To the guy who reckoned that the number of Gaelic speakers was far fewer than the 50-odd thousand responding to the 2001 census, you obviously haven't been to the Western Isles lately. As the article refers to 'going up the A9' and expecting to see Scotland from that as a vantage point, it's hardly surprising...
It's perfectly normal to nip into the co-op either in Daliburgh in South Uist or just over the causeway in Benbecula and hear mother and infant nattering away in Gaelic. There, bilingualism meant the recent addition of **English** to the Gaelic-only roadsigns I remember from the holidays in the 70s and 80s back when I was a wee nipper.
What place does Gaelic have in the world today? You might better ask what place does English have in a world where American displaced it at least a decade ago. Having lived for the last 20 years 'down south' where Mockney, dumbing-down and grocers apostrophe's long ago replaced any real, joined-up language, I can confirm that what used to be referred to as the Queen's English is currently making its last stand somewhere in the Netherlands.
I'm in two minds about the thumbs up given by a previous commentator to Neil Oliver's 'History of Scotland'; it's too simple a story, trying to bash together into a single narrative what was in reality at least three separate stories, that just happened to take place at the same point in history and accidentally result in the Scotland that all we exiles love. And big ones too (usual joke).
It's not a justification for the per-head extra cost of the BBC Alba service, but then that's trying to give an answer to the wrong question; the Gaels have faced down rampant attempts to exterminate their language in the past, and the simple indifference being expressed in these comments they will be able to brush aside as if they weren't there.
Fact is, the language comes out of the different outlook and lifestyle of the people and as long as these survive Gaelic will survive. BBC Alba, Freesat etc etc are nice to have add-ons, but not essential for the survival of either language or people.
