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. 
In my country, specifically the area where i stay, if you visit 100 shops or supermarket around that area, you can make your payment via bank transfer or a payment processor that you will need to scan the shop Payment QR code and make payment. Credit and debit card is still in use but lots of people are paying via tranfers which is making credit and debit card to gradually become useless. There's this my X girlfriend, she doesn't have a debit card, every payment she make is via tranfers.
