Counterpoint
I'm not quite D.J. Tice's age, but we're generational peers who apparently see the world differently. Where Tice sees a "plateau" in terms of progress ("Has progress plateaued?" Nov. 18), I'm walking around with a silly grin thinking about how much has changed in my lifetime, and about what's yet to come.
Let's start with computers. When Tice and I were in high school, in the 1960s and '70s, computers were in business, science and the public's imagination, but not directly in people's lives. Computers were massive things locked away in isolation chambers, attended to by technicians in white coats and dedicated to the massive problems of business, government and science. They were expensive, fragile, balky and incredibly underpowered by today's standards.
In 1969, for example, Apollo 11 went to the moon and back with a state-of-the-art computer packing 2,048 bytes of memory. Sounds impressive until you realize that it's about 1/4,000,000 as powerful as the computer sitting on my desk.
Last year, well more than a billion computing devices were sold worldwide -- computers, tablets, smart phones. That doesn't count the computing power that's built into our cars, coffeemakers, toasters and washing machines. It doesn't include the computers that let the deaf hear through cochlear implants, that help control modern prosthetic limbs or that let the remarkable mind of Stephen Hawking continue to communicate with the world. It doesn't count the processors embedded in every aircraft sold, in every farm machine, in every crane, bulldozer or grader.
The introduction of this much computing power has revolutionized human experience. In business, medicine, science, commerce and the military, computing power has raised the efficiency of planning, manufacturing and operations. It has found patterns hitherto undetectable in tracking the spread of disease, in locating connections between terrorists, the flow of currencies and commodities across global markets, and the shopping patterns of soccer moms and empty nesters. It is used to predict global weather, the likely course of a tsunami and how many cases of bottled water should be shipped to warehouse stores in disaster areas. In truth, it's hard to think of what hasn't been affected by the computers.
A parallel rise has occurred in telecommunications. In 1970, about the only "data pipe" running into a home, a business, a research center or an academic institution was a "plain old telephone system" consisting of a single copper wire. The only other ways information came into these establishments were through low-bandwidth, analog channels like radio, television, newspapers, the Post Office and the neighbor across the back fence.
Today, we are awash in high-speed connectivity. The average American spends her day within range of multiple cellular networks, wireless data networks, satellite feeds, cable connections, fiber optics and more. These connections can stream inconceivable amounts of data. In the time it takes to read this sentence, any one of them can transmit more than 3,500 DVDs worth of data.
