So, this whole thing about reusable code is mostly a sham, right?
Obviously there are cases where code is being reused, I'm not denying that. But if code was really truly reusable, in the deep meaning that OOP textbooks seem to indicate when they use the word, then all of us nice programmers would be out of a job.
Not entirely true, since the Moore's law ensures that the hardware platform is always mutating below us (though that looks like it might be coming to and end as we are starting to hit some real physical limitations, like not wanting a phone that burns through your thigh, but who knows. If I had wanted to deal with real world objects and their disgusting fleshy materiality, I obviously wouldn't have become a programmer. Now back to our regular programming: building virtual sand castles out of imagination sand. But I digress. No really?)
And also, I guess, we might have to add some code to this perfect reusable code base whenever some truly new thing is discovered. Like when they confirmed the existence of the Higg's boson. We would have to add a couple of lines of code for that.
But all in all there sure would be a hell of a lot fewer of us.
