I REPLACED A $120/YEAR MICRO-SAAS IN 20 MINUTES WITH LLM-GENERATED CODE

It's now possible to replace services with AI-generated code, if you know what you're doing. It's only going to get easier. SaaS businesses that don't give ongoing value are at risk of being replaced by customers. The ease of developing these tools will mean that buying and selling SaaS businesses will become less profitable.

TESLA IS COMMITTING AUTOMOTIVE SUICIDE

Tesla's Q4 2025 earnings call made it clear that the company is no longer interested in being an automaker. The company has killed the Model S and Model X and has no plans for new mass-market models. It is pivoting entirely to 'transportation as a service'. Tesla will continue to focus on robotaxis, humanoid robots, and their supporting infrastructure, especially training compute.

ANDROID'S FULL DESKTOP INTERFACE LEAKS

A bug report on the Chromium Issue Tracker has inadvertently leaked the Android desktop interface. The bug report, which was about Chrome Incognito tabs, was accompanied by two screen captures. They show a taller status bar compared to tablets, a Chrome interface that mostly aligns with the current large-screen Android version, and mostly unchanged desktop windowing. The screen captures are available in the article.

RESEARCHERS ARE USING AI TO DECODE THE HUMAN GENOME

AlphaGenome is an AI model that can make predictions about thousands of genes. It was trained on a vast wealth of molecular data, allowing it to predict things like whether a mutation will shut off a gene or switch it on at the wrong time. The model is being deployed for use in things like cancer research, but scientists are still wary of its results. AlphaGenome is still just a prediction tool, so scientists still need to go to the lab to verify its output.

VIDEO: CHINA'S 18 HUMANOID ROBOTS EMERGE FROM CRATES IN AN EX MACHINA-LIKE SCENE

LimX Dynamics has released a video showing 18 of its full-sized humanoid robots autonomously performing a coordinated routine. The showcase highlights how teams of robots could be deployed and operate on future manufacturing floors. LimX's robots run on the company's newly introduced COSA system, which allows multiple humanoid robots to function together autonomously. The COSA operating system unifies perception models, learned skills, memory, and basic emotional states for sustained physical interaction in real-world settings. The video is available in the article.

THE FIVE LEVELS: FROM SPICY AUTOCOMPLETE TO THE DARK FACTORY

The cost of code is dropping so fast that teams need to reconsider their tech debt payment plans. Smart teams are deferring payment on human hours today to pay them back with cheaper AI hours tomorrow. Cashing in on those cheap hours requires understanding how to move through the tiers of automation. Luckily, the federal government has already completed a roadmap for autonomous cars. The five levels of driving automation are a helpful guide on what companies should aim for.

THE 80% PROBLEM IN AGENTIC CODING

AI writing most of the code places a disproportionate emphasis on the human's role of owning outcomes, maintaining quality bars, and ensuring that tests actually validate behavior. The danger is that the AI succeeds so well that developers stop checking their outputs. AI is an amplifier of development practices. Bad processes will result in accumulated debt at an unprecedented speed.

AI ASSISTED INTERVIEWS

When faced with a problem, strong candidates stay calm, form precise hypotheses, and then systematically test one hypothesis at a time until they zero in on a solution. AI just accelerates this process. Weak candidates blindly try things, hoping something sticks. Their process remains sloppy when using AI. AI doesn't by default make people perform better, it amplifies people's existing patterns.

AMAZON LAYING OFF ABOUT 16,000 CORPORATE WORKERS IN LATEST ANTI-BUREAUCRACY PUSH

Amazon announced yesterday that it plans to eliminate about 16,000 corporate jobs in its second round of job cuts since last October. The layoffs are part of an ongoing effort to strengthen the organization by reducing layers, increasing ownership, and removing bureaucracy. 14,000 employees were let go across Amazon's corporate workforce during October's layoffs. Amazon has been cutting costs across its businesses so that it can invest more in AI and the rapid build-out of data centers. It recently closed its Fresh and Go grocery chains after years of experimentation.

AUTOMATING BIOLOGY

Biology is wildly complex, and our understanding of biological systems is just scratching the surface. Automating biology will require significant investment to achieve exit velocity. However, once we achieve it, we'll be able to explore the galaxies of genes, proteins, and microbes living all around us. These developments will pave the way for novel therapeutics that will improve health and longevity, boost biomanufacturing, and more.

TRY TEXT SCALING SUPPORT IN CHROME CANARY

The new 'meta name=text-scale' HTML tag informs browsers that websites are designed to still work if users increase their OS text size. To support text scaling, developers should avoid overriding the initial font size, only use font-relative units for content, and test on devices to quickly figure out problem areas and think about how to adapt their layouts. The tag is currently supported in Chrome Canary with the 'Experimental Web Platform features' flag enabled. Support in other browsers will hopefully come later this year.

“IG IS A DRUG”: INTERNAL MESSAGES MAY DOOM META AT SOCIAL MEDIA ADDICTION TRIAL

A high-profile lawsuit against Meta and YouTube that alleges the companies caused psychological harm by designing features like infinite scroll and autoplay is set to begin this week. The case could set a meaningful precedent for hundreds of other complaints. TikTok and Snapchat were also targeted by the lawsuit, but both have settled. The lawsuit seeks untold damages, including potentially punitive damages, to help the plaintiff's family recoup losses and to punish social media companies and deter them from promoting harmful features to kids.

Achieving this goal will depend primarily on more and better data, which is bottlenecked by funding and the achievement of some key technological breakthroughs. It will soon be feasible thanks to a couple of recent advances. We are nearly capable of overcoming such bottlenecks at the scale of insect-sized organisms.

SEEING LIKE A SEDAN

Tesla robotaxis navigate using an array of cameras, while Waymos uses LIDAR technology along with a suite of complementary sensors. Tesla challenged convention, but it has quietly reintroduced radar, and it is possible it may bring in other modalities. The paths for the two companies seem likely to converge in the future. This means that instead of debating whether cameras or LIDAR is better, regulators should be asking whether robotaxis in general are as safe as human drivers.
