At Massive Scale, Nothing Is Just a Technical Decision
There is a version of engineering that most developers understand intuitively: you identify a problem, you find an efficient solution, you ship, you iterate. The logic is clean. The feedback loops are tight. If something breaks, the cost is contained. Then there is engineering at media scale. And almost everything about how you were trained to think will mislead you. I do not mean that the problems become harder, though they do. I mean that the nature of the problem changes entirely. At a cert
