Science is not Politics

“Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results.” – Michael Crichton

Looks unfortunate that most software developers have forgot this point.
Many modern programming languages just try to reach a consensus instead of doing things right. Let's observe how Javascript, the most widely used language today still keeps "null" and "nondefined" types around even if science says they must be dropped (backward compatibility is just an excuse, not a reason).
