Pretend you’re about to invest years of effort and place your economic future on one of the following:
(a) A business totally dependent upon the fact that Gmail will always exist, or
(b) A business dependent upon email on any platform.
Why is it that “b” is an obvious choice in this pretend exercise, but that, for hospital-based physicians, almost all have chosen to stake real years of effort and their actual economic future on a single relationship between their group and a hospital?
