I'm afraid I felt that the spaced repetition questions on quantum country were a complete waste of time. There I was struggling (a lot!) with trying to work out how on Earth to think about C^2 (the space of 2-tuples of complex numbers, which you might semi-naively think of as 4-dimensional but that's probably a terrible mistake, but anyway that's not really germane to the point here) and the spaced repetition questions were asking me totally superficial questions, of the sort you might expect to be given to a 13 year old. I couldn't help feeling that this was likely to be a manifestation of the common desire nowadays to make things "inclusive". I would love for things to be inclusive, but we mustn't let inclusiveness be correlated with dumbing down; that will in the end turn out to be a toxic correlation. And there is a limit to how inclusive you can be about complex vector spaces and their use in modeling information in such a way as to facilitate non-classical computing.
