One thing i know for sure is that the semantics will change in the year 2117.someone speaking English then will not understand our English unless they are historians and so gies for most languages. I would also hope an accelerated technology much like the computer age (pc has been around for like 35 yea s and see how much it has fueled interms of change) will emerge and take humanity several folds ahead of what we predict at this moment.
For now whatever we predict might be exaggerated or the opposite.
Yes definitely.
English has evolved a lot so I wouldn't be surprised if they speak a different "version" of it in the future. Thanks for the comment!
