I don't think the discussion is practical. If we are all going to learn a new language, why not Chinese? French is actually very easy for people who speak Indo-European languages, but no easier for Chinese or Japanese speakers. In any case, I think one of the reasons why e.g. Finnish and Swedish participation is so good in the IETF is that in both countries English is learned from an early age. Whether that's fair or not, it's very practical. We can't all learn each others' languages, because there are too many of them. So it makes sense to pick a language, and the unfairness that comes from picking a language seems unavoidable. I don't see how picking a second language would help. It would still be unfair to just as many people—the only difference would be that a few more people would in some sense be privileged. So I think that whatever accommodation successfully occurs, it will be an accommodation involving people being more patient and understanding, not IETF participants as a group learning more languages.
