There's another risk - which is rare events. Basically most of the reason why these workflows are not automated already is that there are a host of "once a week per operative" corner cases that don't show in the data for a long time, and when they do show they don't show as anything but noise. But this is where the human intelligence is spent and this is why the jobs are so hard to automate.
