The problem with this is that then there is no institutional memory. Many student groups in colleges (at least at my college) fight the same problems in a recurring cycle every 4 years, because no one remembers why it didn't work out last time - the groups that avoid this are the ones that maintain connections with alumni or have a stable mentor. And this is for small groups that know each other well. If you had a corporation with 100s of people, it couldn't hold itself together with 25-30% annual employee turnover.

This articles mentality only really works if you are being hired to do a specific project, as an independent contractor, in the context of a larger team. Its also better for young people whose skill set is changing rapidly and may become better suited to different positions more quickly, as opposed to someone who has years of domain expertise and needs stability.
