Which book changed the way you think, and what did it change?

I think of another book that I read – what was it called? – Night Train to Lisbon. I wouldn’t say it’s in that same category, but sometimes there was just a line in a book that changed my life in some way, and it came at a critical juncture. The line was, “Given that there is so much in all of us, what happens to the rest?”

the thesis in the book is that computers need to understand human emotions just the way people do. I read the book and I was just fascinated by this idea. I made that my research topic and it became my obsession and it just really changed the trajectory of my life.

That really crystallized for me what some really passionate founders who could write some code could do to change things, and this gave me the confidence to say, “You know what? They can do this. We can definitely do this.” ... So without a doubt, Reddit would not exist if it weren’t for Masters of Doom.
