So my understanding is that uwu/UwU originates as a kaomoji, think (^.^) and (O.O) etc. Using the 'w' character to render the mouth starts as a furry thing or a general projection of human expression onto common animals like cats or dogs. (You'll see the omega symbol used in examples as well.)
Over the last 20-30 years or so of online interaction etc. kaomoji start to gain a sort of cringe notoriety alongside RP chatting, culminating in a few catalysing memes/copypastas.
Eventually "owo" and "uwu" start being read aloud/vocalised, similar to how people starting saying "lol" out loud, and this is associated I guess with a cutesy sort of image, though that image is often corrupted or subverted- for example e-girls, who co-opt a lot from of gaming and anime subcultures, lean into the uwu of it all.
Yes. Think about what it is plagiarising. Datasets are biased; this is like statistics/ML 101.
You can just say the country, and also, this doesn't really make any sense. Am I to infer that, if things weren't political, people would vote (a famously political action) for independents?
I'm pretty sure there's a lot more wrong with LLMs than just plagiarism.
I'm not 100% sure what you mean here.
