Edward Snowden is often depicted as a genius. After reading this book, I don't believe that to be true.
Geniuses are "above human beings", whereas Snowden depicts himself as being extra-human. And a smart one on top of that.

Having grown up at the same time as him, and followed a career in technology as well, this biography talked even more to me, as I could really identity to him. What he says is entirely true, extremely well written very moving.
