According to census reports there are around 50,000 native speakers of Scottish Gaelic. The DuoLingo language app had had spectacular success with its Scottish Gaelic course, with about a million people signing up to learn it.
This means that a very short time there could be about twenty times as many non-native speakers of Scottish Gaelic than native speakers. If any mistakes or errors have crept into the DuoLingo course, the entire language could be affected.
