It's a bit weird to jump to the conclusion that things like credit cards will become obsolete, but then I guess at a certain point - probably around the same time the CBDC's are mainstream - then we might have transitioned to only storing debit/credit card apps on our phones anyway. A digital currency does not somehow replace these payment processors, these payment processors can use any digital currency and would likely transform themselves into a trusted exchange. It's likely that hackers would be much more aggressive at targeting home computers in a society that had transitioned to a "digital wallet at home" type setup and most people would feel more comfortable storing their money with well positioned and skilled experts.
Payment processors would effectively become custodians of your CBDC holdings. Perhaps, they will charge maintenance fees and whatnot to stay in business. The thing is, the world is becoming "digitized" at a fast pace. Physical assets will no longer be relevant. They will become a thing of the past.
Like I've stated previously, the climate change agenda will completely remove the need for plastics and paper to help protect the environment. This is the future whenever we like it or not. My guess is that credit/debit card companies will only issue virtual cards after the rollout of CBDCs. Old generations are not quite fond of digital payments, so it's going to take a while before the transformation is complete. Who cares about Fiat anyways? As long as we have a decentralized cryptocurrency like Bitcoin, there should be nothing to worry about.
