“The reason [James Clerk] Maxwell's Demon cannot exist is that it does take resources to perform an act of discrimination. We imagine computation is free, but it never is. The very act of choosing which particle is cold or hot itself becomes an energy drain and a source of waste heat. The principle is also known as "no free lunch."We do our best to implement Maxwell's Demon whenever we manipulate reality with our technologies, but we can never do so perfectly; we certainly can't get ahead of the game, which is known as entropy. All the air conditioners in a city emit heat that makes the city hotter overall. While you can implement what seems to be a Maxwell's Demon if you don't look too far or too closely, in the big picture you always lose more than you gain.Every bit in a computer is a wannabe Maxwell's Demon, separating the state of "one" from the state of "zero" for a while, at a cost. A computer on a network can also act like a wannabe demon if it tries to sort data from networked people into one or the other side of some imaginary door, while pretending there is no cost or risk involved.”

“Web 2.0 ideas have a chirpy, cheerful rhetoric to them, but I think they consistently express a profound pessimism about humans, human nature and the human future.”

“Style used to be an interaction between the human soul and tools that were limiting. In the digital era, it will have to come from the soul alone.”

“Advertisers are not thinking radically enough - they look for technology to lead instead of trying the neuroscience approach and thinking about what parts of the brain haven't been activated before. These new experiences bring new capabilities to the brain.”

“What does it mean to not be alone? I've approached that question through music, technology, writing and other means.”

“I think complexity is mostly sort of crummy stuff that is there because it's too expensive to change the interface.”

“Technologists provide tools that can improve people's lives. But I want to be clear that I don't think technology by itself improves people's lives, since often I'm criticized for being too pro-technology. Unless there's commensurate ethical and moral improvements to go along with it, it's for naught.”

“The wisdom of crowds works when the crowd is choosing the price of an ox, when there's a single numeric average. But if it's a design or something that matters, the decision is made by committee, and that's crap. You want people and groups who are able to think thoughts before they share.”

“The basic problem is that web 2.0 tools are not supportive of democracy by design. They are tools designed to gather spy-agency-like data in a seductive way, first and foremost, but as a side effect they tend to provide software support for mob-like phenomena.”

“If there's any object in human experience that's a precedent for what a computer should be like, it's a musical instrument: a device where you can explore a huge range of possibilities through an interface that connects your mind and your body, allowing you to be emotionally authentic and expressive.”

“I've always felt that the human-centered approach to computer science leads to more interesting, more exotic, more wild, and more heroic adventures than the machine-supremacy approach, where information is the highest goal.”
