"Whenever I’ve approached a new system the bottleneck has never been writing more code. The bottleneck has always been in understanding all the implicit assumptions baked into the system that for one reason or another are essential to its correctness". Well.... I know the feels... Assumptions without "understanding" is like the sword of damocles. As you sway into the program itself, there's always this notion that "something" is not right. Or maybe our assumption is not good enough. Most of the time, unplanned assumptions make it harder to integrate "more" code in the long run.
