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.
I can't remember who said this in the show in Universe; maybe Janeway? But I think a similar question was posed, and the answer was that nobody would have anything to do if exploration was entirely automated. It's fun and exciting and gives people's lives meaning.
My headcanon is that many mundane things are automated, and we don't see them because they aren't plot-relevant.
Like pooping
I hate that this was the first thing I thought of. :)
