The one-language world has been a recurring dream over the centuries, but it's only in the past century that we've been really verging on a truly universal lingua franca. But even now most people in the world still don't speak standard American or UK English with native fluency, so I think regional languages will be stickier than some people give them credit for. Minority languages will continue to die out, but that's not necessarily the fault of English (except in some cases, e.g. Irish or Native American languages). Rather, existing regional languages crowd out minority ones.
