#analysis – What’s wrong with BBC’s ‘Bowel Cancer Map’?

“This is a common characteristic of technology that its champions do not like to talk about, but it is why we have so many bubbles in this industry.

The change is so important, often world-changing, that it is hard to value, so people overshoot toward the infinite. When it turns out to be merely huge, there is a crash – in railroad bonds, or RCA stock, or Pets.com. Perhaps Big Data is next, on its way to changing the world.”
