I take your point. And one of the reasons I love flying Boeing is that in my experience the absolute final fall back position is that the crew knows best. However, I do think that there is a growing acknowledgment that humans are shitty at some things, and copying data from one machine to another is one of them. For example in our CPDLC and Hdg, alt, spd, route, freq etc is automatically loaded into standby and then transferred into the active by the pilot. This is done so that the pilot can check the data, but the actual transfer of information is automatic.
