Not downplaying the amazing progress, but even the video showcases have some weird uncanny valley effects. The winged horse one in particular - the wings and legs morph, the wing on the left disappears and reappears through the tail.

This stuff is a little ways off, but still some amazing effects here. I think it will be a little bit before it is sufficient for production use in any real commercial situation. There's something unsettling about all of the videos generated here.
