Why would you want to force someone to use a single aesthetic category?
Why would you want to limit the number of admissible aesthetic categories?
If the success of specific aesthetic categories varies from one
programmer to another, wouldn't it be best to let everyone decide
themselves what aesthetic category to use in order to maximize
productivity? Of course, it should be a well-informed decision.
The problem with the state of computer science today isn't that everyone
uses Java. The problem is that everyone thinks that there should be only
