What will the world be like in 1000 years?

Please nobody say that humans wont be here. Of course we will we lived through everything think about the black death it killed half of europes population but were still here. so wat do you think it will be like? do you think we will still celebrate holidays like christmas, easter, hanukkah, etc? do you think that cities will have the same names ( like new york will still be called new york) do you think there will still be the same languages like english, french, german, spanish, italian, chinese, polish, etc. Do you think there will be another 'age of exploration except we will go to different planets? who do you think will be the worlds superpower? will we have hovercars? And do you think there will still be culture (do you think there will still be the old towns in europe, will people still eat rice in asia, will there still be flea and food markets) and lastly do you think we will descover aliens?
