I think the Internet is having an impact in very diverse ways anchored around amplifying voice, from enabling what I like to refer to as micro-activism.

As much as innovation is important, I think we also need to just make stuff. If we look at Kenya, where I'm from, as an example, we are importing everything down to toothpicks.

I want my work at Google to have a long-term impact on the tech scene in Africa and to result in millions more Africans not just going online but having an amazing experience once they do. That's what drives me every single day when I get to work.

Press and Internet freedom correlate against economic and social success, GDP, innovation, number of patents filed, and educational attainment. The more freedom there is, the more information, the more choice, and ultimately, more power for each individual.

Understanding of natural language is what sometimes is called 'AI complete,' meaning if you can really do that, you can probably solve artificial intelligence.

Bitcoin's revolution: an impossible-to-counterfeit digital store of value that can be used as money, that has no sovereign, or central bank involved, that can be sent anywhere instantly at virtually no cost, is irresistible. Anyone who uses it is converted.

You have to have a big vision and take very small steps to get there. You have to be humble as you execute but visionary and gigantic in terms of your aspiration. In the Internet industry, it's not about grand innovation, it's about a lot of little innovations: every day, every week, every month, making something a little bit better.
