"The inventors, creators — it's me, it's Mark [Zuckerberg], it's Kevin Systrom on Instagram, it's all of these people — understood this consciously. And we did it anyway."
I disagree that he's a sociopath (sociopath wouldn't disclose this information). I think he's a geek who got so caught up with what he was working on that he lost sight that it was very immoral until much later (and perhaps too late).
An important lesson for us all.
He talks about it because he feels guilt but knows he won't be punished.
He understood it was immoral. He still did it, because morality doesn't have the power to stop actions. Now he feels guilt for doing evil. But at least now he's ultra-rich and powerful. He understood what he was trying to achieve.
