The love of science, the exploratory nature, the conservative(somewhat) nature of society, the emphasis on intellectual pursuits, the remaining bits and traces of mysticism, etc...
You don't find any of that on Earth?
90 years from, what ENT? Cochrane? Now?Yes but they were re-shaped in the Vulcan mode.
T'Pol stated the Vulcans had been on earth for ninety years-that is a long time. And Vulcan ideology would in that time I think have filtered into humanity's collective conscious and unconscious.
That still leaves centuries of exploratory and scientific curiosity. Good bad or otherwise that includes Galileo, Einstein, Von Braun, Goddard, um, pretty much everyone in the Enterprise opening credits. AND the Soviets.
Re-shaped how? I didn't watch much of ENT, but I saw enough to see a humanity that was straining at the "leash", eager to get "out there" to the shock and dismay of, among others, the Vulcans.
And before that little bit of retconing we saw people painted as aching to boldly go, setting up shop on any piece of dirt they could find, finding new ways to get there, new things to do when they did. Kirk's argument to Sarek (by way of Amanda) was that Starfleet was an opportunity for scientific advancement not afforded by staying at home like the Vulcans.
I fail to see "the Vulcan mode" anywhere in TOS, TNG, or even ENT. Not in the present day and certainly not in the heyday of NASA when Star Trek was born.
