Some interesting ideas here.
It's great how the mind works, you can think to yourself that you have it all worked out, even find people that think along the same lines as you, and then something new pops up and that that was so true doesn't quite fit anymore.
It's safe to say none of us know where we are headed, we just think we might have an idea.
IMO the most important thing is not to let the ego take over and look down on others just because you think you know something they don't, only an ars ehole would do such a thing, and my bet is that they don't allow over inflated egos in the next dimension
