Basically it's a change that we'll have to adapt to.
Whether that's interpreted as good or not good will vary from person to person but (so far at least) our species has coped with change.
In music (which AI is getting quite good at creating such as
here) it's just one more step from regular instruments to a $100 program that can synth anything (Ableton's starter version).
In art, I'm not an expert but I'd struggle to separate some genres - I like some of the
sci-fi stuff for instance.
Words vary but it's getting better and it has passed the
bar exam 
Fun times!
