Management as a career is one of those areas. Really, the whole need for managers (especially "middle" managers) is to maintain a line of communication between the leader of an organization and its producers/workers. Doesn't the internet make this type of job obsolete? In an efficient pipeline (of information), aren't they just bottlenecks?
We're certainly not there yet, quite possibly still a long way away, but once we get to the point where dissemination of pertinent information is at maximum efficiency, we won't need these arbiters of information in the system anymore.
I think this ties in to PG's thoughts on people not being meant to have a boss (http://www.paulgraham.com/boss.html) as well as Berners-Lee's talk at TED about getting information onto the internet in as raw a form as possible.
