Definitely plays well with the kind of scenarios the writers throw at them - you can pretty much expect any Starfleet officer, whether a commander or an ensign, to operate any system on the ship with at least some passing competence. There's no "I work in stellar cartography, I don't know which button fires torpedoes or how to turn on the bio-bed in sick bay" on a Starfleet ship, except when uttered as a joke (or with EMHs). Overkill in real life? Perhaps. But definitely reassuring. Hell, if someone really didn't know, they could expect "Computer, turn on the bio-bed 3" to just work - circling us back to the topic of what NLP and voice interfaces are good for.
