I was going to tell a science fiction story about faceswapping, and mass blackmail. Then the news broke about unethical faceswapping videos, and software designed and marketed for creating them: and I realised the future had arrived faster than I thought.
(This was originally a talk given at An Evening of Unnecessary Detail earlier this week, but I managed to mangle the audio recording settings, so I rerecorded it in a muddy park! It’s not the same without the audience, but hopefully it’s close enough.)
