In the space of a week Gmail can call phones already and then reimagines the inbox. That's about two years' worth of product innovation. Plus, I'd forgotten this. You can have instant French subtitles as you chat in Gmail if you invite "firstname.lastname@example.org" to Chat, then start a group IM including the bot. Or Japanese (email@example.com). Since 2007 implausibly, clunky to add and getting some light.
