Everything dates, that doesn't mean it's bad. Our vision of the future changes every year as technology updates and makes things we projected outmoded. Is the TOS Enterprise bridge dated? Yes, in the details. Looking at a flashing light and getting tons of info from it is very much of the 60's. In the design itself, the broad strokes, it still holds up because it mostly makes sense.
Like fins on a Cadillac, it was cool but is now a reflection of the way we used to think. It doesn't look bad to me, and still looks better than the Apple Store / Gil Gerard style currently being used (and I'm not a nuTrek basher really). The design concept is solid enough to have survived the decades with only tech updates.
