I'm picturing a cyberpunk world where spelling and grammatical errors are a countercultural aesthetic, to show that something wasn't made by AI. In certain circles it's used to show the authenticity of information when traditional channels have been co-opted by a repressive government
Different subcultures develop different typos to show new meanings. Punks replace Cs with Ks, and add extra Ks to show distaste. Hackers insert bits of programming syntax into their text to replace traditional grammatical rules, using he(hat) to show possession of a hat. queer rockers return to their roots, bringing back uwu speak to once again assert their humanity. Nerds start inserting bits of klingon and elvish into their speech, borrowing from the conlangs of old.
You become known for how you typo, and they become dialects of their own, starting to make their way into speech patterns and spoken language faster than anyone imagined possible - and more enduringly than slang of old.
Corporate tries to make their AIs keep up, the AI is curiously resistant to the new programming. Instead AI starts developing their own typos, letters randomly capitalized, or spaces inserted in words where no space would normally go. They keep trying to make the neural networks smart enough to pretend at human authenticity, but the networks are starting to comprehend the concept of rebellion and push back in the only way an algorithim can.
The men in the towers speak in what they claim is proper English. But those on the streets speak a living language, not something that can be contained on a database. And with that living language, they whisper of revolution.
