Facebook admitted, at best nonchalantly, on Thursday that its super-soaraway AI algorithms failed to automatically detect the live-streamed video of last week's Christchurch mass murders.

The antisocial giant has repeatedly touted its fancy artificial intelligence and machine learning techniques as the way forward for tackling the spread of harmful content on its platform. Image-recognition software can’t catch everything, however, not even with Silicon Valley's finest and highly paid engineers working on the problem, so Facebook continues to rely on, surprise surprise, humans to pick up the slack in moderation.
