“The year is 2020. I zap some FooCoin at beveragecopter to refill my cup. Bartender flips the TV to talking heads debating which cryptos are really truly ‶money″. Viewers are charged per second via HTML5 eye-tracking APIs. I sigh, exasperated, look away, stick in my ear plugs.”
“This IBM electronic tube assembly cuts through the unknown like a rocket through the stratosphere.

It calculates payrolls, inventories, costs; points out savings of time and money.”
