I have three kids and I seriously doubt their kids won't speak the language of their parents (assuming they'll live in Iceland).
The transition happens much slower, although I've been watching it accelerate over the past couple of decades. English is encroaching on the language. We speak Icelandic, but there are small grammatical changes happening, making the language more English - and at the same time, we're losing Icelandic vocabulary.
My prediction is that my grandkids (that's probably at least 13-15 years in the future (hopefully)) will speak Icelandic very similar to what I do, it'll just be a liiiittle different.
But these small changes will certainly accumulate and the pace of change will probably accelerate with more communication and integration. So who knows what will happen in the next 50-100 years.
Welsh was pretty much wiped out as the far more practical use of English press over the centuries. About 50 years ago there was a political movement to re-introduce it, laws were past to ensure that government communicated in Welsh on request , roadsigns were bilingual, and Welsh was taught in schools (which is probably just as useful as French being taught in schools).
Language is the major barrier of freedom, I can theoretically get a job and move to Dublin, London, Berlin, Rome, Cadiz, Porto, Budapest, Taliin or Athens. In reality the language prevents it in most cases.
In 100 years time we could either live in a fuedal society where you can live/work in a small area owned by a local baron who reports to an international mega corporation, with international style communications in a language nobody knows - just like 14th century England and Latin, or we could have a free borderless world where there is fictionless movement and communication. I hope technology will enable the latter before the former entrenchs again.
