Self-Supervised Learning [pdf]
If we can use GANs to produce believable images of a subject and we can identify whether a video frame can exist between two others, it seems like we can produce infinitely high framerate videos that look like they were captured that way. This also means we can make slow motion video when we didn't record at a high framerate. I think with that, colorization, and possibly similar tools for audio, we might see some amazing recreations of classic performances.
