They could not go back to biology for the same reasons that we cannot go
back to Stone Age life (without conceding the defeat of human civilization
in toto).
Furthermore, at present rates of environmental destruction, "they" (who
remain fictional) will have no biosphere in which to return. In addition,
the motives for trashing biology do not appear conducive to biological
resurrection.
This does not constitute a gap to bridge, or if it does, then traffic flows one way only. For example, having reached adulthood, the butterfly cannot go back to the larval stage. To conjecture that the hypothetical "they" will have the necessary skills and technology to rebuild a dead Earth begs the question: Why would they if they didn't need to? And if they needed to, that would indicate an unforeseen dependence which shows the flaw in their desire to become non-biological.
Experimenters called the only "backup" Earth ever tried "Biosphere II" and although the enthusiasts involved learned much from their endeavor, the greatest thing they learned relates to the incredible ignorance humans still have concerning ecological systems and how they work. Science has not come close to devising methods to simulate the complexity of large scale living ecosystems.
The notion that, in the words of Wilson, "our species exists apart from the natural world and holds dominion over it. We are exempt from the iron laws of ecology that bind other species. Few limits on human expansion exist that our special status and ingenuity cannot overcome. We have been set free to modify Earth's surface to create a world better than the one our ancestors knew" he calls "exemptionalism."
He continues:
"For the committed exemptionalist, Homo sapiens has in effect become a new
species, which I will now provide with a new name, Homo proteus, or
'shapechanger man.' In the taxonomic classification of Earth's creatures,
the diagnosis of hypothetical Homo proteus is the following:
"Cultural. Indeterminately flexible, with vast potential. Wired and information-driven. Can travel almost anywhere, adapt to any environment. Restless, getting crowded. Thinking about the colonization of space. Regrets the current loss of Nature and all those vanishing species, but it's the price of progress and has little to do with our future anyway.
"Now here is the naturalistic, and I believe correct, diagnosis of old Homo sapiens, our familiar 'wise man':
"Cultural. With Indeterminate intellectual potential but biologically constrained. Basically a primate species in body and emotional repertory (member of the Order Primates, Infraorder Cattarrhini, Family Hominidae). Huge compared to other animals, parvihirsute, bipedal, porous, squishy, composed mostly of water. Runs on millions of coordinated delicate biochemical reactions. Easily shut down by trace toxins and transit of pea-sized projectiles. Short-lived, emotionally fragile. Dependent in body and mind on other earth-bound organisms. Colonization of space impossible without massive supply lines. Starting to regret deeply the loss of Nature and all those other species." <end quote>

Yes, I think you've located the point at which something has gone wrong: The
use of the word "always." I should have written: Something _can_ go wrong.
Passivity indeed constitutes a huge problem. Far too few people work to
reverse the damage done to the biosphere. Far too few work toward reversing
the destructive trend of overpopulation. Far too many shirk the
responsibility to live up to human values of compassion, comprehension, and
community, choosing instead to live in a fantasyland of denial.
Consilience means to bring all "*their*" systems together, to unify
knowledge, and to bring consistency to all the sciences, and especially to
sort out which systems have validity and which do not.

Excuse my harshness, but the situation in the "_real_ real world" as Wilson puts it, requires the application of severe and intense measures to solve the problems of today and tomorrow. None of this in any way conflicts with the reality of extropy as it seeks to build more complex habitats for more sophisticated life forms. Indeed, extropy demands that humans put their ecological house in order so that we don't plunge ourselves into another Dark Age. To the extent that Homo sapiens remains passive about conservation, it thereby makes itself entropic.
The way I see it, extropy means the movement toward more powerful ways to enrich and expand life. The first and best use of extropian tools involves cleaning up the mess humanity has made. The Sorcerer's Apprentice will not remain an apprentice, we may hope. But if the Scientist does not remain true to science, humanity has not much for which to hope.
