Are you afraid your coding legacy would be tarnished?
We toil to create beautiful code using all our means and faculties and proudly (some of us do!) add our name as authors. Everything we write is consigned to posterity. It is our legacy. As if to proclaim, "I solved this problem!". But sometimes it isn't easy to detach oneself from one's creations. Just like parents never tire from worrying about their children's new-found errant ways, it breaks our hearts to see our code handled by chimps.
Oh, we are so full or ourselves.
