If you count E-mail, I’m on the Internet all day, every day.

Every aspect of human technology has a dark side, including the bow and arrow.

Drones overall will be more impactful than I think people recognize, in positive ways to help society.

If we’re trying to build a world-class News Feed and a world-class messaging product and a world-class search product and a world-class ad system, and invent virtual reality and build drones, I can’t write every line of code. I can’t write any lines of code.

People everywhere love Windows.

If you think back to the beginning of cell phones, laptops or really any new technology, it’s always expensive.

E-governance is easy governance, effective governance, and also economic governance. E-governance paves the way for good governance.

One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.

The X is an amazing car, but we kind of got carried away with the art and technology. Obviously, you want great art. You want great technology. But we did get a little distracted from our mission, which was to advance the cause of electric vehicles. And it probably delayed us a little bit with the Model 3 as well.

Science may have found a cure for most evils; but it has found no remedy for the worst of them all – the apathy of human beings.

I don’t write letters anymore.

The tablet is not mainstream. Reading off the screen is not mainstream.

I do think there is a lot of potential if you have a compelling product and people are willing to pay a premium for that. I think that is what Apple has shown. You can buy a much cheaper cell phone or laptop, but Apple’s product is so much better than the alternative, and people are willing to pay that premium.

Land on Mars, a round-trip ticket – half a million dollars. It can be done.

There happen to be a lot of people around who spent an hour on the Internet and think they know a lot of physics, but it doesn’t work like that… There’s a reason there are graduate schools in these departments.

Any sufficiently advanced technology is indistinguishable from magic.

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.

If Al Gore invented the Internet, I invented spell check.

Study hard so that you can master technology, which allows us to master nature.

I think television has had a vast, unbelievable impact on us.

You can think of the entire Internet as a place where ideas embodied in cyberspace are having a war, and it’s not much different than the war of gods in heaven, which has been taking place since there’s been human beings.

In the twenty-first century, the robot will take the place which slave labor occupied in ancient civilization.

I’m a Silicon Valley guy. I just think people from Silicon Valley can do anything.

We polled Tesla owners, do you want autopilot disabled or not. Not one person wanted it disabled. That’s pretty telling.

We wind a simple ring of iron with coils; we establish the connections to the generator, and with wonder and delight we note the effects of strange forces which we bring into play, which allow us to transform, to transmit and direct energy at will.

The thing that’s been really surprising about the evolution of Facebook is – I think then, and I think now – that if we didn’t do this, someone else would have done it.

For a highly motivated learner, it’s not like knowledge is secret and somehow the Internet made it not secret. It just made knowledge easy to find. If you’re a motivated enough learner, books are pretty good.

The over-all point is that new technology will not necessarily replace old technology, but it will date it. By definition. Eventually, it will replace it. But it’s like people who had black-and-white TVs when color came out. They eventually decided whether or not the new technology was worth the investment.

In ‚Changeling,‘ I tried to show something you’d never see nowadays – a kid sitting and looking at the radio. Just sitting in front of the radio and listening. Your mind does the rest.

Tesla is here to stay and keep fighting for the electric car revolution.

Man is a tool-using animal. Without tools he is nothing, with tools he is all.

The Internet, man, is a beautiful thing.

It’s not a faith in technology. It’s faith in people.

Microsoft is not about greed. It’s about innovation and fairness.

It is not, of course, complete yet – but some sentences were understood this afternoon… I feel that I have at last struck the solution of a great problem – and the day is coming when telegraph wires will be laid onto houses just like water or gas – and friends converse with each other without leaving home.

Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.

For NASA, space is still a high priority.

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.

For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

I get asked a lot why Apple’s customers are so loyal. It’s not because they belong to the Church of Mac! That’s ridiculous.

Ever since Newton, we’ve done science by taking things apart to see how they work. What the computer enables us to do is to put things together to see how they work: we’re now synthesized rather than analysed. I find one of the most enthralling aspects of computers is limitless communication.

The desktop metaphor was invented because one, you were a stand-alone device, and two, you had to manage your own storage. That’s a very big thing in a desktop world. And that may go away. You may not have to manage your own storage. You may not store much before too long.

We have too many cellphones. We’ve got too many internets. We have got to get rid of those machines. We have too many machines now.

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

I’m a great believer that any tool that enhances communication has profound effects in terms of how people can learn from each other, and how they can achieve the kind of freedoms that they’re interested in.

The Internet has compromised the quality of debate.

It is true that SpaceX is partially a government contractor, but it would be unfair to say that SpaceX is entirely a government contractor.

One of my big regrets is that Facebook hasn’t had a major chance to shape the mobile operating system ecosystem.

It’s a juicy thing to say we’re building a phone, which is why people want to write about it. But it’s so clearly the wrong strategy for us.

If Jesus were here today, he wouldn’t be riding around on a donkey. He’d be taking a plane, he’d be using the media.

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.

If you go back a few hundred years, what we take for granted today would seem like magic – being able to talk to people over long distances, to transmit images, flying, accessing vast amounts of data like an oracle. These are all things that would have been considered magic a few hundred years ago.

I’m not a man deeply interested in technology. It eludes me.

Move fast with stable infrastructure.

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

I’ll always stay connected with Apple. I hope that throughout my life I’ll sort of have the thread of my life and the thread of Apple weave in and out of each other, like a tapestry. There may be a few years when I’m not there, but I’ll always come back.

At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people’s capacity to build and maintain relationships.

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

The usual method of finding a little dongly thing that actually matches a gizmo I want to use is to go and buy another one, at a price that can physically drive the air from your body.

People don’t want lots and lots of single purpose devices. They do not want to have to learn how to set up something for photos, another thing for music, another thing for video.

It’s like the Wild West, the Internet. There are no rules.
