Fron an ATC point of view when we went from paper strips,chinagraphs,pens, etc, to computers the problem we found was getting the older controller to use and trust the automation (computers) and the younger ones not to 'trust' the automation.
That is, for the older ones to use the new tools and the younger ones not to have blind faith in them.
Automation is an aid to doing our job, ultimately it is the humans responsibility to make sure the the computer is being used appropriately and intervene when it is not. The computer is only as good as the information in it.
As regards to UAV type operations, personally, I wouldn't get on an aircraft where the people flying don't have as much at stake as getting it back on the ground safely as I do.
