@Slaybutter is right, she does put down other content creators and uses her education as a weapon to do so. I think it entrenches the attitude that you have to have a degree to have a correct opinion, which I think is wrong.

They have experience of working with hundreds of clients that I'd never hope to replicate with all my textbooks about protein structure analysis... Horses for courses.
