Tell that to citizens who can't register for unemployment or fill their taxes because the callback hell doesn't work as it should.

These two examples are interesting. They're both cases where what was being created was a system where software was an important component, as opposed to the software written by the vast majority of us where the hardware components of the system are always the same (monitor, keyboard, etc.) This is the same distinction in Diamond v Diehr for when software might be included in a patent. I always thought the US Supreme Court made a good decision there. Unfortunately they were later overruled by lower courts. (For legal experts out there about to correct me and say that lower courts can't overrule higher courts, I wish you were right.)
