I think that the existence of blockchain is to make up for the shortcomings of the Internet, but it cannot replace the Internet. However, with the development of the Internet, the areas it will involve in the future will be more and more wide, so the industry is very promising.
I think you have no idea what block chain is all about,how can it make up for the short comings of the internet 
It is simply a place where you store or record the data and secure it using cryptography and it has a time stamp and a transaction data and by design the block chain cannot be modified and this can be used in a variety of business and is a promising technology.
