All parts in a system have a probability of failure. A bug in a well-engineered system is only a problem when a long series of things simultaneously go wrong. Tree Notation (2D languages), can be used at all layers, from microcode to assembly to system langs to interpreted langs to user facing high level langs. It's simplicity will decrease the probability of failure at each layer of the stack, causing a huge improvement in total reliability of systems. It even works great with paper! Easy to make fallbacks for when the network goes down.
