The mobile phone industry was also deeply entrenched back in 2007, it still got disrupted wildly within a few years with the iPhone.
If Crypto is so revolutionary, it should have resulted in radical changes within the entrenched financial industry. All we've seen is regression (Stripe supported bitcoins from 2014[0]-2018[1] for eg).
That's what happens when you only look at Stripe. smh.
Pretty sure every major financial institution is buying crypto because it's obviously superior to the dying and corrupt printer and fax system.
