Something I've been thinking about is how much fictional media conflates intelligence and knowledge. Like anyone who's a genius on tv or movies or comics (less so books, it feels like) will be able to do anything that's even vaguely related to whatever broad area they're a genius in (technology, medicine, etc), no matter their age, with no real consideration for... how they learned that. Being smart isn't a substitute for having studied the fundamental basics of a field. I think it's half deus ex genius for plot purposes and half just that the only way people know how to demonstrate intelligence in a character is having them know stuff, and it's easier to go broad because then you don't have to do as much research on the really technical parts of the one field they specialised in. One day I want to play a character who's really, really smart, but hasn't had the opportunity to get any real education beyond like basic literacy and numeracy, just for the challenge of trying to show the intelligence without the crutch of "oh yes, I can program and hack and do robotics and build a physical computer out of scavenged Radio Shack parts and hey look did you need this highly specific device that realistically probably requires that we first build several other machines and materials so we can actually build the parts, I'll have it for you in half an hour! My inventions can interface with the human body super easy because the brain isn't complicated at all! Who needs prototypes and lengthy testing periods? Not me! And I'm only 16!"
This may sound like a subtweet but it's really not, it's just that so much media has tech geniuses that it's bound to fit, like, half of them. S2g, tech geniuses and redhaired girls are the two absolute most over-used characteristics in fiction. I know I've played something like four of each, probably more.
