TLDR 2026-11-13

Companies are waking up to the reality that AI is expensive. But limiting every engineer to $20, $50, or $100/month holds back your best builders and costs you in delayed delivery.

What's the better approach? This report by Cognition provides a framework for setting token limits by efficiency, not blanket rules. Explore:

• Grading each engineer on productive hours per unit of spend
• How automatic cap increases (up to 22x!) helped on engineer increase merged PRs from 30 to ~80/week
• Using Devin Coach to flag vague prompts, expensive modes, and mixed-up sessions before they run

SpaceX and Tesla could announce a merger deal as soon as December. The companies' boards and advisers are working out the terms of the deal and the governance structure of the combined entity. The merger will be a major test case for political sentiment following the US midterm elections. The aggressive timeline reflects Elon Musk's tendency to move quickly when it comes to corporate maneuvers.

Jensen Huang has resigned as Nvidia's CEO after the revelation of two extramarital affairs. Finance chief Colette Kress will serve as interim CEO until a permanent successor is named. The board is considering both internal and external candidates. Nvidia's board has appointed long-time director Harvey C. Jones as its first ever chair. Huang has previously said that he doesn't believe in succession planning and that leaders should continuously pass on knowledge and information as they have it.

mRNA technology has the potential to generate hundreds of new treatments for a range of diseases. It is quickly becoming the preferred technology for its speed - a vaccine can be created against any pathogen within six to eight weeks, less time than it takes to conduct the studies required to establish a therapy's safety and efficacy. The technology could redesign treatments in infectious diseases, rare diseases, and cancer.

Chinese drugmakers account for at least a third of the world's pipeline of innovative drugs in development, but China-originated novel treatments have yet to reach overseas markets at scale. The country runs more clinical trials than any place else. Chinese drugmakers with global ambitions currently pursue them primarily through partnerships with Western companies, who usually take charge of late-stage development and eventual sales of the drugs outside of China. Some lawmakers in the US are calling for restrictions on partnerships with Chinese companies, but industry analysts say the business momentum is too strong to break.

Intel asked 800 senior business, IT and robotics leaders which robots will matter most in their industry over the next five years. Humanoids got 6% of the votes. 77% said reliability matters more than what a robot looks like. See the full breakdown in Intel's Robotics Readiness Gap report.

AI is writing significantly less slop, but slop has not been eliminated. Slop has now moved up the stack to infest design decisions. Frontier agents lack foresight into how their code will be used. They display poor abstraction design and complete disregard for reusing library-provided code.

You develop a lot of intuition throughout your career through experience. This knowledge and experience is what makes leaders effective. However, once in a while, it's worth revisiting ideas that were once considered bad. Some of the intuition you're relying on might not be worth as much anymore, as things change.

Safety-conscious employees at AI companies should unionize, as this would give them the power to keep their employers in check if they have concerns about their work. There are so few skilled AI researchers that companies will want to negotiate if a dozen top AI researchers threaten to walk. A union would uphold normal protections around discipline and firing, demand transparency, and act as an independent voice to hold companies to their commitments. RSI could make AI employees obsolete as soon as next year, so they need to take action now, as they may never have this amount of leverage again.

Google has partnered with Samsung, Gentle Monster, and Warby Parker to create Gemini-powered smartglasses. The frames, which all weigh around 41 grams, will have a camera that Gemini can use for tasks. The assistant will have access to user data and preferences to produce personalized answers. Google claims it has implemented a number of features and limitations to ensure that people don't do creepy things with the device, and that it doesn't do creepy things to users.

Robot demos are everywhere, but few robots work every shift. Intel shares 40+ years of production lessons on battery life, heat, real-time control, site adaptation, and running fleets for years.Read more here.

Rust 1.100.0 stable features the never type, the Allocator and DropGuard APIs, conjuring zero types, and more.

Tim Cook has an unparalleled track record of succeeding a bigger-than-life founder.

China will have 10 times the electricity of the US in 10 years if trends continue.

Younger people may not care too much whether AI will be able to prolong life, but older people have shorter timelines, so they are more incentivized to accelerate development.

Microsoft has determined that the problem is being caused by servers unexpectedly becoming unavailable.
