Well, think about Tesla motors and the rest of the car industry. Tesla is not saying you guys suck go broke, on contrary Elon is even sharing his patents. The key is disruption as other innovative orgs are doing, like for example Uber with taxi industry which already existed for long time. Facebook and social media (not that I agree with the methods but they changed the social media game) and I could keep going, Google, Apple....
So now societies need better currencies, better public payment methods, the internet is everywhere, paypal is private, visa is private, mastercard is private, SWIFT is private and all of them where good in the past.
Banks are for sure reluctant to change. They argue why change? we make lots of money, we take everyone as suckers, we have strong ties with governments. I'm quite sure that one of the big social incoming transformations is gonna be the separation State vs banks as it was the same between the church and govs in the past.
I'm just saying that if banks collapse they will take everything down for sure, but if they adapt they could transform themselves to something better suited for all. Might be wishful thinking but cryptos will definitely play a role in this and Worldcoin is fit for the job.
