Yeah when you take 2 steps back, ignore IT for a second and look on whole mankind, there are hundreds of millions of jobs that could be called nonsensical from certain points of view. We are not above this in any meaningful ways, maybe its just a bit more obvious to keen eye.

Yet society and economy keeps going and nobody apart from some academic discussions really cares. I mean companies have 100% incentive to trim fat to raise income yet they only do the least minimum.
