We previously launched the Readwise CLI, which has similar functionality but only works in the terminal.
For terminal apps (eg Claude Code, Codex CLI) the CLI is still best,
but for any other AI app: the MCP server now should work seamlessly 😎

Smartphones are not the explanation for the recent decline in fertility. Instead, they are an accelerator of deeper forces already at work.
Let’s start with the facts. Fertility is falling almost everywhere: in rich, middle-income, and poor countries; in secular and religious countries; and in countries with high and low levels of gender equality.
The decline accelerated around 2014. So, no country-specific explanation will work unless you are willing to believe that 200 distinct country-specific explanations arrived at roughly the same time.
Smartphones look like the obvious candidate: the first iPhone was released in 2007, and global adoption has been astonishingly fast.
Economists understand the first major decline in fertility in advanced economies, from 6 or 7 children per woman throughout most of human history to about 1.8, that occurred between the early 1800s and roughly 1970, well before smartphones. The main drivers were a sharp fall in child mortality (effective fertility was rarely above 3 and often close to 2) and the shift from a low-skill, rural agrarian economy to a high-skill, urban industrial one. We have quantitative models that fit these facts well.
Country-specific factors mattered too, of course. Proximity to low-fertility neighbors accelerated Hungary’s decline, while fragmented landowning structures accelerated France’s. But these were second-order mechanisms.
This is also why most economists long considered Paul Ehrlich’s doom scenarios implausible. We forecast that fertility in middle- and low-income economies would follow the same path as in the rich, probably faster, because reductions in child mortality reached India or Africa at lower income levels (medical technology is nearly universal, and most gains come from handwashing and cheap antibiotics, not Mayo Clinic-level care). Much of what we see in Africa or parts of Latin America today is still that old story.
But in the 1980s, a new pattern appeared. Japan and Italy fell below 1.8, the level we had thought was the new floor. By 1990, Japan was at 1.54 and Italy at 1.36.
This second fertility decline began in Japan and Italy earlier than elsewhere, driven by country-specific factors, but the underlying dynamics were widespread: secularization, an education arms race, expensive housing, the dissolution of old social networks, and the shift to a service economy in which women’s bargaining power within the household is higher. The U.S. lagged because secularization came later, suburban housing remained relatively cheap, and African American fertility was still high. U.S. demographic patterns are exceptional and skew how academics (most of whom are in the U.S.) and the New York Times see the world.
My best guess is that, without smartphones, Italy’s 2025 fertility rate would be about 1.24 rather than 1.14. I doubt anyone will document an effect larger than 0.1-0.2. Italy was at 1.19 in 1995, not far from today’s 1.14. The TFR is cyclical due to tempo effects, so I do not read too much into the rise between 1995 and 2007 or the decline from 1.27 in 2019 to 1.14 today. The direct effect of smartphones is not zero, but it is not, by itself, that large.
Where social media, in general, and smartphones, in particular, matter is in the diffusion of social norms. What would have taken 25 years now happens in 10. Social media are not the cause of fertility decline; modernity is. But they are a very fast accelerator.
That is why social media are a major part of the story behind Guatemala (yes, Guatemala) going from 3.8 children per woman in 2005 to 1.9 in 2025. Without them, Guatemala would also have reached 1.9, just 20 years later.
Modernity, in its current form, is incompatible with replacement-level fertility. By modernity, I do not mean capitalism: fertility fell earlier and faster in socialist economies than in market economies. Socialist Hungary fell below replacement in 1960, and socialist Czechoslovakia in 1966 (both experienced small, short-lived baby booms in the mid-1970s). By modernity, I mean a society organized around rational, large-scale systems and formalized knowledge.
Countries will not converge to the same fertility rate. East Asia is likely stuck near 1, possibly below, given its unbalanced gender norms and toxic education systems. Latin America faces the same gender problem plus weak growth prospects, so I expect something around 1.2. Northern Europe has more egalitarian family structures and might hold near 1.5. The very religious societies are probably the only ones that will sustain 1.8.
All of this could change with AI or changes in population composition. We will see. But on the current evidence, deep sub-replacement fertility is the “new new normal.” Unless we reorganize our societies, better learn to handle it as best we can.

I’m an appellate court judge with 29 years in the law. I’ve read more briefs than I can count.
Strong arguments are crucial.
But they’re not enough.
If you overtax the judge’s brain, you’re less persuasive.
Here are three tips to write for the judge’s brain instead of against it. Thread. 🧵

Here’s a simple way to get unstuck when you’re worried, overwhelmed, or overthinking a decision.
Ask yourself one question:
What kind of thing am I dealing with?
Most issues fall into one of three categories.
1. Settled Things
These are things that have already been decided.
Your birth family.
Your nation of origin.
Your height.
Your past decisions.
Your upbringing.
Things you did.
Things done to you.
Some of these things were decided by your own past actions. Others were decided by God’s providence. As Paul says in Acts 17:26, God determined our appointed times and the boundaries of our dwelling place.
You can’t go back and change these things.
So the question is not, “How do I undo this?”
The question is, “Does this have any bearing on what I should do now?”
If not, leave it alone. Don’t spend your life fighting settled things.
2. Action Things
These are things you have some real control over.
Your diet.
Your exercise.
Your spending.
Your work ethic.
Your attitude.
Your friendships.
Your theological knowledge.
Your presentability.
Your habits.
Your skills.
These are your controllables.
You may not control everything about your health, finances, relationships, or future. But you usually control more than you think.
So if the issue falls here, don’t overthink it.
Take direct action.
Start small if you have to. Make the call. Go on the walk. Open the Bible. Apologize. Apply for the job. Pay the bill. Clean the room. Do the next faithful thing.
3. Prayer Things
These are things outside your direct control, but not outside God’s control.
The economy.
The weather.
The housing market.
The availability of a suitable spouse.
Other people’s choices.
Timing.
Open doors.
Closed doors.
You can’t force these things. You can’t grab the steering wheel of providence.
But God can act.
So you take indirect action through prayer. You ask. You wait. You prepare. You remain faithful. You do what you can do and trust God with what only He can do.
So ask yourself:
Is this settled?
Then accept it and learn from it.
Is this actionable?
Then do something.
Is this outside my control?
Then pray and trust God.
This is a simple framework, and yes, it’s a little reductionistic. But that’s the point. The goal is not to explain every complexity of life. The goal is to get you unstuck.
Most people waste too much energy trying to change the past, control what belongs to God, or pray about things they simply need to obey.
So categorize the issue.
Then act accordingly.
Accept what is settled.
Act on what is yours.
Pray over what belongs to God.

Anthropic just published their official Claude Code best practices.
Presented live in San Francisco. By the engineer who built it.
Cal Rueb, Member of Technical Staff at Anthropic, took the stage at Code with Claude on
May 22, 2025 and shared everything Anthropic's own engineers do internally that most users
never figure out on their own.
This is not a third-party breakdown. Not a community guide. Not someone's opinion pieced
together from Reddit threads.
This is the official playbook. Straight from the source.
Cal shares how he became completely addicted to Claude Code, downloading it over a
weekend, building a note-taking app, and carrying his laptop everywhere watching it work.
Then he breaks down exactly how Anthropic's internal teams use it to ship production code
faster than any workflow they had before.
In the video he covers:
1. How to set up Claude. md so Claude always knows your codebase
2. Why planning before coding changes everything
3. How to manage context so performance never degrades
4. The parallel session workflow Anthropic engineers use daily
5. Security, permissions, and how to stay in control
Anthropic's internal testing found that unguided attempts succeed roughly 33% of the time.
With proper planning and structured workflows, that number climbs dramatically.
The gap between developers getting mediocre results and developers shipping 10x faster is
not the model.
It is the workflow.
This video is the workflow.
