Good futurists to me are ones who are aware of and consider workable solutions to the current impending disasters of our time.
So, consideration of how human and other species can not be wiped out by industrial ecosystem destruction, mass extinctions and climate changes. And not overly-optimistic “GMO food will solve everything” notions.
And, consideration of how economic ideas can transform so that the future is not a corporate-dominated hell.
And the futurists I think are good do not have severely incorrect ideas about what artificial intelligence can possibly do and what consciousness is, so they are not thinking that biological humans will be able to become part of a computer program (e.g. “the singularity” or be an AI in an android).
I think good futurists also should understand the psychological problems with modern society, and have some notion that mental health and peoples’ conception of healthy human development need to progress.
