This is the thinking of someone on the timescales of a single life. If humanity persists another 1000 years on our current trajectory (US/world politics not withstanding), I think nothing is really a fantasy. Rather, it's all possible but maybe just not in our own lifetimes. But it is also terribly difficult for us to plan for tomorrow, let alone for a future where our descendants are at the helm.
replyI agree, it’s just a failure of imagination. Some folks correctly foresee not being able to continue what we’re doing now in the exact same way in some new context and conclude everything is impossible. Life isn’t this fickle, it’s adapted before and will adapt again. This is why great science fiction is so valuable, as some people are better at imagining new ways of being more than others, and can show the rest of us the possibilities.
