>Lots of doctors and automotive engineers just do their job and then come home, in fact most employees don't come home and continue to work on semi work related things on their spare time. My wife is a civil engineer and yet she doesn't build a 1/16 scale bridge in our basement when she comes home. Does that make her a bad civil engineer?
Perhaps not the best example you could have chosen: Physicians and licensed engineers do have mandatory continuing education requirements that more or less require them to be learning for a lifetime.
That's part of the tradeoff for software development not being a licensed and regulated profession. (The other half of the tradeoff being that anyone, regardless of education or credentials, can be a software developer.) You can't have your cake and eat it too.
