You're dead wrong about IT not requiring a comparable level of skill and knowledge as the legal profession or medicine. I agree with the original poster and with you that we should excercise a comparable level of professionalism as doctors or lawyers but our professions have a lot more in common than you think - particularly software development or hardware engineering.
For example the acronym-of-the-week hamster wheel never stops turning and like lawyers and docs we have to maintain a constant state of continually learning about the latest developments in technology - except here our job is harder - since doctors have JAMA and lawyers have law review - all of which are heavily peer reviewed - whereas the technology press has no editorial standards at all. We have to apply a pretty good BS filter while still staying current.
And by the right set of rationalizations medicine and law are also support fields.
