In politics, religion and other areas of culture, people disagree on the worth of competing ideas. There is no equivalent to the scientific method that can determine in a robust way which ideas match the real world, and which ones can be ruled out. So conflicting ideologies persist indefinitely.
Suppose that every prospective parent in the world stopped having children naturally, and instead produced clones of themselves. What would the world be like in another 20 or 30 years? The answer is: much like today. Cloning would only copy the genetic aspects of people who are already here.
In market research I did at Microsoft Corp. in the early 1990s, I estimated that the 'Wall Street Journal' took in about 75 cents per copy from subscribers, $1.25 at the newsstand and a whopping $5 per copy from ads. The ad revenue let them run a far bigger newsroom than subscribers were paying for.
People get cranky when you burst their bubble. Over time, advances in astronomy have relentlessly reinforced the utter insignificance of Earth on a celestial scale. Fortunately, political and religious leaders stopped barbecuing astronomers for saying so, turning their spits with human-rights activists instead.
When I was about nine years old, I announced to my mother that I was going to cook Thanksgiving dinner. And I went to the library and got this whole pile of books. I'd love to say it all turned out great. It didn't. But, sort of, from that point on, whenever there was serious cooking at home, I was the one who did it.
Anybody who can afford a box of business cards can afford a Web site. Any company with an 800 number can move its services to the Web for peanuts by comparison. The extreme case of corporate promotion is to strip away all other aspects of your business and sell goods or services via the Net alone, as amazon.com has done with books.
I've been on a team that won the world championship of barbecue. But barbecue's interesting, because it's one of these cult foods like chili, or bouillabaisse. Various parts of the world will have a cult food that people get enormously attached to - there's tremendous traditions; there's secrecy.
Pressure cookers are relatively inexpensive, they're in every kitchen store, your grandma probably had one, but a lot of people don't. A pressure cooker is interesting because by pressurizing the vessel, you're able to cook much hotter than the boiling point of water, and still have water be present.
The way Moore's Law occurs in computing is really unprecedented in other walks of life. If the Boeing 747 obeyed Moore's Law, it would travel a million miles an hour, it would be shrunken down in size, and a trip to New York would cost about five dollars. Those enormous changes just aren't part of our everyday experience.
Elections, for their part, are typically popularity contests rather than measures of candidates' relative competency or effectiveness. Imagine if scientific truth were determined according to which scientist was most popular. To be successful, scientists would have to be charismatic and attractive - and human knowledge would suffer terribly.
There is a one-in-300 chance that Earth will be struck on March 16, 2880, by an asteroid large enough to destroy civilization and possibly cause the extinction of the human race. But, on the bright side, Prince could re-release his hit song with the new refrain 'We're gonna party like its twenty-eight seventy-nine.'
We're more familiar with what economists call an English auction - prices start low and rise as people bid. However, there is also the Dutch auction, where prices start high and go lower until somebody bites. Movies are sold to the audience via a very slow Dutch auction, where each phase between price drops can last weeks or months.
Regardless of how it's done, transaction costs will continue to plummet as computers get more powerful. Low transaction costs are a wonderful thing if you're in the transaction business. They're wonderful for consumers too, making it cheaper and easier to buy things and creating new things to buy.
