Brad Delong says that although they have improved productivity, in some ways, computers slow us down.
Computers are tremendous labor-saving devices. They give us power to accomplish extraordinary amounts of work in extraordinarily short intervals of time: financial analysis, data mining, design automation. But they also give us the capability to do things like play solitaire. Or send instant messages. Fiddle with fonts. Futz with PowerPoint. Twiddle with images. Reconfigure link rollovers.
At the organizational level, however, the uses of high tech that might be valuable for an individual can be pointless or counterproductive. Consider a meeting to decide between two courses of action. Often, the same decision would be made whether weeks were spent preparing overheads or no overheads were prepared at all. It's easy to see that, from the company's point of view, all the hours spent on PowerPoint slides are dissipated waste.
Very interesting take, but I think he is on to something.
