Most programmers today have never seen a single user, single process machine. They did not experience a constrained hardware or used a compiled language. They just want to layer their over-bloated lego pieces until the job gets done. Have a roach infestation? Bring in the entire military and all intelligence agencies to do the job. Most of them won't even know theory. Let's just layer more ifs and more logic until it is done. State machines? Constraint solvers? Logarithmic complexity? That's the job of the next developer. I rely on pure IQ.
