I think that there would be a lot of improved things and even new inventions in the future, a century from today. A few examples are more powered technology, faster ways of fixing different things like buildings, cars and even improved medicines and medical needs. Also transportation could be super advanced in the future. There could be doors in which they take you to another part of the universe in just one second flat or planes with increased speed that does not hurt passengers. And probably by then, a little bit of time travel can be possible but only one day back in time. Robotic Technology can be advanced in the future as well. For example Robots can undergo sea missions and investigate sea life. Or can be sent to find very rare gems underground. Food is also another thing. Maybe a really special fertilizer can be made for the food to grow really quick in just two days. These are the very interesting things that could happen a century from now, and billions of more ways to make life easier.
