Battlestar Galactica is case in point. Prior to the human genocide, the military was more like TNG's military. Their war ships had gift shops, everybody used networked computers even knowing that if the cylons attacked they could destroy their ships instantly that way.
Only Galactica had a gift shop, and that was because the ship was being decommissioned and turned into a museum.
The networked computers was a specific plot point to show how complacent humanity had become due to 40 years of no contact with the Cylons. Yeah, it was stupid of them, that was the point.
