Rule of Three. about codebase HOT 4 CLOSED

I find OOP technically unsound. It attempts to decompose the world in terms of interfaces that vary on a 
single type. To deal with the real problems you need multisorted algebras - families of interfaces that span
 multiple types. I find OOP philosophically unsound. It claims that everything is an object. Even if it is true 
it is not very interesting - saying that everything is an object is saying nothing at all. I find OOP 
methodologically wrong. It starts with classes. It is as if mathematicians would start with axioms. You do 
not start with axioms - you start with proofs. Only when you have found a bunch of related proofs, can you
 come up with axioms. You end with axioms. The same thing is true in programming: you have to start 
with interesting algorithms. Only when you understand them well, can you come up with an interface that
 will let them work."
