any examples? At this point, it seems everything has been already build (saying as a person who only worked in IT and don't have visibility on other industries, but would like to get some)
Everything was already built in 2005. It turned out that the more things are already built, the more things people build, and that requires building even more things on top of it...
Are you saying you think we are living in the best possible world and you see nothing to improve? Many people feel otherwise, and they are the ones launching companies.
