(Yes, I know there are a few exceptions to what I'm about to say):
- We will be able to have more honest conversations about important topics
- We will more easily be able to remove all of the remaining "us vs. them" human constructs
- We will - collectively - have better morals and ethics
- We will be freer to use our cognitive abilities
- We will get closer to truly implementing universal human rights
Other than that, not much
Thanks for answering those are interesting beliefs hard to either prove or disprove. They are also hard to value.
