In these matters, I always try to keep in mind that technologies aren't themselves disruptive; customer choices are. It'll be interesting to see what customers choose in the years to come.

Does that imply that some day users would be able to pay using Tempo?

I don't think that customers or businesses should see Tempo very much. In the success case, Tempo is a platform like SWIFT or ACH that others employ behind the scenes to orchestrate transactions. "Decentralized, internet-scale SWIFT" isn't exactly the right analogy (there are clearly lots of differences), but it's not totally wrong either.

Why are businesses finding crypto easier/faster/better?

Yeah, I think this is the natural follow-up question. The answer differs a bit based on the use-case, but there are a few common reasons:

* Instant on-chain transfers avoiding trapped liquidity. If you're transferring money from financial institution A to institution B, and the transfer takes a day, you're either slowed a day in taking the next step or you have to somehow cover that float. Depending on your movements and their predictability, that can require big buffers.

* Fees that are lower than cards. Card payments are instant, which is often valuable (and superior to many bank transfers), but card transactions are also expensive relative to stablecoins. (And while card authorization is instant, settlement is not.)

* Reliability. This sounds funny, but, when sending money between countries, there are many more manual processes involved at the associated financial institutions than one might think. Money is frequently just... lost, and humans are required to hunt for it. (We see this all the time at Stripe.) Crypto is punishing if you make a mistake, but, if you do things correctly, reliability is all-but guaranteed.

* Fewer currency conversions. Wholesale FX for major currencies is very cheap, but minor currencies can have bigger spreads, and the actual fee incurred by a regular customer (e.g. with their bank) can be significant. Stablecoins often make it possible to skip conversions that would otherwise happen.

* Access to USD-based functionality. The US is the world's most sophisticated financial services market. Having a stablecoin means "having an on-chain asset", but it also typically means "having a USD asset", and a lot of major parts of the ecosystem (e.g. US equities and credit markets) primarily, or only, deal with US dollars.

Acknowledging the obvious, a reflexive answer frequently invoked here is "it's regulatory arbitrage", but I think this is some combination of misguided and incurious as an explanation. First, stablecoins are now formally regulated in the US (with the GENIUS Act) and in Europe (under MiCA), so their use is now very explicitly regulated. Secondly, it implicitly assumes that the only reason one would seek an alternative to the traditional ways of doing things is because someone is doing something illegitimate. I think this usually indicates a lack of understanding of the challenges, complexities, and costs associated with high-volume cross-border money movement. Indeed, and somewhat ironically given the claim, one of Bridge's large customers is the US government.

There are lots of crypto skeptics on HN (and we ourselves were disappointed with crypto's payments utility for much of the past decade), so it might be interesting to share what changed our mind over the past couple of years: we started to notice a lot of real-world businesses finding utility in stablecoins. For example, Bridge (a stablecoin orchestration platform that Stripe acquired) is used by SpaceX for managing money in long-tail markets. Another big customer, DolarApp, is providing banking services to customers in Latin America. We're currently adding stablecoin functionality to the Stripe dashboard, and the first user is an Argentinian bike importer that finds transacting with their suppliers to be challenging.

Importantly, none of these businesses are using crypto because it's crypto or for any speculative benefit. They're performing real-world financial activity, and they've found that crypto (via stablecoins) is easier/faster/better than the status quo ante.

Mathematica's speed (or lack thereof) rarely bothers me; personally, limitations caused by not having the turtles go all the way down tends to be a bigger issue.

With that said, I find the lengths to which Mathematica takes pattern-matching fascinating. There's something beautiful about having

  Fold[f, 0, Range[1, 5]]
evaluate to

  f[f[f[f[f[0, 1], 2], 3], 4], 5]
