Why did @JeffDean leave Google after 27 years? Here's the answer in his own words! “Sometimes being a focused small company, with everyone focused on exactly that mission… can be amazing,” he said this at the AASF 2026 conference at Stanford. Jeff had watched Google grow from 25 people to more than 190,000. Now, with his new venture @DiscoLoopAI, he is returning to something much smaller: a focused group of people united around one ambitious mission—to use AI to accelerate scientific and engineering discovery. Perhaps he is just searching for the feeling of early Google again: a small team, a huge vision, and brilliant people all pulling in the same direction. Large companies have resources, but small teams have dreams and focus. Best of luck, Jeff! You'll always have our support! 😊

Wow. Incredible entrepreneur @howietl and the entire Airtable team building another cool product used by so many companies. And sobering reality check on 2021 peak VC valuations. Congrats Howie!

Can you outsource taste? This is such a thought-provoking question by @reidhoffman. Artist Joe Salvatore said it well: “I can outsource production, but I can't outsource my taste."

Reuters reports that the Trump administration is preparing to block imports of new Chinese humanoid robots, robot dogs and certain power inverters. There is also a claim circulating on X that Chinese AI models will be banned today. But so far, I have not seen that confirmed in the Reuters report or by an official announcement. So I would treat that part as speculation for now. I get the security concern. A robot is no longer just a machine that moves. It has cameras, microphones, sensors and internet access. It could be operating inside a factory, laboratory, warehouse or even someone’s home. Power inverters are even less glamorous, but possibly more sensitive. They connect solar panels, batteries and other equipment to the electricity grid. If they can be remotely accessed or controlled, they become part of the national-security conversation. But here is the question I keep coming back to: How does America plan to build a competitive robotics industry without relying on China’s robotics supply chain? China installed 295,000 industrial robots in 2024—more than half of all the industrial robots installed worldwide that year. Four of the five largest humanoid-robot companies by 2025 installations were Chinese. China also has major advantages in many of the components robots need: permanent magnets, motors, batteries, bearings, power electronics and increasingly actuators and sensors. This does not mean every robot component is made in China. Japan, Germany, South Korea and other countries remain important suppliers. But China has something that is very difficult to reproduce: the factories, suppliers, engineers, component makers and customers are all close to one another. A robot company can design something, find parts, build a prototype, test it and move toward production much faster—and usually much more cheaply. So banning Chinese robots may solve one security problem, but it raises several others. Will American robotics companies still be allowed to buy Chinese components? Will the government invest enough to build alternative supply chains? Will these restrictions help American companies—or simply make robots more expensive and slow down adoption? And if the U.S. restricts Chinese robots while China continues deploying them across factories, warehouses and public services, who will collect more real-world data and improve faster? The U.S. may still have an advantage in the AI “brain.” China has a serious advantage in building the robotic “body.” You can ban a finished product quite quickly. Rebuilding the industrial ecosystem behind it is much harder.
