I'd say that in CS, there's a lot more transferrable knowledge. In medicine, there's a lot of specialization and niche knowledge. The cardiologist would know very little about orthopaedic specialist, for instance. I was a GP myself, and likely knew more about medicine & surgery in general. Although I had less specific knowledge, I could integrate information better (eg. Project manager, if you will, vs database specialist). So yes -- in CS, if you work in an area with a lot of general knowledge -- you are likely to get up to speed faster. In medicine, if you're a GP, you can probably undergo additional specialist training much quicker than someone who first pursued a single specialty first.
