THE OPEN WEB IS SHIFTING FROM AN AUDIENCE ECONOMY TO A CONTEXT ECONOMY

The next phase of ad tech is shifting from knowing who someone is to understanding what's happening around them right now. Instead of relying on fixed audience segments built from past behavior, new bidding infrastructure lets ad auctions read signals like timing and nearby activity in real time. Containerizing that decision-making inside the auction itself cuts response times by roughly 80%, giving algorithms enough time to weigh context instead of just matching an ID to a segment. Advertising stops chasing who people are and starts responding to the moment they're actually in.

UBER AND WAYMO ARE SPARRING. THE ROBOTAXI FUTURE HAS ARRIVED

Waymo and Uber are nominally partners. However, these days, the two companies are trading thinly veiled jabs in a gathering lobbying battle. An Uber representative highlighted at a public hearing this week how the company's drivers spend their earnings and pay taxes locally, while robotaxi profits flow to unnamed companies based elsewhere. A Waymo representative conceded that robotaxis would mean job losses, but noted that rideshare companies control drivers' earnings and are taking a significant chunk for themselves.

ALZHEIMER'S BLOOD TESTS OFFER NEW PROMISE TO DIAGNOSE AND PREDICT THE DISEASE

Blood tests for Alzheimer's disease could eventually transform the way the disease is diagnosed and even predict who might develop it and when. There are still questions about their accuracy, so they shouldn't be used diagnostically for people who don't have cognitive impairment. However, they appear to be effective for predicting risk when paired with other factors. There are currently no treatment options available for people without symptoms, but that could change in the next couple of years as some therapies are currently in clinical trials.

THE FIGHT OVER HUMANOID ROBOTS HAS SHUT DOWN A CAR FACTORY FOR THE FIRST TIME

Hyundai's auto workers in South Korea have gone on a partial strike to demand pre-emptive action in response to the threat of humanoid robots. Workers are demanding job security against future industrial shifts as humanoid robot technology improves. Hyundai plans to deploy its Atlas humanoid robot by 2028 at its nonunionized Metaplant factory complex in Georgia. The company says it is committed to constructive engagement with the union to reach an agreement that supports the long-term interests of both employees and the company.

WHY WE STOPPED USING SDKS

SDKs are supposed to save developers time, but AI has changed the cost curve. Integrating with an SDK is often as much work as calling the HTTP API directly. It is now cheap to write a tailored REST client for exactly the endpoints developers need to use while providing better unified observability. Instead of shipping SDKs, companies will likely start shipping agent skills that teach agents how to call the API correctly, reuse the right patterns, and avoid pushing every runtime call through a vendor package.

THE MARGINAL COST OF CORRECTNESS

The marginal cost of correctness is going to zero. Engineers used to be able to differentiate themselves with raw technical talent, but this is becoming less true as agents are empowering anyone to write correct code. The most important skills to develop now are the ability to smell things out that just aren't right and the willpower to make them so.
