Well I’m stumped. You write a long book mostly on the details of genetic engineering, saying we should use it to slowly change humans and their allied plants and animals, so that in 500 years we could launch them out to the cosmos, to arrive at other stars in a few thousand years.
I say, no, long before then artificial minds and life should have thoroughly replaced biology. A new kind of life, far more robust, able to grow far faster, able to travel out into space much sooner and faster, all made in factories out of stuff dug up in mines, and not at all based on biological cells, so that genetic engineering has little to offer them. If humans finally got to a new star under your plan, that star would have long since been well colonized by artificial life.
To which you say:
you might have missed a key part of my book that addressed this, since I wrote “AI—and not biological life—may in fact become the second Guardian sentience.”
But in my short word post I do summarize you as saying:
AIs might do as well as humans in a “guardian” role of making sure that life can spread through the universe.
Look, I’m not talking about AIs replacing humans in some limited oversight guardian role. I’m talking about vast fast artificial life quickly and vigorously replacing our familiar biological life en masse. Including replacing biological humans with artificial minds. Everywhere, not just in a few oversight roles. Except perhaps in a few limited zoos.
Can’t you even see a bit of conflict between that vision and your detailed plan to use genetic engineering to slowly change humans over 500 years so that they might arrive at another star in roughly a millennium? I don't see how we can debate if you can't even notice that I'm disagreeing with you.
