Blockchain is called a technology that will change us just as the Internet has changed it. blockchain ideologists claim that it is about to lead humanity to a ultra-modern world where there is no theft and deception. how will this happen? Will the blockchain become the Savior of our world economy or its killer? If the blockchain is tightly integrated into our lives, the unemployment rate will increase, and on a huge scale. And this can lead to a large percentage of poverty among the population. Will the world economy sustain such a large number of unemployed, or will society be further divided into social classes.
Blockchain is not the only thing behind uninployment and such things. If you want to work you can as there is always some way to earn money. Thing is that with robots and computers taking the ordinary jobs. Just take a look at the most boring jobs first was assembling lets say cars, and then robots took over. Now even some markets in my town have cashiers where you don't interact with person, where cash register is simply a machine etc.
So how time passes by we succesfull automate some proccesses because we can. At the end of the day you have the idea of universal basic income for the time when machines take over.
It can't really take us to the world with no theif and diception, those will exist no matter where you go and what time it is.
I think that you have msiunderstanding of what blockchain is actually. It is like an decentralized data structure or database that can't be changed and money like bitcoin can be "saviour of our economy" but for that to happen it's still far far away from it.
