So it's really good, and we have reason to believe, never again, anything that happens in a video. Unless there's a super-product somewhere to authenticate footage?
It seems like this super-product will have to be a thing soon or we will have to just stop using video evidence in court and other critical applications
Now that they've broken the ability to trust video, they're looking to build it back, as long as you're allowed to use the tools:

(and the previous SynthID: https://deepmind.google/blog/identifying-ai-generated-images...)
But it very much is "close the barn door after the horse has bolted and the barn has otherwise burned down".
