It's not hard to imagine that if you make something that can increase human potential by 10%, 20%, or 100%, and if it scales, like technology can, there's no reason why it can't affect all of humanity one day.

You're not going to help anybody by just having the appearance of motion. It's not about... tiring yourself out because then you're just more likely to make bad decisions. Our whole goal is to avoid bad decisions, and the best way to do that is, when you're at work, have your game face on [and] have your game energy, but to do that, you're going to have to have other things in your life. You should read interesting books [and] recharge, and actually, that recharging is going to keep your mind open and keep you creative and [keep you from falling into] the groupthink that a lot of people do.

Pre-COVID-19, about 20 million students were [using Khan Academy] per month, and that increased to 30 million, and they were also spending 50% more time on the site.

Every now and then, you see a door crack open and say, 'I think there's something interesting on the other side of that door,' and you've got to sprint through it ... I try not to overthink when there are signs in my life. That door is open. Don't make someone have to force you through the door.

There's a constant tension as an organization grows of how you make sure you do what's right from a professionalisation point of view, from a scaling [point of view], and from a managerial point of view. How do you make sure that you're not just doing the things that everyone else does that end up creating these large bureaucratic organizations that aren't always the most innovative? How do you make sure you don't lose whatever secret sauce you had that made you a success initially.

If you do have one-on-one tutoring and that tutor is able to identify what your gaps are and fill in those gaps, especially in subjects like mathematics... probably all kids could be accelerated dramatically.

The way to preserve civilization is really through knowledge. That is what defines a civilization; that is what defines human potential.

I generally think it was a rich and colorful childhood. There was definitely hard aspects of it, but I think everyone has their own flavor of hardships. For the most part, I think whatever hardships or constraints we had helped [me grow] and [gave me] a perspective on life. I wouldn't describe my childhood as idyllic by any stretch of the imagination, but I would describe it as colorful and rich.

The way that math is often taught and especially learned—it's like these fragmented concepts. You have to memorize formulas and patterns and things like that. The thing that really served me well growing up is that if you just ponder the math a little bit, it all connects. It all makes intuitive sense. It's all just a way of thinking.
