Serious question: Why do doctors change their practice so much based on one case study? Surely, even if there isn't any malice, a doctor can make a mistake?
I wondered this too after reading the original New Yorker article a few weeks back and was quite surprised.
However, the article also made me think that once a practice is adopted it’s hard for it to change even if the evidence support changing. (Which is how I expected it to be from the outside)
I figured there was some context that I was missing as to why some things are quicker to adopt and others less so. Maybe because adopting this change was seen to be “saving” lives by being more cautious about the how medicines and feeding interact - and reverting the change is “risky” in case there is truth to it.
Case studies are used in medical decision making only when there is no better form of evidence available, or there is a gap in current evidence. It is not the first place to look
We don't ban bridges, but we do install suicide barriers, emergency phones, nets on the bridges. We practice safety engineering. A bunch of suicides on a bridge is a design flaw of that bridge, and civil engineers get held accountable to fix it.
Plus, a bridge doesn't talk to you. It doesn't use persuasive language, simulate empathy, or provide step-by-step instructions for how to jump off it to someone in crisis.
Fun fact: Weird Al has spent the last 2 years finding comments on videos of his songs that say "Is this AI-generated?" and responding "It's Al-generated!"
1. A payment processor for users to turn money into tokens
2. A payment processor for news sites to turn tokens into money
3. A software provider to handle the actual microtransaction part of this (unless they want to learn how to become software developers themselves)?
It seems to me like all the blockchain does here is to make it so this transaction needs 3 software providers instead of just one!
The argument I had originally heard was "the transaction costs of credit cards is so high, we need a system that works for many tiny payments. But of course, most of the cryptocurrency transaction fees are still pretty high, and a dedicated "tiny transaction" company would presumably be able to offer the same service for less cost than a distributed equivalent.
Transaction fees for bitcoin sent via the lightning network (which is a layer 2 solution) are in the "less than a cent" category and are settled in a few seconds. This is not fiction, this is i.e. how Trump made his for-the-cameras bitcoin payment during his campaign.
Lightning isn't even a good solution for most diehard bitcoin users. It's a failed project.
It would take 27 years to onboard every internet user to the lightning network unless you start adding level 3 aggregators and then at that point you lose all the benefit of it being on chain at all.
It would take almost 2 years just to onboard every American assuming during that time there were zero other bitcoin transactions. Then you need to add the fees for the on and off ramps to the individual transaction fees to get the real cost per transaction noting that these would go up quite a bit as the competition between lightning and non-lightning uses of the transaction space would drive prices higher.
The throughput is arbitrarialy limited by bitcoin's current block size, which hasn't been increased since satoshi's era.
Most cryptocurrencies have an adaptive block-size mechanism which allows the blocks to grow to a reasonable size which could facilitate such an onboarding of users. So it isn't a technical problem, it is just a question of bitcoin's current leadership, which is controlled by companies like blockstream.
People have been debating the blocksize for a very long time now and there doesn't seem to be any large desire to change it so while the ability to increase it exists changing anything that fundamental about bitcoin seems to be a non-starter and while that is true lightning is pointless as a solution for the masses.
Even if you increase the block size 100x though you're still not improving the numbers much since my very generous numbers ignore activity outside of lightning and assume a single on chain transaction for every user and a perfect network.
Maybe your understanding of lightning is wrong here. Yes you open channels, and transactions in lightning need open channels, but you do NOT NEED to open channels for specific transactions. You open channels once, and transact over them for years. I run a lightning node with more than 15 channels (each to different lightning nodes) that are all older than 1 year (I route payments, so I have way more channels than needed). You can batch-open channels, i.e. I could have opened all my 15 channels with a single on-chain transaction. Taproot update would make those "commitment transactions" onchain way smaller (in byte) than needed to in the past.
Once channels are open, the users on the lightning network can transact back and forth without any new channel opens/closure and thus no on-chain settlement. Hence: Throughput in lightning is not at all limited on the bitcoin transaction throughput.
You mistake is, you overestimate the amount of people who want to be self custodial. You don't need to onboard every human being in the world on-chain.
Given the US example that would be several years in the absolute best for lightning case to onboard even 5% of individuals. Lightning is doomed from the start.
And if you don't care about self custody then the overhead of using a blockchain is a waste.
It is not black/white. It is okay to have the freedom to become self-custodial anytime, but not everybody needs to transact in self-custody all the time.
Taproot was another major step that enables lightning upgrades in future versions (such as zero-fee channel opens) that is barely discussed. The number of X years for onboarding Y amount of people is not accurate, as it disregards all major developments of the last 5 years.
You need enough users for providers to bother making it an option to pay with so it really is black and white. You might get a few niche providers offering it as a payment method without a critical mass of users but most companies aren't going to invest time and effort into implementing a payment system a tiny percentage of users have access too and if I need to trade money with my friends the low % means that in the vast majority of cases they aren't going to have lightning available either.

And yet the conclusion is about pink noise vs silence. We may have a new textbook example of HARKing right here!
> The results, the researchers said, suggest not only that earplugs—which are used by as many as 16% of Americans to sleep—are likely effective, but also that the overall health effects of pink noise and other types of broadband noise “sleep aids” need to be studied more thoroughly.
