I know this is how people in the 80s and 90 imagined the future and a lot of concepts were probably too far fetched for them.
BUT... why arent they using drones to explore planets? why are there not more drone-spaceships? why does enterprise need a crew to begin with? Why is there so little automation? Why so few uses of AI in general?
I am saying this as a star trek the next generation person. I'd also expect them to have full video and sensory streams of any surface mission teams.
It's a military / government ship. There is no real privacy.
Everyone can read your personal logs if there's a good enough reason. Anyone can just ask the computer where anyone is at any time. People can just barge into your holodeck program. Anyone, from civilians to bartenders can just call up the bridge and talk to the captain whenever they want. People are just expected to control themselves.
I think of it like how people don't need to carry defensive weapons now, while a knife was very common in the past. People are just expected to control themselves and not rob random strangers today.
So then the lack of cameras seems like a huge security oversight.
