It's probably that people who can't walking nowadays they can do it in the future.
Kinds of families are possibly going to change.
Families with only one member will rise so we will have smaller houses but it will be very comfortables.
Unfortunately our food will change too.
We will have to get used to fast food and packed food.
You will find all kinds of food precooked in the supermarket.
Work habits will be different.
A lot of people will work from their house and all of us will have better work rights.
Succeeding predictions on the future is really difficult, but at least it is funny.
