Facebook is quite entrenched and has a network effect. It’s hard to break into a network once it’s formed.

First, how do we give everyone a fair shot at opportunity and security in this new economy? Second, how do we make technology work for us, and not against us – especially when it comes to solving urgent challenges like climate change? Third, how do we keep America safe and lead the world without becoming its policeman?

Facebook was not originally created to be a company. It was built to accomplish a social mission – to make the world more open and connected.

To create a new standard, it takes something that’s not just a little bit different; it takes something that’s really new and really captures people’s imagination, and the Macintosh, of all the machines I’ve ever seen, is the only one that meets that standard.

Advertising works most effectively when it’s in line with what people are already trying to do. And people are trying to communicate in a certain way on Facebook – they share information with their friends, they learn about what their friends are doing – so there’s really a whole new opportunity for a new type of advertising model within that.

The truth of Moore’s law has made remarkable things possible. On the software side, I think natural user interfaces in all their forms are equally significant.

Technology has allowed people to make records really cheap. You can make a record on a laptop.

I’m not a futurist.

My opinion is it’s a bridge too far to go to fully autonomous cars.

I’m trying my best to keep up with all this new technology, and I surround myself with all these wonderful people that are in the know and kind of help me out with all that.

There’s no other company that could make a MacBook Air and the reason is that not only do we control the hardware, but we control the operating system. And it is the intimate interaction between the operating system and the hardware that allows us to do that. There is no intimate interaction between Windows and a Dell notebook.

I don’t write letters anymore.

We just think that there are all these different ways that people want to share, and that compressing them all into a single blue app is not the right format of the future.

This is a fantastic time to be entering the business world, because business is going to change more in the next 10 years than it has in the last 50.

What really motivates people at Facebook is building something that’s worthwhile, that they’re going to be proud to show to friends and family.

Health is certainly extremely important, and we’ve done a number of things at Facebook to help improve global health and work in that area, and I am excited to do more there, too. But the reality is that it’s not an either-or. People need to be healthy and be able to have the Internet as a backbone to connect them to the whole economy.

When the PC was launched, people knew it was important.

I tweet in the morning and the evening. To write 12 hours a day, there is a moment when you’re really tired. It’s my relaxing time.

People want to act like they know celebrities. They want to see pictures. They want to know where you’re going. They want to hear you talk about your family.

I was told that someone on Facebook said something ‚horrible‘ about me. Who cares? At least they’re watching the show.

Science in the modern world has many uses; its chief use, however, is to provide long words to cover the errors of the rich.

You pick up some fans and a handful of haters along the way.

I’m never going to go to Mars, but I’ve helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

What I think we need to do is pass a bill that says number one, you own your data. Number two, you can license it to Facebook but the licensing has to be knowing, it has to be willful.

I’m sorry, it’s true. Having children really changes your view on these things. We’re born, we live for a brief instant, and we die. It’s been happening for a long time. Technology is not changing it much – if at all.

In general, we’re a social network. I prefer that because I think it is focused on the people part of it – as opposed to some people call it social media, which I think focuses more on the content.

Now everyone takes it for granted that you can look up movie reviews, track locations, and order stuff online. I wish there was a way we could take it away from people for a day so they could remember what it was like without it.

Men have become the tools of their tools.

I had wanted a tape recorder since I was tiny. I thought it was a magic thing. I never got one until just before I went to art school.

We must ensure that technology is accessible, affordable, and adds value.

If there were camera phones back in the day, the biggest athletes in the world would have had a lot of explaining to do.

We could definitely make a flying car – but that’s not the hard part. The hard part is, how do you make a flying car that’s super safe and quiet? Because if it’s a howler, you’re going to make people very unhappy.

We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology.

When you say ‚follow me on Twitter,‘ and you get 10 million people to follow you – you just leveraged your influence to add value to an app that you have no ownership in.

How do people relate to movies now, when they’re on portable devices or streaming them? It’s not as much about going to the movies. That experience has changed.

The wealth of information now available at the click of a finger amazes me.

Now the playbook is we build AI tools to go find these fake accounts, find coordinated networks of inauthentic activity, and take them down; we make it much harder for anyone to advertise in ways that they shouldn’t be.

The reason we wouldn’t make a seven-inch tablet isn’t because we don’t want to hit a price point, it’s because we don’t think you can make a great tablet with a seven-inch screen.

I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We’ve created life in our own image.

The world has today 546 nuclear plants generating electricity. Their experience is being continuously researched, and feedback should be provided to all. Nuclear scientists have to interact with the people of the nation, and academic institutions continuously update nuclear power generation technology and safety.

SPAM is taking e-mail, which is a wonderful tool, and exploiting the idea that it’s very inexpensive to send mail.

Ever since I started to get recognition I’ve picked out certain fans and reverse-stalked them.

Silicon Valley has some of the smartest engineers and technology business people in the world.

We no longer think of chairs as technology; we just think of them as chairs. But there was a time when we hadn’t worked out how many legs chairs should have, how tall they should be, and they would often ‚crash‘ when we tried to use them.

Microsoft Research has a thing called the Sense Cam that, as you walk around, it’s taking photos all the time. And the software will filter and find the ones that are interesting without having to think, ‚Let’s get out the camera and get that shot.‘ You just have that, and software helps you pick what you want.

I think every age lives in a blend of technology so there’s always older ones mixed in with newer ones, and when the new technology goes down, the immediate fallback position is either that technology just before that or one several technologies back.

We’re already cyborgs. Your phone and your computer are extensions of you, but the interface is through finger movements or speech, which are very slow.

You can always think of something like the Xbox 360 as a super set-top box that can do everything the set-top box does, but then have the graphics to do the games as well.

People are very reluctant to talk about their private lives but then you go to the internet and they’re much more open.

Certainly there’s a phenomenon around open source. You know free software will be a vibrant area. There will be a lot of neat things that get done there.

The real story of Facebook is just that we’ve worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded.

The biggest mistake we made as a company was betting too much on HTML5.

It is definitely true that the fundamental enabling technology for electric cars is lithium-ion as a cell chemistry technology. In the absence of that, I don’t think it’s possible to make an electric car that is competitive with a gasoline car.

What we want to do is make a leapfrog product that is way smarter than any mobile device has ever been, and super-easy to use. This is what iPhone is. OK? So, we’re going to reinvent the phone.

Eventually we’ll be able to sequence the human genome and replicate how nature did intelligence in a carbon-based system.

People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people – and that social norm is just something that has evolved over time.

I got my first computer in the 6th grade or so. As soon as I got it, I was interested in finding out how it worked and how the programs worked and then figuring out how to write programs at just deeper and deeper levels within the system.

We’re a community of a billion-plus people, and the best-selling phones – apart from the iPhone – can sell 10, 20 million. If we did build a phone, we’d only reach 1 or 2 percent of our users. That doesn’t do anything awesome for us. We wanted to turn as many phones as possible into ‚Facebook phones.‘ That’s what Facebook Home is.

Harnessing steam power required many innovations, as William Rosen chronicles in the book ‚The Most Powerful Idea in the World.‘

Netscape was able to get the government working on its behalf.

The main Facebook usage is so big. About 20 percent of the time people spend on their phone is on Facebook.
