Ray Dalio's interview with Tucker Carlson just went viral.

And he's NOT just talking about market predictions.

Instead, he exposed a dark truth most Americans don't want to admit.

Here are his 7 shocking claims about 'America's new Civil War': 🧵

Microsoft says meeting time has TRIPLED since 2020: typical workers are spending 57% of their time communicating [meetings, calls] with others: 'Today, knowledge work is, quantitatively speaking, less about creating new things than it is about talking about those things.’

Curioso dato

"En Galicia, ya hay más trabajadores tecnológicos, 24.000, que en la pesca, la mayoría en el área coruñesa. A Coruña ahora mismo es la ciudad líder del norte de España, y ya no tiene nada que ver con la urbe provinciana previa a la crisis financiera"

Deutsch's Rule: If it doesn't defy physics, it's possible.

Don't confuse society's current lack of knowledge with its impossibility.

For example, smartphones seemed impossible in the 1800s due to a lack of knowledge.

Mr. David Aldrich has a space nose, his official NASA title and it is his role since 1974.

What does he do? It is to smell every object destined to be part of a mission and place it on a scale ranging from 0 to 4.

This work is truly fundamental because, in the event of unpleasant odors at space altitudes, astronauts certainly would not be able to open the windows due to external temperature and pressure. It is also true that the stench emanating in certain situations helps to understand the state of health of the components of the mission and this is why if an object exceeds 2.4 points it does not leave with the spacecraft.

To underline the importance of the tasks performed by David, NASA subjects him to a 10-smell test every four months to verify that his efficiency is still reliable.

The adoption of cellphones by Keralan fishermen is, I believe, the most stunning example of the contribution of information technology to market performance.

Take a look at this graph for background: in three different regions of Kerala, phones were adopted at different times.
Kozhikode got cellphones before Kannur, who got them before Kasaragod. Adoption by fishermen was fast when phones were finally introduced:
Now look at what happened to the price of fish after phones entered the scene:
The dispersion in prices virtually disappeared! The author of the study wrote about this that:

"Before any region had mobile phones, the degree of price dispersion across markets within a region on any given day is high, and there are many cases where the price is zero (i.e., waste). However, within a few weeks of mobile phones being introduced in Region I, there is a sharp and striking reduction in price dispersion. Prices across markets in the region rarely differ by more than a few rupees per kilogram on any day, compared to cases of as much as 10 Rs/kg prior to the introduction of mobile phones. In addition, the prices in the various markets rise and fall together and the week-to-week variability within each market is much smaller, since catchment zone-specific quantity shocks are now spread across markets via arbitrage. Further, there are no cases of waste in this region after phones are introduced.

"By contrast, price behavior in regions II and III appears largely unchanged after phones are introduced in region I. However, after mobile phones are introduced in region II, prices again become much less dispersed across markets on any given day, less variable within markets over time, and waste is ultimately eliminated, whereas region III again remains unchanged. Finally, the same pattern holds once region III adds phones."

Efficient information transmission enables efficient markets. It's amazing what technology can do.

This actually happened to Evernote. They took the advice of “keep talking to your customers and ship whatever they want” as the only guiding principle for product development. And what ended up happening was paying users liked it, but the product become unintuitive and feature overload for the new user. To the extent that they had to rebuild a version for the new user.

Users don’t always know if they really want something. It’s your job to take the extra step to think on their behalf: whether they really need this. Or can what they ask be done through something much simpler. Or can you solve multiple problems of different users with one new redesign rather than a bunch of changes. The right principle is: “Keep talking and listening to your users, spend the additional time thinking on their behalf what they actually want, and ship that”.

You can travel across the galaxy in a single life-time with one gravity of constant acceleration

Usually it seems like space is so impossibly vast, it's unlikely aliens or humans could ever realistically visit other stars let alone other galaxies.

However, if you can build a ship that accelerates at 1 gravity, constantly, your velocity builds up fast enough to significantly time-dilate the people on the ship, letting them basically reach anywhere you can imagine.

If you do the math, it turns out you can travel 110,000 light years in just 12 years of shipboard time.

And if you want to slow down so you arrive at your destination not traveling at the speed of light? Flip the rocket half-way, and you can still get to the center of the galaxy in 20 years of ship-board time.

And you can get to Andromeda in 28 years ship-time

* People ask LLMs to write code
* LLMs recommend imports that don't actually exist
* Attackers work out what these imports' names are, and create & upload them with malicious payloads
* People using LLM-written code then auto-add malware themselves
