The other great development has been in photography, but that too was influenced by Conceptual art.
Banal ideas cannot be rescued by beautiful execution.
Unless you're involved with thinking about what you're doing, you end up doing the same thing over and over, and that becomes tedious and, in the end, defeating.
The idea part is simple but the visual perception is complex.
Conceptual art is only good if the idea is good.
The artist is seen like a producer of commodities, like a factory that turns out refrigerators.
