If you think about it, in modern world, the least impressive thing about art is the skill.(Not saying skill is unnecessary, like any other field, you do need it, but all I am saying is skill is not the only thing that is valued in modern art)
Nowadays with modern photo editing softwares and filters, its possible for you right now to follow photoshop articles and turn your own smartphone photo into something that looks like Da Vinci painted it.
Hell, you don't even need to read any article. here, try it yourself for android or if you are a iphone user.
Skill is not the priority in modern art in the age of the internet. Why do you want a "realistic" painting that took 6 months to paint when a picture with a silly smartphone app filter does the job much better in a few seconds?
There is a new 3D printer created by a researcher that LITERALLY renders identical replicas of fine art paintings.
This is why modern art movement values the concepts and expression, how it effects the viewer more, etc.
