They are quite different skills, I think. Being good at one doesn't tend to mean being good at the other (and this also applies to organisations: hardware companies will tend to suck at software by default and vice-versa. Not because they're necessarily anti-correlated but because they're sufficiently uncorrelated that they will tend to be average, i.e. bad in the area they aren't doing well in). But then there's a pretty wide spread of difficulty and skills in the individual parts of either which dwarfs any difference in the average.
