> * Hardware became far more complex. A modern video card or anything else is its own computer, with a very uncomfortable amount of state and access to the host. If your video card driver does something wrong and crashes it's by no means a given that the situation is recoverable by rebooting the driver -- the video card itself may be left in some weird state.

The rest of your points make sense but I don't understand fully how this is an argument for monoliths? Isn't recovery from an unknown state an equally hard problem in both cases?
