Albert was checking his work emails on his phone late on Wednesday night. His grandfather had foreseen all this. One day, his grandfather had solemnly predicted to Albert, there will be computers so small that we’ll be able to carry them in our pockets. Then, he added, we’ll be able to get all our work done in a couple of hours. Our only problem, his grandfather went on, will be thinking up ways to spend all our free time. Albert read ninety three tedious emails, all of them telling him the same thing: that his grandfather had been very, very wrong.
