I didn't read the whole article, but I don't believe this could be true. If it is true there would be an enormous market for it to act as a mediator in any payment dispute and then decide whether to reverse a transaction. (Each side could offer whatever arguments and evidence it wanted.)
This would solve the huge problem with crypto currencies that there is no repudiation for fraudulent transactions (they can't be reversed if they turn out to be fraudulent.) But an AI can't actually do this and back up a currency with a dispute process around it, that's why it isn't being done.
Here I roleplay a dispute between a merchant and a buyer:

As you can see, it finds in favor of the person who wants to reverse the charge, but this means the buyer can just rip off any business, get anything they want for free and literally never pay for anything by just reversing every transaction. What the AI judge should have done is look at the total amount of business that the business does and whether it has any other disputes, because if the total amount of business is high without any disputes then it is a legitimate business, but if everyone is disputing it or it tried to inflate its ratings with a bunch of low-value items and then shipped rocks instead of a high-value item then it is a scam merchant. Besides this, changes of ownership also matter (a scam merchant who will ship rocks can buy an existing long-standing merchant for their credibility).
Overall, a blanket reversal without looking at the merchant to verify that it is fraudulent is not really good adjudication in my opinion and if the AI were judging all these cases then consumers could just defraud every business and no business would use that form of payment and dispute process since consumers would abuse it to get everything for free.
This shows that AI really isn't ready to adjudicate real cases, and this case is far simpler than cases that make it to the Supreme Court.
