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 can be used that way, sure, and the Very Civilized Starfleet uses them conservatively. But a beam weapon that is capable of disintegrating anything (unshielded) that it touches is crazy powerful. And those are only the hand phasers; we don’t often see the phaser rifles, but holy heck. If phasers scale like projectile weapons do, a single phaser rifle would be capable of vaporizing entire buildings, tanks, aircraft.
