When digital culture first came along, it was supposed to create more time, by allowing us to shift time around. Somehow instead we've strapped devices to ourselves that ping us all the time.

In the industrial age and in analog clocks, a minute is some portion of an hour which is some portion of a day. You know, in the digital age, a minute is just a number. It's just 3:23. It's almost this absolute duration that doesn't have a connection to where the sun is or where our day is.

We're living in an economy where productivity is no longer the goal, employment is. That's because, on a very fundamental level, we have pretty much everything we need. America is productive enough that it could probably shelter, feed, educate, and even provide health care for its entire population with just a fraction of us actually working ... Our problem is not that we don't have enough stuff-it's that we don't have enough ways for people to work and prove that they deserve this stuff.

There's all sorts of poisons and mined minerals and carnage that goes on to make a tablet. Way more than to print a book. Or a bunch of books.
