Even Spock has the most interesting opinion regarding modern technology in "Way to Eden" (not a popular episode but I always found this quote quite informative):We never went to Earth in TOS, we don't know how "happy" it was. Seems there was a fair amount of "corruption" in the Federation. Captains going mad with power. People enslaved on Ardana. Self serving bureaucrats at every turn. Trigger happy miners.
KIRK: Well. But they've rejected all that and all that this technology provides. And they seek the primitive.
SPOCK: There are many who are uncomfortable with what we have created. It is almost a biological rebellion. A profound revulsion against the planned communities, the programming, the sterilised, artfully balanced atmospheres. They hunger for an Eden where spring comes.
KIRK: All do. The cave is deep in our memory.
SPOCK: Yes, that is true, Captain.
