This is the theory, and it can work if done properly. However, just like in a GOTO-ridden language, modern distributed systems are extremely difficult to setup in this optimal way. The more components we have in our distributed system, the harder it becomes to have any sense of safety and correctness. No wonder we started to see systems imploding worldwide as it happened last week.
