>>Doctors notoriously fail to adopt (as a group) newer lessons until they are replaced, and lawyers have a similar problems when new areas of law open up (often in tech)

Even as individuals they need to adopt to newer lessons. If anything its harder in their case. Gaining a new skill or learning something new is way easier for an old programmer than for an old doctor to learn something new in their practice.

If you have chosen a knowledge based profession, you have to learn all life. Or its over.

These are like the fundamental rules of this game.
