This blend of mindless contrarianism gets tiresome. If this discussion was about hand-writing, you'd be accusing left-ti-right languages of being pulled out of the ass as well just because it's the standard shared by most.

People feel the need to plan work, estimate work effort, and allocate resources to get stuff done. Some people adopted these methods and they get value out of them. Not everyone has the luxury of picking up tickets created by magic and "it's done when it's done".

If you have a better way of doing this then be my guest and use it, but I have a nagging feeling you'd shit on that too just to feel smarter than everyone.
