I know folks with it as well but they are not 1000x smarter than the rest of us. My point is that having her little apartment stacked with books doesn't support her being ultra-smart, just messy and introverted. If she really is orders of magnitude smarter than the rest of us then keeping books around is kinda like having a bunch of pizza boxes at your place after you ate the pizza. She presumably absorbed the info from the book and since they were written by folks 1000x DUMBER than she is, so other than few insights the books are mostly trash. Does she need books with charts and tables of info? No, she is ONE THOUSAND TIMES SMARTER and has a photographic memory, it's literally her superpower (well, other than the regeneration they all seem to have) so she functions at the level of a supercomputer plus she also has awesome empathy.
Anyway, more my complaint with the set dresser than the character as I've only seen ep1 so far. I just think they could have set her up much more impressively had they just thought through her power and how she might act, then present that on screen. They could have had her translating ancient scrolls or comparing books in 4 different languages, rather than casually reading a book, slowly, while on the toilet of whatever.
At least she didn't beat an AI in chess* though
