Will everything be digital.
What happens in a world in which atoms are replaced by bits? In which everything that was wired becomes wireless, and vice versa?
The important thing to remember is that bits are bits. In the digital world there are no movies or magazines or pieces of music. There are just 1s and 0s, for which we did not even have a name until 1946 when Princeton statistician John Tukey concatenated the words binary and digit into the term bit.
For the next 25 years, bits were of interest only to a few specialized members of the scientific community. But of late, bits have become important to everybody, because we can represent anything as bits—anything. In the not-too-distant future, we'll be able to describe the human body with bits and try out new drugs on these models rather than on living beings.
Books and magazines and newspapers are not the meaningful element. Words are one of the most powerful and efficient forms of human communication. A few words - i.e., a few bits—can create religions, can make war or peace. Those words when presented to the eye are presented as text. In the past we could render text only by printing it on paper, carving it in stone, writing it with smoke.
Today we can do something new. We can reduce the text to bits, which we cannot see or hear, take this new representation and store it, manipulate it or transmit it, and then later render it on a computer display or a piece of paper. The same is true of music, movies, still photographs. While this is widely recognized, few people have a sense of the quantity of bits needed to achieve one representation vs. another. For example, when you read a book, you consume about 3 million bits an hour. When you look at television, you consume 3 million a second. UNDERSTANDING BANDWIDTH. Bandwidth is the ability to move bits. Broadband is the ability to move a lot of bits per second. Though everybody seems to do it, likening bandwidth to the diameter of a pipe is misleading, because our consumption of bits is not analogous to drinking from a garden or fire hose. We don't necessarily consume bits in a continuous fashion (like water), and even if we did, that does not perforce mean our computers have to receive them that way.
One of the most profound changes afforded by the digital world is the ability to be asynchronous, in the smallest and largest time scales. In the smallest sense, this allows us to use efficiently our channels of communications; for example, interleaving people's conversations—packetizing them—so that many people share the same channel without being aware that they are. In the larger sense, we can expand, contract and shift our personal time in new ways, leaving and receiving messages at mutual convenience. On a yet larger scale, social behavior will also become more asynchronous, with all of us moving in much less lockstep rhythm and with more personal cadence than we do today.
But in this new world, more bandwidth is not necessarily good, or even what we want. And, when we do want it, it is not necessarily in order to sit in front of a device and consume a few billion bits an hour. Moreover, the dominant user of the Net in the future will not be people at all. It will be machines talking to one another in ways we cannot imagine. For them, trickle charging information or blasting at a billion bits a second are options not directly meaningful to people. Increasingly, these bits will arrive wirelessly.
BEING WIRELESS. Plugs are the past. The need to be tethered is disappearing for two reasons: better battery technologies (and less power-hungry devices) and improved use of radio frequencies, so-called RFs. Eventually, everything electric will talk with everything else electric, using very fine-grained, wireless communications. Ultimately, all long-distance traffic will be fiber and all short-distance traffic will be RF.
Today you may have one or two dozen wireless devices (radio, cell phone, TV, pager, car key). Tomorrow, you will probably have thousands of them.
One place you’ll find these micro wireless devices will be on packaging, when RF identification tags replace the Universal Product Code—those little vertical bars read by supermarket checkout scanners. With emerging print technologies, it will be possible to print active tags directly onto containers—tiny computers that broadcast their ID, price and other characteristics (such as the expiration date). A refrigerator or a medicine cabinet can thus know what is inside it. A container could be aware of the absence or presence of each pill. In the future, all these inanimate objects will be able to talk to one another and pass messages among themselves.
