Political deepfakes (notably the one we're all seeing *every other post* of Nigel Farage terrorising Andrew Bailey in the Question Time studio) are still in their mischievous, experimental adolescence, but their creators will soon be minded to deploy them at high speed, and at sensitively plausible moments, putting those they depict at dizzying pains to deny their truth. Our reactions to these jankily-rendered fever dreams are currently based on what they show us, but deepfakes will only be fully weaponised once they're strategically released into the stream of real-time events. It won't be what we see, but when we see it, that will be the difference.
