Re: And your point is?
You can be smart at one thing and dumb as a housebrick at others - lawyers fall for 419 scams, system administrators still call roofing companies. Different expertise progresses a society - it is impossible to know it all, so people specialise, and swap skills (often via the medium of a financial economy, too).
I'd rather that doctor got on with being dumb at IT and smart at fixing people rather than being shit at both jobs.
