Language in quick decline

No it's not happening.  Yes it is.  The Navajo Times reports the Navajo language is in decline.  ("Data shows huge reduction in Diné speakers")  The article predicts that in 3 years, we will be at 30% speakers, mostly consisting of the older generations (over 40). I wonder "how it will be in 2050?".  2070?  That has always been the American dream.
