Even so, I want to say explicitly that the idea that we should allow geniuses to abuse us and harass us because they are geniuses is dangerous and misguided nonsense. Being smart is not an excuse to behave poorly. With rare exception, producing something great for the world, or believing you are working on something great, is not justification for hurting others or not taking into consideration their needs or feelings, especially when they are working for you to try to help you.
I also think that your reduction of 100-hour-minimum work weeks, no free time, emotional manipulation to prevent reporting, and frequent unnecessary cruelty disguised as "advice" or "help" to "unkind comments" is absurd. If people chose this lifestyle, knowing what they were getting into, that's one thing (and even then, it would still be dubious to demand it in the first place) - but clearly the author and their peers were mislead and manipulated into it.
Finally, what is illegal and what is immoral are not the same thing, and we can and should hold people, as a society, to a higher standard than "guess they didn't break the law" when we put them in positions of power over other people.
Edited to add: I had the pleasure of working as an undergrad with several professors and PHD students in a research capacity. Some of these people, I would absolutely consider "geniuses" in terms of both intellect and achievements. I still speak with many of them, and consider some of them good friends. I never, not once, observed or heard of people being treated in the ways described in this article (nor was I myself), despite the relatively prestigious people I worked with and their relatively prestigious work. It is not that way everywhere.
