I think it has more of the stories to tell rather than the setting. When I hear the word “cyber-punk,” it’s a mental short cut for what the world is going to look like.
That setting though, is not the story. So I’d push back a bit on the title. We could say, “Why does High Fantasy or Grimdark or Steampunk or [insert Genre Fiction of Your Choice] refuse to move on?”
The novella Monster Slayer is essentially an action movie taking place (Die Hard…on the ocean…IN THE FUTURE) in the cyber punk setting. It’s a story that feels WAY DIFFERENT than the novella Monitor. Both are (obviously) cyberpunk, yet both feel like they are exploring vastly different parts of that future.
