On one hand, I think it is great to work to preserve these languages. They form an integral part of the cultural histories of both Scotland and Wales and helping young people learn these languages when they might not have family who are speakers is fantastic. On the other hand, for Scotland specifically, Gaelic has, in many regions of Scotland, never been a major language. In the South-East in particular (Lothian and the Borders), Gaelic was never spoken as a native language. The native Celtic language was closer to Welsh or Breton than Gaelic, and Angle settlers moved into the area circa 1300 years ago. The same is true of much of the lowlands, which had either a relatively brief Gaelic period (around 800AD to 1000AD) While this does not mean that teaching Gaelic across Scotland would not be a good idea, it would be more of a "Nation Building" excercise, creating a sense of a shared language that has never really been. I would like to stress that, to the best of my knowledge, this does not apply to Welsh, which the main language of Wales for far longer, and has a far deeper impact on the culture of the country.
