Sorry if that wasn't clear. I didn't mean that artists are less skilled today, but that realism and technical skill are generally considered less important today than in the past. "Top" artists today are usually not considered so because they have amazing technical skills at drawing/painting/etc. The metrics for success are a bunch of other things I won't get into here, but hyperrealistic portraits aren't typically considered to be art worthy of being in Gagosian and Hauser & Wirth (two of the top contemporary art galleries.) Whereas they would have been in the era of say, Dürer.
Video games, movies, etc. typically do care more about skill and realism, but they're a different thing from "fine art", i.e., art in art galleries.
