I think you're giving her too much benefit of doubt. Just a few days ago, she showed us a piece of her writing, which she thought was publishable quality- it had basic PUNCTUATION mistakes. Forget about grammar, tone, style, etc. because one could argue those are subjective. But her writing is just objectively horrendous, no matter how you look at it.
And I've watched 90% of her videos for years, not ONCE has she had an interesting or original "hot take" on anything. She just (inaccurately) regurgitates historical facts, or directly plagiarizes other people (just see that Van Gogh reference in the Paris video). There's too much evidence she ISN'T deserving of a First.
She's the only person I know whose imposter syndrome is actually justified. I'm hoping she goes for a Master's, it'll humble her a bit at least.
