All you need to ask is “What if?” Sometimes it can be a serious question (“What if AI became sentient?”) and sometimes its delightfully unserious (“What if the entire crew of a ship except the janitors got taken out?”).

Science fiction is genre chocolate — it goes great with a lot of other flavors, and by flavors I mean pretty much every single one of our other favorite genres.
