This is all to say (and sorry for the long rant!) she is advertising a false idea of academia and she will be disappointed in the future. She is also misleading a lot of younger people who might not be able to read for 10 hours a day (maybe because they have to .... work or do chores like most of us) but might have stronger analytical skills than her and still be put off by academia because of the framing people like Ruby present of this field. Rant over!
Absolutely.
What's even more frustrating is that she seems completely aware that putting that much extra work is completely unnecessary and unrealistic, but still engages in and encourages it. In one of her recent Q&As she mentioned she'd advise her younger self not to put that level of extra work into essays and exams as she fully recognises that it's not necessary for gaining the grades needed and likely didn't improve hers any. So she's self-aware enough to realise she's just going overboard, but still actively does it and promotes that unhealthy lifestyle.
In Ruby's case, devoting what seems like 12+ hours a day to studying isn't just wildly impractical, it clearly hasn't helped her in any way other than tangentially, with her studytube videos becoming popular. Devoting all her time to studying didn't help get her into her dream uni, her academic and critical skills are still highly questionable and her social life appeared non-existent even before the 'rona. Her one major success has been building a brand and a platform for herself, but clearly spending her entire waking life studying (and occasionally frolicking) hasn't sparked any inspiration for new video ideas or ways to grow and stay relevant.
I found it especially sad that she says being an author is her dream job and she wants to make a living as a writer. She mentions writing in her routine videos, but she only seems to spend a tiny amount of time on it compared to all the needless, timewasting "productivity" crap she does for uni. She doesn't need any of the academic busywork she does to achieve her goal of being an author, and if she were smarter, she'd realise she's been in a prime position to leverage her YouTube fame to kickstart a writing career and she's squandering it.
Publishing houses love giving contracts to YouTubers because it's a new writer that comes with a built-in fanbase and a tonne of easy sales (plus they have their own pre-built platform for publicity.) As evidenced by Sasha Alsberg, Christine Riccio, Zoella (and her ghostwriter,) Unjaded Jade, and so on, quality and talent isn't a concern, so long as they can slap a familiar "brand" name on a book and market it to young fans and achieve some crossover sales as well. I've no doubt if she put some small amount of effort in, she could use the powers of internet fame and get a legit book deal somewhere, even if it's at a smaller publisher. She could even document the process for some original (for her, at least) video content.
But why achieve your goals when you can read Lewis Carroll while brushing your teeth and wistfully daydreaming about living in the Victorian era, when you could churn your own butter, dance carefree through fields and die from consumption at the age of 25.
