At this rate, Idiocracy the movie will make us look intelligent because in that portrayal, we could understand their language.
In our reality, we are messing up our language either deliberately, sarcastically, jokingly, accidently, ignorantly or unknowingly that in a hundred years we won't be able to understand future generations at all.
In the future, not only will we act stupid and live in a broken down global environment that we destroyed, we'll also sound complete stupid as well.

All languages always, have evolved at rapid rates, as long as they're used. If you went back in time to, say, the 1600s, you would sound stupid. If someone from the 1600s went back to the 1200s, he would sound stupid. If you went back to the 1200s, nobody would understand you.
This is not a new thing, it is how our languages work.
