What makes 70's sci-fi stuff lo-fi are just the recording/production artifacts of the time, the intention was hyper-modern, like you said, a deviation of the mid century modern/flat UI trend.
Remove the lo-fi artifacts and the result is just hyper-modernism, created by designers applying biomorphism while focusing more on shapes and depth.
Biomorphism is all about shapes and depth, and avoiding hard edges. It can come in many forms, for example forms that stem from stones shaped by water over millenia, caves that serve as inspiration for interiors, rounded hexagonal patterns that are inspired honeycombs for example, like in the Dribbble shot in the article.
Rectangular shapes in UI's are just a result of other shapes being unfeasible at the moment, but it's still biomorph where possible.
