It's a beautiful aspiration, and Logo contains many striking ideas. But as far as we know, no professional differential geometer (or, more generally, mathematician) uses Logo seriously as a tool in their work. And upon reflection that seems troubling. If Logo genuinely expresses the ideas of differential geometry, why don't differential geometers use it? You start to wonder: might it be that Logo leaves out important ideas about differential geometry, maybe even the most important ideas about differential geometry? After all, while mathematically trained, Papert wasn't himself an accomplished differential geometer. How would he even have known what to include? And certainly most of the people interested in Logo aren't qualified to make that judgment.
