A Smorgasbord of Sci-Fi Cliches

If you want to conjure an original science-fiction story, try to avoid or subvert the following things, which have been done time and time again:

A group or race of artificial intelligence beings become so much smarter than humans and try to rebel against their creators or kill off humanity.
AIs (Artificial Intelligences) or robots turn evil suddenly and without reason.
Aliens that are anthropomorphic or too humanoid / Earth-organism-like. Planets have many strange and differing conditions which would influence how its people and animals evolved. For example, a planet constructed of gas and clouds would likely have beings whose bodies are made of air. A planet with a high amount of gravity would give birth to a race of unfortunate, flat-topped, squat beings like walking rock-tables. Yes.
Parallel universes. Philip Pullman scored a hat trick using this idea. I’m struggling to think how someone could top that.
Chemicals come in an array of unrealistic colours and all of them bubble, plop, hiss, or eat holes in the table / carpet when spilled. In actuality, chemicals tend to be white, off-white, or transparent (like those catalogues of paint colours, you know, the ones you look at when you’re desperately trying to decide whether to paint the lounge button-mushroom shade (white) or skull-and-crossbones shade (um… white).
Electricity is described or shown as bolts of blue, white, or violet lightning.
Anyone can hack into a computer even if they know little about computers. In reality, this doesn’t happen. Computers are eye-bogglingly, insanity-inducingly difficult to pry into because of the algorithms and what-have-you. And it would take someone months, if not years. Not five minutes or half an hour.
At some point, a spaceship will suddenly suffer an oxygen leak. Which I suppose is the literal definition of a Flying Fart in Space, or FFS. TTFN.
Radioactivity or radioactive waste / gamma rays give characters cool mutations and superpowers (instead of melting them to death or giving them cancer.)
There’s a well-hidden traitor or mole in the protagonist’s loyal group of friends (Among Us, anyone?)
Aliens are terribly interested in Earth and either want to help us or kill us. Why would a race of beings clever enough to invent physical travel to far-off planets be at all scintillated by the likes of us, a race of anthropes who can’t even maintain an equal and just society without galumphing off to war every five seconds?
There’s always an option to manually override a system (like a bomb, or something like a bomb controlled by a computer system.)
Time travellers never face difficulties with people in different eras not understanding their dialects, accents, slang, and other use of language, and vice versa.
Time travellers are immune to any unusual diseases that would be present in the past or future.
Time travellers survive the massive shock that going to a different time would induce with ease. Why? And how? Oh, for that kind of resilience on a Monday morning!
It’s possible to travel faster than light and everybody does it (and there’s not much context or explanation as to how it works.) In reality, this is impossible, but travelling close to the speed of light is possible, and it would do odd things to time… hint, hint, hint…
Everyone can hear in space. Despite the fact that there isn’t any air in space, which means that sound waves can’t travel to the ear. If you think about it, space operas are basically silent movies with audible subtitles and canned laughter.
To get around having to use scientific theories, authors use techie-sounding jargon when giving convenient machines names, or when the characters are in a tight spot and have to use a “baronullifyingprotobackstabber” for example, (like an umbrella?) or a “plosiveleveragecarboninducer” (like a toaster?) OK, bad examples, but you get the general idea.
People teleport to different countries or areas instead of walking (and in some cases, this causes a rise in obesity levels.)
Aliens have mind control / telepathy / telekinesis, or humans have evolved to have those skills.
After Earth develops space travel, different planets join together into a universal EU or League of Nations, then one planet decides to rebel and there’s an interplanetary war. There’s enough war on this planet, why would you wish it on other ones?
Dystopian worlds where the climate has been destroyed by nuclear weaponry or another calamity, and humans are living like cavemen.
Evil twins (whether the human variety or the planetary / dimensional variety.)
