Medicine may be more mature as an industry where education takes a little longer but it is not much different from software. Many of the best doctors (that I've had and know of) started out helping their parents with labwork as kids or interning at university labs in high school, helping with real research into biology or medicine. Likewise, there is a significant gulf between the doctors who chose the career because they are passionate about helping people and those who do it for the money or because of cultural pressure.

There's so much work to do in both fields and we need all kinds of people, but there is certainly a difference in work environment when the team is dominated by one type or the other.
