I have never understood the need for SciFi to have:
- Swords – we don’t use them these days, why would we suddenly start?
- Revolvers – with blasters and swords, why is there a need for a firearm that requires oxygen?
- Magic – force, farce – if the plot needs it – taa daaa. We temporarily make our MC a god and then quickly demote him…
I really feel strongly that we can write SciFi, that is – Science Fiction, which will be compelling without resorting to writing a fantasy or western novel. Clarke’s work had no swords, no gods, no guns. His violence was passive – Dave will die if the door stays closed. Seals and filters and constant repair is what really happens. Endless cycles of repair, grease, action, repair.
