The trope I hate the most is the "cybernetics eat your soul". The notion that if you replace a part of you with non-organic analog, you are now less than human. It INFURIATES me how luddistic it is. People advocating "YES you would totally turn into a heartless psychopath!" for some reason always abruptly go quiet when I mention people with advanced prosthetics, or people that have actual artificial hearts. Why did you stop saying how they traded their humanity away? Guess those don't count because they exist in real life, yeah?! Get out of here before I punch you in your technophobic face.
Another trope that I hate with passion, for very similar reasons, is the "AI's will ALWAYS try to destroy their creators and\or be hating all organic life and\or will lack any sort of empathy or emotion, because they're just naturally evil that way and We Should Not Play Godsâ˘"

I kinda burned out on this one after I saw plants with boobs. Used to annoy me but now I just sigh and unzi
Absolute majority of the spacecrafts in our history were completely fine flying without any human crew whatsoever (and Buran spacecraft was able to take off, make it to orbit, and then land completely without any human involvement. That was achieved in the 80s. By the soviets). Space is a LUDICROUSLY large and empty place. Sleeping during the flight is actually the realistic option IMO. Or else what are you gonna do on a flight that takes eight months to reach the destination, except to spit into the ceiling and slowly going mad from boredom?
Yeah, but give 'em a puppy seal, and they ALL just melt away. It's easier to empathize with non-human things precisely because they're non-human. We don't have centuries long bad history, stereotypes and prejudices about roombas. So we give them names, dress them in maid outfits and pretend that we feeding them by brushing the crumbs off the table.
I always found this reasoning nonsensical, people are perfectly capable of empathizing with all sorts of things and nonhuman characters like Wally, R2D2, Garrus or Christopher Johnson from District 9 - hell, one game makes you empathize with a colored cube! "Then they won't be able to care about the character" is an excuse for lazyness, and an extremely weak one at that.
