Considering how CGI has always in the past "looked dated" a few years out, I'd tend to agree. I don't believe that modern CGI is so much better that it won't look dated 10-15 years from now if not sooner. I think that some of the traditional ways of shooting films (non or pre-CGI) hold up incredibly well. Like the opening scene in Bladerunner- that was much more expensive to shoot than using CGI today, but it has held up incredibly well. Compare it to CGI films from 5 years ago- they looked good at the time, but now, not so much.
