This collection put out by ASU’s Center for Science & the Imagination looks partly good: Hieroglyph: Stories & Visions for a Better Future
Judging by the blurbs, it’s a mix of hard SF by Benford and Stephenson, medium SF by Landis, Brin, and Doctorow, soft SF by some (to me) unknowns, and “pink” SF by io9.com SJWs Anders and Newitz. You know what you’re going to get from the five big-name authors, and that it likely will be worthwhile, but you also know what you’re going to get from the two SJWs, and that it likely won’t.
That leaves the unknowns. Ordinarily I would be intrigued enough by the big-name authors to give the others a try, but the presence of Anders and Newitz signals to me that the unknowns might turn out to be little more than half-competent leftist groupthink peddlers. I’d hate to shell out $10.99 for an e-book (!) only to end up feeling suckered into buying a bunch of preachy social justice/environmentalist propaganda.
(Aside: the site design there is terrible. If visitors have to apply conscious effort to sort out the structure and content from dog’s breakfast of distracting graphical overdesign, you’re doing it wrong.)
