One of our greatest failings as a society is our abject failure to teach people finances. It's as critical to our lives as breathing, eating, and crapping, yet the vast majority of people can't even count change let alone understand credit.
Incidentally, anyone telling you BNPL is good for you is trying to milk you. Please just don't and stick to cash/debit or good old credit cards, for your friends' and family's sake if not yourself.
