I think cars will fly, probably I will be dead to see it but I really hope it hapens because it will be a huge help. Not all cars will go by air, I think that some of them will still go on the streets because it will be a mess if all of them were in the air.
Scientists are saying that we will be able to go to other planets some day, I think this will happen and it will be great because we will discover hundreds of things.
I think students will learn with laptops, tablets... Some schools are already doing that. We won't need pencils or paper.
As you know, Coronavirus has stopped the world, factories had stopped too that means that the pollution has been reduced, thanks to that the earth is so much better and I hope that this will stay this way for the future.
Sadly racism and sexism exist. Now we are fighting against it, I hope that our future generations don't have to experience that. We are all the same and maybe they will understend it better than us.
