"Huh!  I don't think we've run into that problem - maybe because our population was barely approaching one billion, we were going to celebrate the milestone soon - but I expect that if it started happening, we'd have a big debate about whether dialects are glorious diversity or dangerous meta-protocol corruption.  I'd probably vote on the first side if the dialects still had a very easy time understanding each other, and there were no famous catastrophes being caused by 'yes' in one language meaning 'no' in the other.  If the concerned side won the vote by a supermajority, we'd probably try... finding people with very central dialects and making sure only they started pathways leading to careers in radio and television?  That's just me thinking very briefly, we'd actually run a big prediction market about what the results would be if we tried the top twenty-four strategies under consideration."
