Regarding your first question, everyone would be realizing the same thing, however, cultural, age and experience filters do remain, so it would be perceived differently by a Hindu, a Jane, a Jew, a Christian and all other add-ons. Imagine you download Word for Apple comps and then one for windows. They are essentially the same but are being seen through different platforms. While not much difference there would certainly be some. If everyone ''got it'' then I can assure you this world would be very, very different and most probably go poof!
Your second question doesn't make sense to me, so sorry, no answer on that one.
Love ya, Jed.
