I don't think artists have anything to fear, unless they're willing to keep on the illustration pumping work, however those that are master of their craft they'll keep being relevant on their expertise, you can some artists still working with oil painting. I'm sure as the tools keep advancing you might see an artist, that can make his own U149 or ML fan seasions of anime. Like those touhou animes but far less people involved. Meanwhile companies will focus on making the im@s world where you can chat with your idol in real time.
