And you imagine that technology does not stand still, they are constantly evolving, and sometimes it's scary to imagine what will happen in 5-10 years. I think blockchane will radically change the world.
In fact blockchain is already changing the world. I think that on the basis of the blockchain, another technology will allow to optimize the current tasks even more.
I will say this: it is difficult for us to imagine what tasks and problems will be faced by a person in 20-50 years. And maybe we even will not even consider the problem. After all, if my grandmother knew all this, she would say that we are crazy.
Your grandmother just does not know what blockage is. Try to explain to anyone this technology: friends, relatives. What kind of technology is it. They will consider you a fool? or do not attach importance, just another technology.
