The most advanced military jets are fly‑by‑wire: They are so unstable that they require an automated system that can sense and act more quickly than a human operator to maintain control. Our dependence on smart technology has led to a paradox. As technology improves, it becomes more reliable and more efficient, and human operators depend on it even more. Eventually they lose focus, become distracted, and check out, leaving the system to run on its own. In the most extreme case, piloting a massive airliner could become a passive occupation, like watching TV. This is fine until something unexpected happens. The unexpected reveals the value of humans; what we bring to the table is the flexibility to handle new situations. Machines aren't collaborating in pursuit of a joint goal; they are merely serving as tools. So when the human operator gives up oversight, the system is more likely to have a serious accident.

Followers can be defined by their position as subordinates or by their behavior of going along with leaders' wishes. But followers also have power to lead. Followers empower leaders as well as vice versa. This has led some leadership analysts like Ronald Heifetz to avoid using the word followers and refer to the others in a power relationship as "citizens" or "constituents." Heifetz is correct that too simple a view of followers can produce misunderstanding. In modern life, most people wind up being both leaders and followers, and the categories can become quite fluid. Our behavior as followers changes as our objectives change. If I trust your judgment in music more than my own, I may follow your lead on which concert we attend (even though you may be formally my subordinate in position). But if I am an expert on fishing, you may follow my lead on where we fish, regardless of our formal positions or the fact that I followed your lead on concerts yesterday.

Color is an interpretation of wavelengths, one that only exists internally. And it gets stranger, because the wavelengths we're talking about involve only what we call "visible light", a spectrum of wavelengths that runs from red to violet. But visible light constitutes only a tiny fraction of the electromagnetic spectrum ― less than one ten-trillionth of it. All the rest of the spectrum ― including radio waves, microwaves, X-rays, gamma rays, cell phone conversations, wi-fi, and so on ― all of this is flowing through us right now, and we're completely unaware of it. This is because we don't have any specialized biological receptors to pick up on these signals from other parts of the spectrum. The slice of reality that we can see is limited by our biology.

What is unusual about journalism as a profession is its lack of independence. In theory, practitioners in the classic professions, like medicine or the clergy, contain the means of production in their heads and hands, and therefore do not have to work for a company or an employer. They can draw their income directly from their clients or patients. Because the professionals hold knowledge, moreover, their clients are dependent on them. Journalists hold knowledge, but it is not theoretical in nature; one might argue that the public depends on journalists in the same way that patients depend on doctors, but in practice a journalist can serve the public usually only by working for a news organization, which can fire her or him at will. Journalists' income depends not on the public, but on the employing news organization, which often derives the large majority of its revenue from advertisers.

In most of the world, capitalism and free markets are accepted today as constituting the best system for allocating economic resources and encouraging economic output. Nations have tried other systems, such as socialism and communism, but in many cases they have either switched wholesale to or adopted aspects of free markets. Despite the widespread acceptance of the free-market system, markets are rarely left entirely free. Government involvement takes many forms, ranging from the enactment and enforcement of laws and regulations to direct participation in the economy through entities like the U.S.'s mortgage agencies. Perhaps the most important form of government involvement, however, comes in the attempts of central banks and national treasuries to control and affect the ups and downs of economic cycles.
