No one will argue with that internet has affected our lives, but the only thing it has literally changed is how we get information. To find anything you need no more than a few seconds, instead of hours spent in libraries, books or tv. It's already pretty amusing, the most important factor however, is sequence from having an opportunity of fast transfer of information. Using internet you can create any platform, i.e. video hosting or payment system. What you've just read seems to be very obvious at the moment, but when the global network appeared no one believed that such useful services can be ran there. Nowadays we're about to have another technical revolution which is going to be blockchain based.
As a powerful technology blockchain first appeared a decade ago, but even after such time we do not understand the true power of it. Despite the fact blockchain is just a distributed database, giant amount of services can be built on it. Distribution makes it fully uncontrolled and unregulated by no single person or even government: video uploaded on a video hosting can't be deleted (one of the most popular of such services is Viuly which used to be an ICO project, but is a very popular platform right now), while transaction in payment system (which is called cryptocurrency) can't be canceled.
How you see blockchain can affect any sort of service we already have or even create a new type of such, just like the internet did one day. What is more, this technology can change the internet and made it independent from laws and rules as it was during the first time. It can be found very helpful in countries, where governments are trying to have full control over the lives of their sitizens.
In case you're sceptical about how useful blockchain is, here is a true story that will change your mind:

For the last few years amount of ICO projects aimed at the internet has been growing, and a big part of them gain success. Hopefully the internet is getting better and better and one day we will find out that internet is no unregulated and that we can live the way we want to.
