A lot of the sci-fi of the era was based off of the assumption that corporate power would rise to rival that of governments. That runaway capitalism would birth "high-tech low-life" as the state of society at large. Yes, the stars are aligning between the interests of the powerful in the present, and the future postulated in those stories; those stories were made on the basis of human nature and self-reflections on the contemporary. They are being proven right because they assumed plausible futures with likely outcomes. Want a solar punk world? We have to buck the trend and disrupt the trajectory we're on now. Will we have pivotal moment like that of Americana circa 1929, or slide further in a hellscape? I know what future I want but I don't know if we're going to get it.
