> artistic movements and styles are also some type of socio-political movement

Cyberpunk was social and political commentary from the start. Solarpunk is too, but feels less genuine. It feels like a corporate feel-good aesthetic designed for pharmaceutical television commercials hocking anti-depressants.

I've never seen much in the way of social or political commentary from steampunk. Steampunk is extremely kitsch. It looks cool, but there's not much more to it than looking cool and invoking pseudo-nostalgia for the 19th century. At best you get some weak commentary about 19th century colonialism and industrialization chewing people up, but mostly this genre is about glorifying the Victorian/Industrial style.
