Proc gen makes a dose of art go further by diluting it. Good or bad, it means less of the artist in each bite. Where proc gen is strictly necessary i.e. infinite variation, the focus of the artist will be almost absent on average.

A tragic waste when one could be examining one's navel or shouting at traffic.
