Collective unconscious and memory is just logical. We all come from the same place, so it only makes sense that some of those memories were passed down. I think science has now shown that memory can be stored in DNA, so that would seem to give firm support to Jung's ideas. But I'm wondering going forward if we will come together in a much more literal way. If that step to interfacing humans with machines (and the internet) comes true, then it seems inevitable that it happens.
