> Do corner stores (small informal convenience stores) in Brasil usually accept PIX? I assume they all cash-only.

Pretty much every single one I've always been to. From the smallest one-person street corner popup shop to the biggest shopping mall boutique and outlets, virtually everyone accepts PIX payments. Its just better - its one of those "you gotta use it to understand" things.

Anecdotally: I've even gave some cash to homeless people on occasion using PIX. This may seem weird, but in Brazil, you must have a bank account to be able to subscribe to any sort of government benefits, and since its free, pretty much everyone has an account and therefore can receive PIX payments. Its also safer, since you're not carrying cash with you, and even if you're somehow forced to transfer, there are ways to monitor and reverse transactions (so called MED).

Of course, there's been a few incidents over the years where some concerned citizens would not accept PIX payments because "the government will know what you're spending on" (in contrast to, say, credit card operators, where apparently the "right people" would know what you're spending on...).

There are some criticisms of the current system, which is fair, but most that I have heard are ideological in nature or some sort of foreign defaultism.

In Africa they've had this since ~2005 with the Mpesa system. It basically transfers cellphone credits as payment. In certain regions everyone with a dumb phone was hooked up and you could do anything from buy a coconut from a guy on the side of the road to pay your taxi driver to pay at the supermarket.
