The Sussman deems it unscientific and ultimately destructive.
Indeed, one often hears arguments against building flexibility into an engineered system. For example, in the philosophy of the computer language Python it is claimed: “There should be one — and preferably only one — obvious way to do it.” Science does not usually proceed this way: In classical mechanics, for example, one can construct equations of motion using Newtonian vectoral mechanics, or using a Lagrangian or Hamiltonian variational formulation. In the cases where all three approaches are applicable they are equivalent, but each has its advantages in particular contexts. http://swiss.csail.mit.edu/classes/symbolic/spring07/readings/robust-systems.pdf
