Curation, refinement and taste is practicially worthless on its own. The technical difficulty of art is the investment that makes it worth considering.
So if you are right, then art will pretty much be worthless in the future. You can just iterate over the search space defined by "good taste" and produce an infinite amount of good art for no work.
Curation is not worthless. It's the exact opposite, in the abundance of stuff, it's extremely valuable.
Search is not free, and it can never be free. What happens when search gets easier and easier is that your demands for quality and curation will get higher until all time saved in search efficiency is spent on search breadth.
