Of course CGI will look shite, just as black and white movies look dated now, they still retain a value, the viewer is aware of their place in history. Toy Story already looks decidedly dated, but its still a good story to watch, the artform is still there.
The same can be said for electronic music. Early Detroit techno was made on the most basic of equipment, and it shows, but thats part of its charm. I don't think the digital era has affected music as an artform, its just swamped us with a vast wealth of music to choose from - we need to become better at filtering, find what you love, what speaks to you and hold on to it.
