I ended up skimming a lot of it, though I closely read the beginning and the end. This is not a vision of humanity I agree with. Technology is not the only path towards expansion of consciousness, even though in this day and age, it appears so. The wonders, marvels, and growth described in this story can be experienced through other means. To act and build as if it is the only path is, in my opinion, deeply misguided…
Part of the magic of this story is that it can change what you agree with (as it did for me.) Not saying it will do the same for you, but it is a compelling vision; I can't think of other ways to get there without getting unscientific.
