With language being changed so much?

Question

Will we soon not be able to communicate any more RB right back etc.

How long will it take for our language to disolve into a puddle of mud?

Answer 1

one more generation I think  or about 75 years

Answer 2

Each young generation has a finite set of words which they claim as their own and attempt to propagate into the general vernacular.

However, formal language tends to remain constant, and, thus, relatively untouched by the current slang.

So, feat not.  The idk's will remain, but most of the rest will be lost to all but a select few.
