Lighthouse

Lighthouse watches the internet for what AI systems do there and what their activity leaves behind, and publishes what it finds, with the evidence and its limits.

The map

The map brings partial views of the internet together with the edges of each instrument stated. Its findings are reviewed against sources; the observation catalogue and investigations link to the working records. An unobserved region is not an empty one.

  2. What AI activity costs the shared internet
