I am about to do something rash, which is to disagree with Lucy Kellaway. Last week, the fearless observer of business follies went too far: she called for PowerPoint to be banned.

The prosecution’s argument is simple: many PowerPoint presentations are very bad. This is true but it hardly makes the case for a ban. Serviceable tools can produce awful results in the wrong hands, as anyone who has seen me put up shelves can attest. Banning the screwdriver is not the answer.

So it is with PowerPoint. It’s an unromantic, practical piece of kit. It is often used poorly. It is not the most elegant tool, but botched jobs must be blamed on the workman. Many of the bad presentations people deliver with the help of PowerPoint would have been bad presentations in any case. Would it have been better to hear the impromptu ramblings of a nervous speaker in total cognitive meltdown? Or to watch a piece of professionally produced but irrelevant film, in the dark? Many readers will remember corporate life before PowerPoint. It was no lost Eden.
