From the article:
Soon, I went to get Roberta. I told her the news [about rediscovering his art] and asked her to come see. She came into my office and started looking. For a long time. Longer than I had. One by one. Studying, not saying a word. After a while she turned to me and said, “They’re okay.” Stricken, I said, “Okay?! What do you mean ‘okay’? I think they’re beautiful. Aren’t they great?” She turned back to the drawings, looked a little longer, and finally said, “They’re generic. And impersonal. No one would know what these are about. And what’s with the triangles? Are they supposed to be women?” I shot back, “No! They’re Hell!” She talked about how many artists “never get better than their first work.” And just like that, I was right back to where I was when I quit: crushed, in crisis, frozen, panicky.

Most of contemporary art is mediocre looking work which sinks or floats based on fashion, connections and marketing.
It is largely a trivial, social, reputation-driven thing, funded by idiots with pretensions... But that doesn't mean there isn't an intellectual side to it, pursued by people who actually care about art and what it could be.
and by being more connected to the common experience, it now sinks or floats based on whether it says something that feels true or insightful or relevant to our time. the key piece is that the average viewer can know wtf it's even talking about without much background or context.
