I think we'll eventually see hardware that cryptographically signs the content as soon as it is produced with timestamp, but then that could be fooled by someone creating a deepfake, projecting it on a high resolution screen and then photographing with another camera. Or we wouldn't believe things unless they are captured by multiple cameras at different angles and maybe future GANs will be able to cover that. We are seeing the beginning of an arms race!
