When you learn to read and write, it opens up opportunities for you to learn so many other things. When you learn to read, you can then read to learn. And it's the same thing with coding. If you learn to code, you can code to learn. Now some of the things you can learn are sort of obvious. You learn more about how computers work.

I started my career as a journalist, writing about science and technology for 'Business Week' magazine. Then I decided to make a career shift. I went to graduate school in computer science, and I began developing educational technologies - in particular, technologies to engage children in creative learning experiences.

With 'Scratch,' you create computer programs by snapping together graphical programming blocks, much like LEGO bricks, without any of the obscure syntax and punctuation of traditional programming languages. After creating an interactive 'Scratch' project, you can share it on the 'Scratch' website, just as you would share videos on YouTube.

If I'm serious, yes, I'd like to have done what Shakespeare did... to act and write. You learn so much from acting. One of our great writers, Alan Bennett, does both supremely well. When I write a story, I tend to speak it aloud as I'm writing it.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
