Computer-generated photorealistic human beings

All of these people were created by computer.  We're quickly moving out of the uncanny valley.

Still shots don't quite capture the essence of the uncanny valley; how things move. Sturgeon's law will assure that most CG won't get the movement down correctly, so we will at least be weirded out by that. Conversely, there was a tech demo a little while ago that generated humanlike shapes in real time from multiple cameras:

Mr Kreylos, researcher at University of California, Davis, said in his blog that despite the low quality of the image, it still feels very real.

Again, still images don't quite convey this because movement seems to be a critical factor in how "uncanny" something looks to the human brain.

Escaping the uncanny valley is a matter of presentation, not technology, so I would not expect all CG to suddenly escape the valley. At least, not until computers can predict accurate-enough human movement for us.

That's certainly true.  On the other hand, not long ago, still images were well within the uncanny valley.  So progress is being made.

I think convincing CGI humans would have a massive impact in ways we can't even imagine.

Eerie.  Almost too realistic, if there is such a thing.

That's uncanny valley in a nutshell: If it's too close to being realistic while still displaying subtle hints of "not quite right", it's going to freak people out.
