What few acknowledge is that the online world — when compared with offline, analog diversity — is very nearly a monoculture, an echo chamber where the planet’s few dominant cultures talk among themselves. English, Chinese, Spanish, Arabic and just a handful of other languages dominate digital communication. Thanks to their sheer size and to the powerful official and commercial forces behind them, the populations that speak and write these languages can plug in, develop the necessary tools and assume that their languages will follow them into an ever-expanding range of virtual realms.
