I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better.

The United States is definitely ahead in culture of innovation. If someone wants to accomplish great things, there is no better place than the U.S.

I feel very strongly that SpaceX would not have been able to get started, nor would we have made the progress that we have, without the help of NASA.

I was born in Africa. I came to California because it's really where new technologies can be brought to fruition, and I don't see a viable competitor.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

Obviously Tesla is about helping solve the consumption of energy in a sustainable manner, but you need the production of energy in a sustainable manner.

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.

People work better when they know what the goal is and why. It is important that people look forward to coming to work in the morning and enjoy working.

Even if producing CO2 was good for the environment, given that we're going to run out of hydrocarbons, we need to find some sustainable means of operating.

It is theoretically possible to warp spacetime itself, so you're not actually moving faster than the speed of light, but it's actually space that's moving.

The U.S. automotive industry has been selling cars the same way for over 100 years, and there are many laws in place to govern exactly how that is to be accomplished.

I've actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don't mean hybrid, I mean fully electric.

The path to the CEO's office should not be through the CFO's office, and it should not be through the marketing department. It needs to be through engineering and design.

SpaceX has the potential of saving the U.S. government $1 billion a year. We are opposed to creating an entrenched monopoly with no realistic means for anyone to compete.

There's nothing - I've bought everything I want. I don't like yachts or anything; you know, I'm not a yacht person, and I've got pretty much the nicest plane I'd want to have.

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.

I think most of the important stuff on the Internet has been built. There will be continued innovation, for sure, but the great problems of the Internet have essentially been solved.

The problem with car dealerships is you've already decided what you want to buy before you even go there, and you're really just going there to talk through some annoying negotiation.

Government isn't that good at rapid advancement of technology. It tends to be better at funding basic research. To have things take off, you've got to have commercial companies do it.

You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on... So it's a fixer-upper of a planet.

The odds of me coming into the rocket business, not knowing anything about rockets, not having ever built anything, I mean, I would have to be insane if I thought the odds were in my favor.

I'm interested in things that change the world or that affect the future and wondrous, new technology where you see it, and you're like, 'Wow, how did that even happen? How is that possible?'

We can't have, like, willy-nilly proliferation of fake news. That's crazy. You can't have more types of fake news than real news. That's allowing public deception to go unchecked. That's crazy.

The value of beauty and inspiration is very much underrated, no question. But I want to be clear: I'm not trying to be anyone's savior. I'm just trying to think about the future and not be sad.

I have made the mistaken assumption - and I will attempt to be better at this - of thinking that because somebody is on Twitter and is attacking me that it is open season. And that is my mistake.

On one of the SpaceX flights, we had a secret payload: a wheel of cheese. We flew to orbit and brought it back, so it was the world's first 'space cheese.' It was, in part, a tribute to Monty Python.

I think a lot of the American people feel more than a little disappointed that the high-water mark for human exploration was 1969. The dream of human space travel has almost died for a lot of people.

From an evolutionary standpoint, human consciousness has not been around very long. A little light just went on after four and a half billion years. How often does that happen? Maybe it is quite rare.

My vision is for a fully reusable rocket transport system between Earth and Mars that is able to re-fuel on Mars - this is very important - so you don't have to carry the return fuel when you go there.

Brand is just a perception, and perception will match reality over time. Sometimes it will be ahead, other times it will be behind. But brand is simply a collective impression some have about a product.

I think Tesla will most likely develop its own autopilot system for the car, as I think it should be camera-based, not Lidar-based. However, it is also possible that we do something jointly with Google.

My background educationally is physics and economics, and I grew up in sort of an engineering environment - my father is an electromechanical engineer. And so there were lots of engineery things around me.

If you look at our current technology level, something strange has to happen to civilisations, and I mean strange in a bad way. And it could be that there are a whole lot of dead, one-planet civilisations.

The future of humanity is going to bifurcate in two directions: Either it's going to become multiplanetary, or it's going to remain confined to one planet and eventually there's going to be an extinction event.

Trying to read our DNA is like trying to understand software code - with only 90% of the code riddled with errors. It's very difficult in that case to understand and predict what that software code is going 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.

Silicon Valley has evolved a critical mass of engineers and venture capitalists and all the support structure - the law firms, the real estate, all that - that are all actually geared toward being accepting of startups.

There's no better place in the world for technology start-ups than Silicon Valley; there's such an incredible well of talent and capital and resources. The whole system is set up to foster the creation of new companies.

With artificial intelligence, we are summoning the demon. You know all those stories where there's the guy with the pentagram and the holy water, and he's like, yeah, he's sure he can control the demon? Doesn't work out.

A battery by definition is a collection of cells. So the cell is a little can of chemicals. And the challenge is taking a very high-energy cell, and a large number of them, and combining them safely into a large battery.

Boeing just took $20 billion and 10 years to improve the efficiency of their planes by 10 percent. That's pretty lame. I have a design in mind for a vertical liftoff supersonic jet that would be a really big improvement.

Particularly Instagram, people look like they have a much better life than they really do. People basically seem like they are way better-looking than they really are, and they are way happier-seeming than they really are.

If you don't have sustainable energy, you have unsustainable energy. The fundamental value of a company like Tesla is the degree to which it accelerates the advent of sustainable energy faster than it would otherwise occur.

I like the word 'autopilot' more than I like the word 'self-driving.' 'Self-driving' sounds like it's going to do something you don't want it to do. 'Autopilot' is a good thing to have in planes, and we should have it in cars.

If you want to grow a giant redwood, you need to make sure the seeds are ok, nurture the sapling, and work out what might potentially stop it from growing all the way along. Anything that breaks it at any point stops that growth.

The space shuttle was often used as an example of why you shouldn't even attempt to make something reusable. But one failed experiment does not invalidate the greater goal. If that was the case, we'd never have had the light bulb.

If we could do high-speed rail in California just half a notch above what they've done on the Shanghai line in China, and if we had a straight path from L.A. to San Francisco, as well as the milk run, at least that would be progress.

To make an embarrassing admission, I like video games. That's what got me into software engineering when I was a kid. I wanted to make money so I could buy a better computer to play better video games - nothing like saving the world.

There are really two things that have to occur in order for a new technology to be affordable to the mass market. One is you need economies of scale. The other is you need to iterate on the design. You need to go through a few versions.

For all the supporters of Tesla over the years, and it's been several years now and there have been some very tough times, I'd just like to say thank you very much. I deeply appreciate the support, particularly through the darkest times.
