If one girl with courage is a revolution, imagine what feats we can achieve together.

The supreme challenge of Labor is to recognise our 'revolutionary moment' when it arrives. And to have the courage to seize it - wholly, boldly, and completely.

Courage to be is the key to revelatory power of the feminist revolution.

To be yourself is truly a revolutionary act, and I think more and more people should try it, because it's gotten me a pretty cool life.

While the digital transformation of industries will be profound, we must keep in mind that it will have wider economic and social impact, too, as with previous revolutions driven by steam and coal, electricity and computers.

This is a man who was 23 years old when he theorized the idea of creating a programmable machine, and in that way, Turing foresaw computers and artificial intelligence. These were revolutionary ideas at that time.

The technological revolution at home makes it much easier for computers to do our work.

At our computer club, we talked about it being a revolution. Computers were going to belong to everyone, and give us power, and free us from the people who owned computers and all that stuff.

And it's here and it's ready and we can really revolutionize the way we educate our children with tablet computers, and I'm committed to doing whatever I can to speaking to whomever I can to send this signal - to pound this message home. Now is the time.

I've always been at the intersection of computers and whatever they can revolutionize.

If we can make computers more intelligent - and I want to be careful of AI hype - and understand the world and the environment better, it can make life so much better for many of us. Just as the Industrial Revolution freed up a lot of humanity from physical drudgery I think AI has the potential to free up humanity from a lot of the mental drudgery.

Coding is like writing, and we live in a time of the new industrial revolution. What's happened is that maybe everybody knows how to use computers, like they know how to read, but they don't know how to write.

The digital revolution is far more significant than the invention of writing or even of printing.

I am still cautiously hopeful about the potential of the Internet. But it seems that the greatest revolution in communication has been hijacked by commercial values.

It's extraordinary that revolutions taking place around the world were sparked by communication on the Internet.

As a graduate student at Oxford in 1963, I began writing about books in revolutionary France, helping to found the discipline of book history. I was in my academic corner writing about Enlightenment ideals when the Internet exploded the world of academic communication in the 1990s.

However revolutionary it may be, the Internet still hasn't altered the basic law of human communication: Being nice to your interlocutors is a good way to start any negotiations, particularly, when being hostile is an open invitation for a cyber-fight.

I do a little fact checking now and then. Other than that its impact is simply that email has revolutionized communication for me, and my website has built up a community of readers, which is a lot of fun.

Anything can change, because the smartphone revolution is still in the early stages.

The clear and present danger of climate change means we cannot burn our way to prosperity. We already rely too heavily on fossil fuels. We need to find a new, sustainable path to the future we want. We need a clean industrial revolution.

You have to understand that to have a revolution when you are 18 years old is completely different from normal political leaders who were born in a democracy and will die in a democracy and never to have experienced that change. I have seen that change.

Especially in technology, we need revolutionary change, not incremental change.

I want a real revolution, a real change in society: society, a great organic mass of well-regulated forces used for the bringing-about a happy life for all.

A lot of people think the Breakfast for Children program is charity. But what does it do? It takes the people from a stage to another stage. Any program that's revolutionary is an advancing program. Revolution is change.
