* edit for clarity: what would be commonly considered technical artistic effort, although a large % of graphic designers would disagree with that as composition is a skill, and conceptual artists would disagree due to the thought put in (which imo feels post-hoc but hey ho)
So, it's not that being technically spectacular in some arbitrary "really accurately painted or drawn picture of reality, like a photo" way makes art valuable (photography effectively destroyed that a long time ago, sorry!). It's that it has some special significance. If that significance is more than personal, as in it has some historical/cultural significance, then it becomes valuable. There's no point to it, it's art. So w/r/t original subject, above reasons make me think twice about any knee-jerk cynicism I have toward it (which I do have, I just have to have an open mind)
You had me until this bit
Mama! Yes but ....
