I love this article, and have thought a lot about many of the implicated topics, but I'm disappointed you left out the one most likely scenario!

The one where we take internal charge and charter of our human destiny, realizing that there is no evidence of God, or panpsychism, or last minute alien savior.

We have finally matured as a conscious species to architect our own escape hatch, and we are knee-deep in the process without, en masse, realizing it.

I'm broken-recording a little, but we have already escaped the pressured confines of our immediate natural environment, and we have quite adroitly forced the environment to adapt to us. Our next trick is to self-construct our future environment, which currently looks like a melding of the human mind/consciousness with its greatest tool, the "computer" (in quotes because the final 'product' will be so much more than a laptop).

We have already engineered artificial spaces where we can cohabit and interface with one another, soon getting to the point where we can literally share experiences, the first goal of any act of communication or understanding. From there, we will interact directly as ordered energy, being able to contribute and receive as individuated perspectives.

Perspectivism is key, because it is at the core of semi-random generated chance. Chance, whether by evolutionary mutation or universal non-constants are essential to collective organism improvement.

So the real afterlife scenario is as a Synthetic Self that will coincidence with other such selves to engender a Synthetic Species.

And that's where the fun really starts ;)

Sorry for the tirade, my main goal began as thanking you for an excellent article!
