Steampunk as a genre is dead. In fact, it was never alive to begin with. When Gibson and Sterling wrote The Difference Engine back in 1990 with steampunk aesthetic, drawing influence from the earliest days of sci-fi, it was to put cyberpunk tropes out of context and to show they're not new at all and since then we have post-cyberpunk. It was a joke that not a lot of people understood and in the end only the aesthetics of steampunk survived. Sadly, that seems to be enough nowadays.
