Languages
I reckon English will well and truly become the universal language – meaning really universal, like in Starship Troopers where even in Buenos Aires they speak straight English. Especially when 95% of e-mail communication (more so on ICQ nowadays – its quicker and more convenient than e-mail, which is what we were saying about e-mail vs snail mail only a year or two ago) is in English. Too bad the number of people in the world who have computers is less that 1% or something… and most third-world countries don’t speak English, but of course, this’ll change in the distant future.
