Re: Software engineering is an oxymoron.
One quote from TMMM is particularly relevant here: “The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination.”
Many of the professions quoted previously are rooted in basic laws of physics. Biology*, the root of medicine and pharmacy, is slightly less well tied down (we're usually pleased to get 2 sigma) but still based on the physical world. The difference between these and software is real.
* A long time ago there were threats to make the practice of various sciences dependent on membership of the relevant chartered institutions so I took the pre-emptive step of joining mine. If its regular publication was any guide it seemed to be largely populated by biology teachers and the best bit of said publication was the regular page of exam howlers.
