Do you think the tech here includes blockchain and crypto?
Not really, though I'm pretty sure banks are figuring out if it would be profitable for them to enter the crypto space and possible ways to do it.
Banks are not stupid, and they're not going away despite CNBC's use of the media-buzzy "extinction phase". I don't claim to know much about what's happening in the fintech world, but I'm confident that banks will figure out a way to integrate new innovations into their businesses. They have the money, power, and experience to do this.
Peoppe will still choose to use blockchain.
You say that as if bitcoin or blockchain technology has been adopted to an extent that people are going to abandon traditional banking. This isn't true.
The conventional banks should think of a way to harness the blockchain into their business else it will extinct.
You better believe they're already thinking about ways of doing this, although I don't think lack of blockchain adoption by banks will mean their doom. Again, bitcoin and blockchain have not been adopted by the masses to the extent that people posting in this thread seem to think they've been.
Bank is an additional source for the government to make extra money and it will not perish by the blockchain. There might rather be a change in policies that will give way to both the economic units to go with harmony side by side.
