I just rewatched the first two episodes of DS9 since the first time they were on the air and it occurred to me, Miles O'Brien is extremely capable. He was transporter chief for years on the Enterprise-D, a seemingly specialized role, and once he is promoted off to DS9 he is basically chief engineer in everything but name. Was O'Brien just that amazing, as Lower Decks would have us believe (obviously he is amazing regardless)? Or are the people in the position of transporter operator severely over qualified? Or, perhaps, is transporter operation just that hard?
