In defense of hard science fiction, it’s a meaningful category to talk about even if it’s not something you personally care about. People often want to weaken it but that just opens a door for a new category say “scientific science fiction” and we are back to square one.
Asking questions like what does AGI look like when they can’t just magically solve all issues can be fun. Hand waving the singularly as some religious event can also make interesting stories but so is considering how chaos theory limits what computation can actually achieve.
