Amazon service Bezos once called 'artificial artificial intelligence' is shutting down

Why it matters

Mechanical Turk's closure signals a shift in how AI companies source training data and crowd labor — a workforce that has underpinned model development for two decades. The shutdown raises questions about what replaces human annotation in the AI supply chain.

Key signals

  • Mechanical Turk launched in 2005
  • Service described by Bezos as 'artificial artificial intelligence'
  • Platform enabled task completion too hard for early AI systems
  • Shutdown impacts workforce relying on gig annotation work
  • Timing suggests shift in AI data-sourcing strategy (2026)
  • Amazon Mechanical Turk launched in 2005
  • Platform used for tasks too hard for computers but easy for humans
  • Shutdown date not specified in article excerpt
  • Long-standing infrastructure for RLHF and dataset labeling in AI pipeline

The hook

Amazon is shutting down Mechanical Turk, the 21-year-old human-labor platform that powered AI training data collection.

Mechanical Turk launched in 2005 as a way to farm out tasks that are easy for humans to complete but too challenging for computers.
