When I read incident/accident reports, I almost always learn something useful that hopefully stops me following in their footsteps. Going with what information has been released so far, this accident appears that it will contribute precious little to the sum of aviation knowledge, apart from the extremely obvious.
Where I believe it will contribute however, is to the sense of how much distraction you allow. We all get distracted and as many on this thread have said it's a question of how long before we come back to the duties at hand.
After each such episodes of distraction
in the future you can now think about how long it took you to come back to the critical tasks and judge your own performance thinking about this accident.
