Let's not also forget another way in which CGI is detrimental to the film-making process: the fact that acting without any sort of frame of reference (i.e. against a blank green screen instead of on an actual set) does not encourage good performances by your actors. As CGI gets cheaper we can expect less and less use of actual sets.

Also, CGI replaces actual stunts and the danger associated with them. Most people would, of course, see this as a good thing, BUT IT IS NOT SO. The element of real danger adds to the films. This is one of the reasons I enjoy Jackie Chan's classic films; you have to respect a guy willing to die to entertain us! CGI encourages what Nietzsche called the "slave morality" in film-making.
