Technological 'revolutions' don't really overthrow anything - they simply append a new and dynamic market to that which went before.

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.

The ever-growing size of software applications is what makes Moore's Law possible: 'If we hadn't brought your computer to its knees, why would you go out and buy a new one?'

A person's basic humanity is not governed by how he or she came into this world, or whether somebody else happens to have the same DNA.

The cloning procedure is similar to IVF. The only difference is that the DNA of sperm and egg would be replaced by DNA from an adult cell. What law or principle - secular, humanist, or religious - says that one combination of genetic material in a flask is OK, but another is not?

Politicians don't like to face unpleasant realities. In truth, nobody does, but as individuals, we have no choice; if we neglect to plan ahead, we are held accountable. Fail to meet your responsibilities at work, and you get fired. Ignore your car's gas gauge, and you get stranded.

An efficient government is dangerous in the hands of the wrong man. Sadly, the right sort of man never seems interested in the job.
