I think you are right. I was looking at it through the lens of potential “now do you have any questions” type questions, like in an interview, as some of the other comments here have mentioned. But that isn’t mentioned in the article. They are probably just for introspection that sort of question makes more sense.
(OP) Correct. The first couple sentences stress this, the questions are just mini thought experiments. Not an assertion of anything. Have fun with them, don't belabor them. If all or none of the questions aren't your cup of tea, who cares.
The thought experiment regarding diversity challenges the (typically) inconsistent implementation of it where it's more like a candy story where you pick what you like (or deem socially acceptable) and dismiss or even discourage anything else. That's not true diversity. It's equity.
Similarly, as you suggest that representation matters, and if you'd consistently believe that, then we should immediately reallocate a huge amount of women to do the shittiest, riskiest, lowest paid jobs that men currently do. Likewise, we should immediately deploy a huge amount of men in female-dominated professions, like HR, psychology, the like.
I bet quite a few would now lose their appetite for "representation". We might as well just stop pretending and admit that we have no principles or beliefs, we just want whatever is best for us or our "group", whatever that means.
