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.
There was an episode of TNG where a “passenger” got onto ship’s comms and was contacting Picard on the bridge. When Picard told the guy that the comms were reserved for ship’s business, the guy asked why they weren’t restricted, if that was the case. Picard said that was unnecessary as people in Star Fleet generally just…behave themselves.
That did change overtime though. They mentioned in Lower Decks that they beefed up security after the Pakleds attacks, which leads to Boimler not even being able to open doors (or activate emergency systems lol)
That’s a totally insane explanation, though. Lots of people are on the ship at all times who aren’t members of the crew, and that’s before you even consider things like hostile boarding parties.
