75% energy save to make a room temperature expresso. I am ok spending a bit more energy to have it warm.

Pix resolved this by allowing email, phone number, tax ID or random generated key as an identifier.

SEPA is a banking infrastructure layer and it is not consumer focused. Also, only ~60% of European banks adopted it. While Pix was mandatory for all banks to adopt and 80% of Brazilian population already used it.

It is not the same. Mercado Pago is a product from Mercado Livre and charges at least 0.8% per transaction.

It will not take long. Banks are already offering products with credit on top of the Pix. Furthermore, contactless Pix is now available in Android phones. If we look from the financial and usability aspects, Pix will continue eating the credit card market share.

I didn't know Thailand and Malaysia had similar systems, though. I hope the example spreads! Creating a competitive infrastructure and product is an interesting way to deal with monopolies.

Brazil central bank introduced Pix a few years ago. It took over the country as the public basic infrastructure for money transfer. Totally free and instantaneous transactions between people and companies, available to all banks.

Then, just last week, the US presidency launched an investigation considering Pix an unfair trade practice against the US.

Actions like that may show the current direction of the US government is aligned on preserving status quo. But still, I wonder how impactful a public digital infrastructure for the dollar would be.

Exactly, X userbase is going down. So less than zero sum.

Nice horizontal scroll.

Due to its size and historical reasons, we have regional power that many times could try to benefit from physical voting receipts. It was common for local leadership to offer favors in exchange for votes.

You don't know Brazil. The system's speed reduces the change of undemocratic action by those in power. Since 1889 Brazil has faced ten coup trials by the army (eleven if we consider what happened on 8th Jan of this year), and six were successful. Our current system's new republic is the most prolonged period of political stability (and the most successful from the socioeconomic perspective) in the country's history, largely due to our election system. Australia, New Zealand, and other countries have different histories and, therefore, different needs.

Everything is auditable. Both civil and state institutions audit the system. It could be better. Making all open-source would be a massive step in transparency. But there are multiple mechanisms:

- random sampling checking comparing digital and printed results (each machine prints a summary of the votes)

- voters receive a number to double-check if their vote was counted (however, they can't see who they voted for to guarantee vote secrecy).

- parallel voting: in randomly selected locations, the vote is cast to a shadow voting machine and computed in parallel to identify discrepancies.

- public software and hardware inspection: any institution, civil or not, can inspect the entire system. The army (yes, the one that is proud of the multiple coups) was acting to reduce the system's credibility and did an inspection and could not find anything substantial.

We can't compare different countries without a historical and social lens. NZ electoral system in Brazil would be a disaster.
