I am much less concerned with whatever it is technology may be doing to people that what people are choosing to do to one another through technology. Facebook's reduction of people to predictively modeled profiles and investment banking's convolution of the marketplace into an algorithmic battleground were not the choices of machines.

One argument against open systems is that they become open to everything, good and bad. Like a Richard Meier skyscraper, the anal retentive, Bauhaus elegance of the Mac does prevent the loose ends and confusion of a less sterile environment. But it also prevents fertility. Apple's development must come from within.

The new Zune may not be an iPod killer, but it does offer a clean interface, great industrial design, HD radio, and a subscription model for music, making it significantly less expensive for big users.

With the DVR, I was mostly writing about it as a good thing in giving us the choice of when and how to watch things. But there's what we lose in the bargain, which is the collective spectacle. 'Did you see Jay Leno last night?'

The first step toward maintaining autonomy in any programmed environment is to be aware that there's programming going on. It's as simple as understanding the commercials are there to help sell things. And that TV shows are there to sell commercials, and so on.

The iPad - contrary to the way most people thought about it - is not a tablet computer running the Apple operating system. It's more like a very big iPhone, running the iPhone operating system.

The cloud is still really just a bunch of servers, owned by someone or something, whose decisions and competence must be trusted. This applies to everything from Google Docs to Gmail: Putting our data out there really means putting it 'out there.'
