Well going even beyond that. There's entire populations of people barely living above the stone age, not to mention uncontacted tribes still out there in the world. It provides a fascinating spectrum of experiences.

I guess my point is any large enough group of beings will have a variety of responses ranging from embracing new ideas and information wholeheartedly or rejecting them out of fear and ignorance and every possible combination of response in between. And it can be tricky to figure out which sub-group should represent the whole in these sort of blanket statements about how "they" would "feel" about an arbitrary bit of knowledge that they couldn't have foreseen discovering.
