Maybe instead of asking this, we should ask the cryptocurrency enthusiasts what area of technology won't be dropped-and-replaced by blockchains, because so far it seems apparently applicable to every single use case in every single industry... By the way, did you guys hear this thing is an immutable ledger?
There is very little overlap between cryptocurrency enthusiasts and those who think blockchain technology will take over everything.
Do you really believe that? Because from the outside, it seems that the only people talking about "blockchain technology" are those who have a significant amount of money invested in it.
This article is a blockchain banking service saying, "hey, other people should use this solve-all technology that is definitely the future too!"
The people who are into "blockchain banking" are not actually into cryptocurrency. Cryptocurrency is about decentralised, trustless, permissionless, peer-to-peer networks. "Blockchain all the things" is decidedly not.
I acknowledge that this can be hard to see from the outside.
Edit: And at risk of "no true Scotsman"... the people talking about "blockchain technology" are not cryptocurrency enthusiasts.
