I give nearly zero credence to "opinion" from artificial intelligence. If there isn't a citation of a verifiable data source the information is not to be trusted in my view.
Some people find card or digital payment convenient, others follow incentives, still others stick with habit. For example, I still prefer to pay bills and contributions by check sent through postal mail. However, some merchants reduce my bill if I sign up for automatic payment from my bank account and I sometimes take advantage of that. I often use an Amtrak Mastercard (balance paid off every month) to build up points for free train travel, rather than using cash or writing a check. My bank pays interest on my checking account balance each month I have at least 15 debit card transactions and I make sure that I do. Increasingly merchants aren't accepting checks because their validity can't be verified at the time of a purchase. On the other hand, I may boycott a merchant who doesn't give me the option of paying by cash. "Back in the day" if one was at a parking meter or a pay-for-parking lot and didn't have cash or exact change they may have to over pay what was owed or risk car impoundment for not paying. Debit/Credit carts and digital technology eliminate that problem. Of course, the technology costs money and while the cost may be hidden one will pay for it through the cost of the service.
Debit and credit card transactions cost the payee a service fee. My dentist a few months ago said there would be a 3% surcharge for paying by debit or credit card ... I returned to writing him a check. Some shops won't accept card payment for sales under $5.00, or they add a surcharge to those transactions.
The bottom line is that there will never be a "perfect system" this side of the Second Coming, but my BS meter goes out of range when some say we will be forced into a "cash less economy".
