Still must be defined what is exactly human conciousness, and if have any meaning with that definition the idea of a shared conciousness.

But shared conciousness is not needed, just rising the abstraction level and watching how a society (or mankind) behaves as a whole would be a good hint on what could happen. And the problem is that what drives mankind right now is the money meme, not the preservation of the human race, or going to the stars, or preserve the ecosystem we depend on for a foreseeable future. That may be our great filter.
