Amazon is retiring one of its oldest and strangest services. AWS said it plans to shut down Mechanical Turk on September 30, 2026, following an assessment of the service, according to reporting by Annie Palmer at CNBC that was aggregated by Techmeme.
Mechanical Turk launched in 2005 as a way to farm out tasks that are easy for humans to complete but too challenging for computers. Businesses and researchers posted small jobs — the platform's crowdsourced workforce picked them up and completed them for pay. Jeff Bezos famously described the arrangement as "artificial artificial intelligence," a joke about software that looks automated from the outside but runs on people underneath. CNBC notes the platform is 21 years old.
The name itself was a reference to that same sleight of hand: the original 18th-century Mechanical Turk was a chess-playing automaton with a human hidden inside.
For two decades, the service occupied an unusual place in the tech world. It was infrastructure for academic research, a source of the labeled data that machine learning systems train on, and a gig-work platform — all at once. CNBC frames the shutdown around Bezos's old label, which lands differently now that genuine artificial intelligence handles many of the tasks humans once picked up piecemeal on the platform.
AWS has not, per the available reporting, laid out a detailed rationale beyond saying the decision followed an assessment. That leaves roughly a year for the researchers, companies, and workers who rely on it to find alternatives.
Why it matters: Mechanical Turk was the clearest public example of how much human labor sits behind supposedly automated systems, and its closure marks the end of the era when that labor had a brand name and a front door.
