I'm not sure I'd agree there. Both programming and traditional art are creative disciplines. I'd argue that any creative discipline can be treated as an art.
I may have misread the comment that you originally replied to; my reading of golergka's original comment was simply to put .kkrieger in the correct context.
We expect certain things from games, and .kkrieger doesn't deliver on that front. In the context of the demoscene, it delivers in spades.
I thought you were originally objecting to the reclassification of the .kkreiger developers, gamedev -> demodev. A second reading suggests that maybe they don't consider .kkrieger to be art, in which case I disagree.
