Does Bad Blood cover the tech aspects of Theranos? My impression was that it was more about the psychological and legal stuff.

Edit: ... which obviously doesn't make the book any less interesting.

It does indeed. The question you are asking leads me to believe you haven't read it. As a favor to the thread I will make this plain: drop everything else you're reading long-form and buy a copy of _Bad Blood_; it is fantastic. I didn't give a shit about Theranos. Until I got a couple pages into Carreyrou's book, that is.

Haven't read it. It's been sitting on a pile somewhere. Time to reprioritize!

There is at least one "holy shit" moment in every single chapter in that book.
