There's no predisposition for them to not succeed at it either on account of them being technical. That's my point, drawing a technical/non-technical dichotomy for who is best suited a priori for management (let alone organizing Christmas parties) is silly, and extremely old fashioned given the broad successes of technical people switching to management at every level from front line to CEO over the last decades.
