I’ve spotted a few instances of discussion about deepfake ideas, and now that it’s becoming increasingly viable, I thought I might set up an index thread to aggregate all of those ideas, and link to their sources and implementations where possible.

I’m not listing these with any bias or preference, I’ll put all ideas here in the OP, leaving discussion of whether we should for the thread itself. It’s OK for these ideas to be a bit extreme here, I reckon, because the tech will only get better and then we’ll blink and find these viable. I’ll also include things which aren’t technically deepfakes but which serve a similar purpose, like Snoke tanks into Palpatine tanks.

Thanks also to oojason for linking me to some core resources for making this initial list easier. Feel free to chuck some more ideas out there and I’ll add them into this list.
