'Adding value' is a very interesting statement and way to judge the worth of something. Adding value to who? And if that value add also causes massive harms, how do we reconcile that?

Corp IT does not exist in a vacuum. Understanding the why of that isn't a 'you should just accept this' but more 'how can we make this better and avoid mistakes already made by others'. I will always point to aviation and 'bold text is written in blood' as a great model to understand all of this not as a blocker but, instead, as a building block.
