Ever since I was young I knew telephones were evil. They would interrupt people rudely at any time of the day or night. Today was different. The phone rang and I picked it up. During the conversation I was informed that the little woman had shopped in Winnipeg and not informed me she had bought up a good stock of preserving jars for beets! They were in the trunk of the car out in the garage. Aha! I am now back at work boiling and pickling beets. At the rate I am going the beets in the ground are unlikely to be harvested fully. I am a wheelbarrow behind on the pickling. About now, the little woman might do the maths and realize we have enough for a year, or two… Then there are the carrots still remaining to be harvested and the ground cultivated to incorporate all the weeds and crop residues.
So, sometimes telephones do good service. I still am convinced that CPUs should be interrupted, not people. People should be able to work asynchronously. That’s why God made e-mail, after all.
