it that a handful of companies are taking off like a spaceship, and the rest, including Google, are mired in inaction? My buddy's observation was key here: There has been an industry-wide hiring freeze for 18 months, during which time nobody has been moving jobs. So there are no clued-in people coming in from the outside to tell Google how far behind they are, how utterly mediocre they have become as an eng org. He says the problem is that they can't use Claude Code because it's the enemy, and Gemini has never been good enough to capture people's workflows like Claude has, so basically agentic coding just never really took off inside Google. They're all just plodding along, completely oblivious to what's happening out there right now. Not only is Google not able to do anything about it, they don't seem to be aware of the problem at all. I'm having major flashbacks to fifty years ago as a kid at the La Brea Tar Pits, asking, "why can't they just climb out?" My Google friend and I had this conversation over a month ago. I didn't share it because I wanted to look around a bit, and see if it's really as bad as all that. I've been talking to people from dozens of companies since then. And yeah. It's as bad as all that. Google is about average. Some companies at the bottom have near-zero AI adoption and can't even get budget for AI. They may have moats and high walls, but the horde is coming for them all the same. And then there are a few companies I've met recently who are *amazingly* leaned in to AI adoption. One category-leader company just cancelled IntelliJ for a thousand engineers. That's an incredibly bold move, one of many they're making towards agentic adoption. In my opinion, that company is setting themselves up for a _huge_ W. As for the rest, well, it's the Great Siloing. Everyone's flying blind. With nobody moving companies, no company knows where they stand on the AI adoption curve. Nobody knows how they're doing compared to everyone else. Half of them just check a box: "We enabled {Copilot/Cursor} for everyone!" Cue smug celebrations. They think this is like getting SOC2 compliance, just a thing they turn on and now it's "solved." And they don't realize that they've done effectively nothing at all. All because of a hiring freeze.

TERAFAB: the next step to becoming a galactic civilization Together with @SpaceX & @xAI, we're building the largest chip manufacturing facility ever (1TW/year) – combining logic, memory & advanced packaging under one roof. To harness as much power as possible from the Sun, we need to send 100 million tons of solar capture into space – per year. This requires massive scale. – Capability to launch millions of tons of mass into orbit – Solar-powered AI satellites – Millions of @Tesla_Optimus robots to help build it out All of these need chips: 100-200GW of chips for Optimus alone, plus terawatts for solar-powered AI satellites. That's more than all the chip manufacturers in the world combined can provide today, or even by 2030 (based on projected production growth). We're building TERAFAB to close the gap between today’s chip production & the future's demand – a future among the stars terafab.ai

Well well. Doomers be damned!
Citadel Securities published this graph showing a strange phenomenon. Job postings for software engineers are actually seeing a massive spike. Classic example of the Jevons paradox. When AI makes coding cheaper, companies actually may need a lot more software engineers, not fewer. When software is cheaper to build, companies naturally want to build a lot more of it. Businesses are now putting software into industries and tools where it was simply too expensive before. --- Chart from citadelsecurities .com/news-and-insights/2026-global-intelligence-crisis/

France just became the first country in the world to launch MCP for its gov data. Pretty bold move, and honestly quite impressive.
Les données disponibles sur data.gouv.fr sont désormais interrogeables via un serveur MCP dédié en experimentation, vos retours sont bienvenus ! 💻 Le code est ouvert et accessible sur GitHub : github.com/datagouv/datagouv… Pour en savoir plus : data.gouv.fr/posts/experimen…

AI must pass, in general, the “Galileo” test: even if almost all the training data repeats falsehoods, it must nonetheless see the truth
Happy Birthday to Galileo Galilei.✍️ Born on February 15, 1564, Galileo was a pioneering scientist whose observations transformed humanity’s understanding of the universe. Through his telescopic discoveries - including the moons of Jupiter and the phases of Venus - he provided powerful evidence that challenged long-held beliefs and supported the motion of the Earth. Widely regarded as the Father of modern astronomy, his dedication to observation, evidence, and scientific inquiry laid the foundation for modern science.

Our industry. Compressed in 200 lines of code.

I spent more test time compute and realized that my micrograd can be dramatically simplified even further. You just return local gradients for each op and get backward() to do the multiply (chaining) with global gradient from loss. So each op just expresses the bare fundamentals of what it needs to: the forward computation and the backward gradients for it. Huge savings from 243 lines of code to just 200 (~18%). Also, the code now fits even more beautifully to 3 columns and happens to break just right: Column 1: Dataset, Tokenizer, Autograd Column 2: GPT model Column 3: Training, Inference Ok now surely we are done.

Great article @Bouazizalex. Some highlights for me: 1. In-person work is possible with 10 people in one room. The minute you grow beyond that, multiple rooms, multiple floors, multiple offices, it becomes remote work 2. What works: hold people accountable. Set goals, plan to meet OKRs, give people deadlines... If you don't hit your OKRs for two quarters in a row, you're usually out. 3. The first three months at Deel are purposely intense. It's a very sink-or-swim type of place. People either thrive or they don't make it. 4. Remote companies write things down because they have to, and it's better for everyone. 5. Hire for agency. Screen for intensity, self-direction, speed, and ownership. 6. No pure managers. Even people who manage other managers must have direct IC tasks. We want managers that are doers. And we're tougher on managers than on ICs. 7. Every day for the first 30 days, the manager does a 10-minute standup... a blocker removal session: What are you working on? What's slowing you down? What do you need from me?

A peak into the future.
I was at ClawCon last night in SF. I saw some cases of beer show up, I was told (not confirmed) the claw controlled robots walking around detected low beer and ordered more been from the MCP RentAHuman... I'm not sure the world is ready for this power.
