In my opinion our lives will be more relaxing and healthier in the future. We won't create any pollution, and scientist will create super-robots which will do difficult jobs. We might have more time for hobbies.
I think it's important that we colonise space. If we don't live on other planets we have don't enough food or space for all of the people on Earth.
In general I feel optimistic about the future. I believe that people will have more technologies and live in peace.
