The advance of technology is based on making it fit in so that you don't really even notice it, so it's part of everyday life.
Innovation will come from an ecosystem of pervasive computing so natural and all-encompassing that it disappears into the background.
Personal computing today is a rich ecosystem encompassing massive PC-based data centers, notebook and Tablet PCs, handheld devices, and smart cell phones. It has expanded from the desktop and the data center to wherever people need it - at their desks, in a meeting, on the road or even in the air.
If the Net becomes the center of the universe, which is what seems to be happening, then the dizzying array of machines that will be plugged into it will virtually guarantee that the specifics of which chip and which operating system you've got will be irrelevant.
I think there are two aspects to smart environments. One is information embedded in places and things. The other is location awareness, so that devices we carry around know where we are. When you combine those two, you get a lot of possibilities.
The Mac defined 'personal technology', and the iPhone defines 'intimate technology' as a convergence of communications, content and location.
I watch for emergent technologies and pay attention to what people say they'll be good for, then see what we actually use them for. It never occurred to me that a tiny telephone with a wireless transceiver would do whatever it is that it's done to us.
Web applications will become more and more ubiquitous throughout our human environment, with walls, automobile dashboards, refrigerator doors all serving as displays giving us a window onto the Web.
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. Before long, computers will be as trivial and plentiful as chairs and we will cease to be aware of the things. In fact I'm sure we will look back on this last decade and wonder how we could ever have mistaken what we were doing with them for "productivity"
We have this condition where digital technology is becoming increasingly smaller and distributed in the environment. In a certain sense, this is the first time ever we can describe a city in real time.
Every time you turn on your new car, you're turning on 20 microprocessors. Every time you use an ATM, you're using a computer. Every time I use a settop box or game machine, I'm using a computer. The only computer you don't know how to work is your Microsoft computer, right?
Computers are still technology because we are still wrestling with it: it's still being invented; we're still trying to work out how it works. There's a world of game interaction to come that you or I wouldn't recognise. It's time for the machines to disappear. The computer's got to disappear into all of the things we use.
Whatever people thought the first time they held a portable phone the size of a shoe in their hands, it was nothing like where we are now, accustomed to having all knowledge at our fingertips.
Our ever-present mobile devices provide the immediate and convenient information necessary to make sharing things truly irresistible.
Mobile communications and pervasive computing technologies, together with social contracts that were never possible before, are already beginning to change the way people meet, mate, work, war, buy, sell, govern and create.
As more and more of our world becomes part of the wireless network, I see the mobile phone becoming a central command station for everything around us.
The marriage of computing and connectivity without the shackles of being tethered to a location is one of the biggest disruptive forces of modern times.
Computing has gone from something tiny and specialized to something that affects every walk of life. It doesn't make sense anymore to think of it as just one discipline. I expect to see separate departments of user interface, for example, to start emerging at universities.
The only thing I do on a computer is play Texas Hold 'Em, really. Obviously my cell phone is a computer. My car is a computer. I'm on computers every day without actively seeking them out.
Imagine you are walking in China, and all the billboards are in English. And at the restaurants, as the people are talking to you, there are live subtitles. You don't even realize you are in a computer; it's just happening.
I envision a world where our smartphone is central to our lives in a non-obtrusive and intelligent way.
We have never lived in a time with the opportunity to put a computer in the pocket of 5 billion people.
The power of change that mobile technology unleashes is extraordinary.
The moonshot for Google Glass is to harmonize the physical and digital worlds. It is specifically to find a way to help people be naturally, elegantly situated, physical and digitally, at the same time.
In 20 or 30 years, you'll be able to hold in your hand as much computing knowledge as exists now in the whole city, or even the whole world.
