"Enlightenment" or "super-concious awareness" is not dependent on a "free humanity" (whether ...that freedom is somehow provided by AI or any other tech).

Humans will always find a way to enslave themselves, regardless of the level of comfort and health. Rather, all of those other facets will only be "beneficial" if the sea level of "humanity" achieves its cosmic destiny and people begin to embrace soul contact DESPITE the current levels of mundane toxicity in the spiritual atmosphere.

All external circumstance (for individual as well as group) simply mirrors internal state... that latter drives the former, advanced AI and metallurgical breakthroughs notwithstanding.
