I know the counterarguments, starting with the changing economic environment in which I have found myself making this decision. There are many of my fellow baby boomers who would love to retire but no longer can afford to do so. There are many who feel they have been pushed from their jobs by younger workers who are cheaper, and perhaps less able. When Chesley Sullenberger landed a passenger jet safely on the Hudson River, I joined the rest of the nation in thanking God that a man who had been flying for a lifetime and a crew of veteran flight attendants were working that day.

But those thoughts are also balanced by my feeling that many of us of a certain age have had a great deal of difficulty with the concept of getting older. There would have been no need for a product called Not Your Daughter's Jeans when I was a teenager because my mother would never have thought of dressing like me, or doing things to her face to convince others that we were sisters. Today we have an entire generation of Americans who seem dedicated to the proposition that they will fight aging to the death. Quite literally. And that means staying front and center professionally. The unspoken synonym for "emeritus" is "old." And old is a word we don't even use anymore in polite conversation, a modern obscenity.

It's particularly glaring when this generational stall happens in the news business, which constantly remakes itself in the image and likeness of the world. And it is egregious when it happens in the small subset of the pundit class, which is supposed to take the nation's temperature. It's undeniable: America's opinionators are too white and too gray. They do not reflect our diversity of ethnicity and race, gender and generation. They do not reflect the diversity of opinion, either, mainly because most are part of an echo chamber of received wisdom that takes place at restaurant tables in New York and Washington. Conservative pundits are making themselves foolish, flailing wildly because their movement itself is aging, confounded by the popularity of a president who stands for much of what they revile. But liberals are little better, fighting the same old battles in the same old ways, as though the world during their tenure had not changed radically.

One of those changes is in technology, and because of it young people in the news business have been able to exact a kind of inadvertent revenge. They seized on an information-delivery system that their elders initially found puzzling or unpersuasive. They created online outlets from the ground up. Now that this is where the action is, they are quite properly part of the action, not because we made room for them, but because they invented room for themselves.

I'm not sure what the future is for the print parents of these cyber-outlets, which puts me about even with the people who are running them. Even Brenda Starr, the red-haired comic-book character who convinced me as a child that being a reporter was glamorous, has been laid off. But I do know that journalism will have to keep changing as this country changes. It will have to reflect the interests of people in their 20s and 30s, not merely complain that people in their 20s and 30s don't behave the way their elders do. There is nothing quite as tedious, or as useless, as ritual recitations of the good old days, which most often weren't.

Throughout the country there seems to be an understanding that this is and ought to be a time of reinvention, in the economy, in education, in the office. But no one seems eager to reinvent on an individual level. Yet never has there been a time when fresh perspective and new ideas were more necessary. The linear path, the ladder, emphasizes stability, but too often at the expense of innovation and mobility. It's always seemed to me that running a company well ought to be like a variant of musical chairs; every few years everyone should move around to someplace else, some position where they will learn new things. I have changed jobs many times in almost 40 years (40 years!) of word work, including work as a novelist that I will continue. Experience often brings wisdom, but also sometimes torpor and fatigue.

As a columnist you not only think about these matters, you also discover that they have real-life applications, and the real life may be your own. Watching a black man born in the 1960s, who likes to say his father was from Kenya and his mother from Kansas, barnstorm across America, I began to have inconvenient thoughts about myself. Barack Obama hopscotched over an entire generation of politicians to reach the White House; he had not waited his turn because a majority of the American people decided that he ought not to do so. They agreed that the country needed change.

And I believe it does, too. I believe that many of our old ways of doing things are out of date, including some of our old ways of looking at, and reporting on, the world around us. Since the day he delivered his Inaugural Address, when I was 8 years old, people have been quoting the youthful John F. Kennedy saying that the torch had been passed to a new generation. But torches don't really get passed very much because people love to hold on to them.

This page, this place, is an invaluable opportunity to shed some light. But if I had any lingering doubts about giving it up after almost nine years, they were quelled by those binders on my desk, full of exemplary work by reporters young enough to be my children. Flipping through their pages, reading such essential and beautifully rendered accounts of life in America and around the world, I felt certain of the future of the news business in some form or another. But between the lines I read another message, delivered without rancor or contempt, the same one I once heard from my own son: It's our turn. Step aside. And now I will.
