Go find some Soviet space art, or mid century American “space age” stuff, or less dark forms of cyberpunk / cyber culture from the 80s and 90s. None of that is fascist yet all of it is popularly called “futurism.” I’ve even seen the term associated with solarpunk.
As popularly used it means more or less the idea of trying to use human intellect to build or create something fundamentally new, or roughly that. It’s not a precise term more of a vibe.
Mid century American and Soviet space art had transparent political purpose, as does solarpunk. Futurism is rarely if ever just "it's the future, and that's neat!". It comes with the inherently political baggage of "We got from where we are to the glorious future, by way of (ideology)". Star Trek is a great example of this.
