I literally just got flashbacks of Scotty trashing the transwarp in Star Trek 3 reading this.
That doesn't work as an analogy, though, because transwarp was an attempt to do something new, while photorealistic CGI of human characters is an attempt to find a more complicated way of doing something that can already be done far more effectively by simpler means. It's like going to the trouble and expense of building an elaborate Rube Goldberg device to open your door when you could just reach out and turn the handle. Why bother?
The value of CGI is its ability to create reasonably realistic images of things that don't exist in real life, or that would be too impractical to depict for real. It seems pointless to strive to use it to duplicate things that do exist already. If you want images of ordinary human beings, there are plenty of real ones you can use.
