Is there any reason for such claims or are you just dreaming out loud?
This idea that blockchain is gonna be used everywhere doesn't make much sense.
Blockchain is a slow and expensive database. Unless you have a very specific problem that blockchain will solve, it shouldn't be used. In most cases, blockchain is not applicable to the problem.
I so t think governments are going to use it everywhere to become more transparent. There are other way to become more transparent, which are less expensive.
I somehow agree with this idea and it looks like there are no references to support his claims.
Yes there are a lot of benefits we can get from this new technology but on the other hand there are a lot of things to consider. If this will apply to a certain company that sells goods, it will be purely efficient and makes the transactions very fast. While in the side of the Consumer, it will be easier too for everything will be automated once they order a single Item. However, there are security or privacy issues that should be keep in mind. Although every node has a copy of every transactions they should implement limited access to the consumer for they are not required to know every information.
Lastly, blockchain technology requires more power as it solve complex problems. This can be a burden to some countries that has larger price range for electricity.
This is not easy as many think. Though blockchain was powerful, there are some things to consider.
