More galactic era stuff (or maybe transhuman). Don't have a clue where they would go in the tech tree or their effects right now - just throwing ideas out. Each of these requires the previous:
Mind backup (obviously requires brain machine interfaces)
Mind virtualization (instantiate yourself in different places, or multiply)
Mind image reintegration (pull back instantiated partials into the aggregate whole taking their memories etc.)
Group mind (extend aggregation to the virtual images of a large number of originally separate individuals)
Overmind (group all minds of an entire civilization)
