Automation Improves Safety

The airports with their self-check-in kiosks and restaurants full of iPads are staffed by thousands of human workers (most using mano machine can do? Or, like operating an elevator and driving a car, is it because at first we don't trust machines to do a job where lives are at risk? Elevators became much safer as soon as the human operators were replaced. The human-hating Skynet from the Terminator movies could hardly do a better job of killing people than we do killing ourselves with cars. H...

 Understanding the Education Customer

VCs and entrepreneurs tend to be well educated. Well educated people think about education as an investment. You put as many of your resources in to an investment as you can. It may take 20 years to pay off, but if the return-on-investment is high (which it is for education) then you invest. This group of people — if you’re reading this, you fall into this group — generally understand that education is an investment, and as a result are price insensitive and will optimize for quality ...

 Cultural Homogenization Makes Travel Pointless

But she thought of Kuno as a baby, his birth, his removal to the public nurseries, her own visit to him there, his visits to her-visits which stopped when the Machine had assigned him a room on the other side of the earth. "Parents, duties of," said the book of the Machine," cease at the moment of birth. P.422327483." True, but there was something special about Kuno - indeed there had been something special about all her children - and, after all, she must brave the journey if he desired it. ...

 RPG as Sophisticated Make-Believe

A roleplaying game is, in may ways, a sophisticated version of the childhood game of make-believe. If you ever played cops-and-robbers (or cowboys and indians, or army), you remember the arguments about who shot whom, or how quickly you could reach cover before you got blasted by some bad guy, or how much damage a hand grenade did to a bunker, and so on. One of the main differences between roleplaying games and childhood games is that hte rules answer all these questions, and more: The rules...

 The Monty Hall Problem

Here’s how Monty’s deal works, in the math problem, anyway. (On the real show it was a bit messier.) He shows you three closed doors, with a car behind one and a goat behind each of the others. If you open the one with the car, you win it. You start by picking a door, but before it’s opened Monty will always open another door to reveal a goat. Then he’ll let you open either remaining door. Suppose you start by picking Door 1, and Monty opens Door 3 to reveal a goat. Now what should y...

 DNA is not a Blueprint

Textbooks of biology repeat time and again that DNA is a 'blueprint' for building a body. It isn't. A true blueprint of, say, a car or a house embodies a one-toone mapping from paper to finished product. It follows from this that a blueprint is reversible. It is as easy to go from house to blueprint as the other way around, precisely because it is a one-to-one mapping. Actually, it's easier, because you have to build the house, but you only have to take some measurements and then draw the blu...
