What happened

In England, Luke Ashton died by suicide on April 22, 2021 after a longstanding gambling disorder. A 2023 inquest and subsequent Prevention of Future Deaths report found that Betfair had assessed him as a low-risk gambler, did not meaningfully intervene between 2019 and his death, and used an algorithm that failed to flag his escalating gambling activity even as his betting intensified and his financial exposure grew.

  • Type 2: Bigger than expected

    Harm can result from AI that was not expected to have a large impact at all, such as a lab leak, a surprisingly addictive open-source product, or an unexpected repurposing of a research prototype.

  • Type 3: Worse than expected

    AI intended to have a large societal impact can turn out harmful by mistake, such as a popular product that creates problems and partially solves them only for its users.
