I don't expect radiologists to have a good understanding of the software involved in the control loops for the equipment they operate. Why should a lawyer have to have a mental model or even understand how the pdf rendering engine works?

Have you ever had to actually react a document in acrobat pro? It's way more fiddly and easy to screw up than one would expect. Im not saying professionals shouldn't learn how to use their tools, but the UI in acrobat is so incredibly poor that I completely understand when reaction gers screwed up. Up thread there's an in complete but very extensive list of this exact thing happening over and over. Clearly there's a tools problem here. Actual life-critical systems aren't developed this way, if a plane keeps crashing due to the same failure we don't blame the pilot. Boeing tried to do that with the max, but they weren't able to successfully convince the industry that that was OK.
