Commenters here are getting confused. There's technocracy, the governance[1]. And Technocracy, the pseudo-cult movement[2]. They quickly evolved into different things with different ideologies. The article is mostly about the latter movement.
The Italian futurists went fascist. There were also Russian Cosmists who were IMO more interesting and didn’t seem fascist. They seemed more intellectual and heavily influenced science fiction. The Italian futurists were just on speed I think.
On the fringe right today there’s people who invoke Russian Cosmism and fascism, which I don’t get because historically they were distinct movements. But the fringe right is extremely incoherent. Fascism itself is also ideologically incoherent, and in that case it’s because fascism tends to be explicitly anti-rational.
