I think that life in 2500 will be absolutely another. Our world develops very fast, for example 10 years ago we knew nothing about an internet and we could live without it. And in this short time span we may say that everything is changed.
I guess in 2500 people will make robots like a real human who will help us with housekeeping. In every corner of the world everyone will live almost on tne one level. I hope in 2500 everybody will go by bike or on flying ecological cars. Apple will produce a new iphone500. Also humanity will try to save nature that we destroy a lot of years.
That is all my imagination about our future life in 2500.
