Why do people choose IT as a career?

I believe that most people who choose IT as a career want to achieve order and balance. While the most complex issues in life revolve around people, early entrants to the career think that it is about the machine or the system and how it can always be made predictable and regular. Ironically, IT people eventually learn that IT is about enabling people and one cannot escape the people part. Many never really understand the complexity of the systems and begin to believe the system cannot be made predictable. Those that get it all in balance eventually understand the meaning of the word system and also understand that people are part of the system.
