Speaking as a lowlander with no (recent) connection to Scottish Gaelic or the Hebrides; I've started learning it and I'm enjoying it immensely. It isn't as complex as some make out. And in terms of resources and coverage, its never been better for Scottish Gaelic. Yet we could still be doing better.

Though I have to admit, despite loving Gaelic, I sometimes worry that I could be better off learning a more widespread language like French, Spanish or German.(ofcourse there's no reason why you can't do both, but it does take more time) With the fraught job market, I worry I could make a better living with one of those languages instead, moving to a different country etc. This is obviously more a problem with learners rather than native speakers of gaelic - but i think it is a relevant one. Though there are lots of jobs for gaelic speakers as well, which is a positive.
