Well, I'm predicting the Lord's Imminent return in about 25 or 26 years.
When He comes He will reign on earth for 1000 years.
So, I would say that in 100 years earth life will be beautiful - beyond our current comprehension I would say.
Firstly, we know that "the lamb shall lay down with the lion" and "a child shall play on the hole of an asp".
We also know the original universal language was lost 1000's of years ago.
Personally, if I'm here or resurrected here, I will be walking, talking, playing and dining with the animals, as well as all of our fellow-beings!
Does that give you some idea of my vision??
