You lost me there. This is the fundamental problem with Scrum; this type of paternalism where "programmer" is a synonym for "idiotic code monkey", borderline autistic who isn't capable of dealing with demand from the outside. And all programmers are the same, all organisations are the same and all type of development work is the same. Everywhere. If only we would be doing "Agile" right.
