Do you think credit/debit cards will still be a thing after the launch of CBDCs? If not, why? Will payment processors like PayPal, Visa, and Mastercard survive? Your input would be greatly appreciated. Thank you. 
I think they will tend to disappear, and in fact they are already changing. The ones I have now don't have a space to sign on the back like they used to. With CBDCs and mobile phones, I think they will disappear.
