Best description of Hard Science Fiction I've ever heard!
My back burner novel/novella prompts include:
The gods have died, as they do every few centuries. Mortals compete in various ways to take a place for themselves in the new pantheon. Thinking something along the lines of the Hunger games meets Olympic games, except not dystopian and participants don't necessarily die, they may become demi-gods, religious leaders, or as a runner up prize the counter deity (the Satan to the new god).
A therapist for sentient AI tries to help a robot that is having the existential crises "Do I really like my programmer or has the programmer programmed me to like them?" Started this once as an exercise to help improve my dialogue, it was a dialogue only piece.
There's a ban in the galaxy on developing hybrid cybernetic technology that relies on living tissue as a component of the robotic organism. A lab on a rather inhospitable planet is attempting to develop this technology, and is being investigated by officials of the galactic government. It's discovered that young women have been being used in experiments because the womb is the perfect place to power the computer portion of the cyborg. The hero/heroine falls for one of the cyborgs maybe?
A great American cowboy western, except instead of cattle or maybe horses they have dragons.
Middle aged mom of 3 keels over with a cerebral aneurysm. She awakens in an alternate reality created by changing one thing in her past; she went to the battle of the bands in high school and her band won, which launched her into stardom and the rock and roll lifestyle.
The apocalypse has happened except it's not war, plague, or global warming which has caused it, rather the addiction to technology has resulted in such massive dysfunction in humanity that survival is no longer tenable. OR Post apocalypse except all electricity/electronics are now gone, everyone trying to re-learn skills once given over to machines. Taking into consideration how that impacts other things in life like finance: most commerce is now electric or web-based. Maybe call it Farmageddon?
Write a serial about the nondescript tavern that seems to be the opening setting for every D&D campaign ever, told from the viewpoint of the inn-keeper.
