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.

One of the things that I love to do is travel around the world and look at archaeological sites. Because archaeology gives us an opportunity to study past civilizations, and see where they succeeded and where they failed. Use science to, you know, work backwards and say, 'Well, really, what were they thinking?'

The techniques of being an Internet visionary are just like those of lower-tech fortunetellers through the ages. A technological visionary must tell people what they want to hear, because your company's stock won't rise if you spout an unpopular vision to analysts.

Most visions of extraterrestrial life are actually steeped in human hubris. The fictional extraterrestrials of 'Star Trek' or a hundred other space operas are less alien than many of my neighbors. And funny, the ones running the place are mostly WASPish men.

The depressing thing about battery technology is that it gets better, but it gets better slowly. There are a whole bunch of problems in materials science and chemistry that come in trying to make existing batteries better.

In the early days of the software industry, people cared about copyright and didn't give a damn about patents - they copied each other willy-nilly.

Suppose that 'Unsolved Mysteries' called you with news of a long-lost identical twin. Would that suddenly make you less of a person, less of an individual? It is hard to see how. So, why would a clone be different? Your clone would be raised in a different era by different people - like the lost identical twin, only younger than you.
