I love this idea. In the early days of computing computers were claimed to always be deterministic. Give it the same inputs and you get the same outputs. Little by little that disappeared, with interrupts, with multithreading, with human derived inputs, with multitasking, with distributed processing, until today computers and applications are often not deterministic at all, and it does indeed make them very difficult to test. Bringing back the determinism may not only be good for testing, it seems likely to improve reliability. While I see how this is great for distributed databases I wonder if it has application when inputs are inherently non-deterministic (e.g., human input, sensor derived inputs).
