I'd say the focus on loss only furthers our suffering and it seems like you firmly believe that this transition is going to happen eventually to humankind. So I'd suggest gearing your question towards what we have to gain. Access to every thought ever thought and every feeling ever felt seems overwhelming maybe we lost that universal consciousness to gain individual coherent 'memory' I believe that every moment is a lifetime and I feel like I can go through many life times in a matter of seconds it's quite amazing how perception is altered at higher frequencies
