A new book claims to have the tea on why OpenAI's board of directors fired Sam Altman as CEO during its stunning (and failed) 2023 coup.

If the income share of the
top 20 percent (the rich) increases, then GDP growth actually declines over the medium term,
suggesting that the benefits do not trickle down. In contrast, an increase in the income share of the
bottom 20 percent (the poor) is associated with higher GDP growth

On Monday, the company, which describes itself as the “world’s only de-extinction company,” announced the rebirth of the once-extinct dire wolf. The Texas-based bioengineering company used DNA extracted from two fossils as well as 20 edits of the genetic code of a grey wolf — similar to a technique used in the movie Jurassic Park, where dinosaurs are brought back to life by using frog DNA to fill in genetic gaps — to bring the species out of extinction.

US President Donald Trump has slapped comprehensive tariffs on 185 countries worldwide, but not on Russia and Belarus. Why is that?

The imposition of tariffs on the Heard and McDonald islands was meant to close "ridiculous loopholes" and would prevent other countries from shipping through the islands to reach the US, Howard Lutnick told the BBC's US partner CBS.

unless you're Russia, Belarus, or Hungary

"The additional ad valorem duty on all imports from all trading partners shall start at 10 percent"

Corinth and Veuger write that if the tariffs had been calculated correctly, with the same ultimate goals in mind but using the right kind of elasticity figure, the levy on a country like Vietnam would have been 12.2% and not 46%.

They don’t hurt jobs or growth, aren’t trade or economic scoreboards, and can’t be fixed by tariffs.

The complete podcast (and transcript!) of TSMC’s history and business strategy.

What strikes me most about reading Chang’s story is that, despite his immense talent, how often he ends up failing (or at least ends up in situations where he can’t succeed). Much has been made about how foolish Texas Instruments was to pass over Chang, and how if they hadn’t maybe TSMC could have been founded in America, but the reality is more complex and more interesting. Chang not only gets passed over for leadership at Texas Instruments (due to his perceived failures in the consumer products group and his ongoing tensions with executive leadership), but he fails at his next two jobs as well. He’s asked to leave by the CEO of General Instruments, and he’s effectively forced to resign as the head of ITRI after mostly failing to reform it and angering everyone in the process. After he leaves ITRI (his third resignation in five years) Chang wonders if, per the Peter principle, he’s risen to the level of his incompetence.

And it seems like his one big accomplishment at ITRI, founding TSMC, wasn’t exactly a sure thing. Almost no existing semiconductor companies thought Chang’s plan was worth funding; the one that does, Philips, is more interested in currying favor with the Taiwanese government than it is with the merits of the business. It’s very easy to imagine TSMC not getting off the ground at all if things go slightly differently.

Chang’s immense success with TSMC looks obvious only in hindsight; nobody at the time, including the Taiwanese government, other semiconductor manufacturers, and Chang himself, saw it that way.

The paper “The black hole interior from non-isometric codes and complexity” by Akers, Engelhardt, Harlow, Penington, and Vardhan (JHEP06(2024)155) does make a credible claim to resolve all three components of the black hole information problem in a unified framework.

The Three Paradoxes Resolved:

1. Finite black hole entropy (as required by Bekenstein-Hawking entropy),

2. Unitarity of black hole evaporation (consistent with the Page curve),

3. Semiclassical effective field theory validity inside the horizon (to explain the interior modes and entanglement).

Hawking's original argument was that you can't have all three simultaneously. This paper proposes a non-isometric holographic map (i.e. not preserving inner products globally) that still behaves as if it were isometric for all sub-exponential complexity observables. In effect:

Null states (states mapped to zero) exist but are exponentially complex and thus undetectable by any reasonable observer.

This allows the interior to emerge via quantum error correction (though not isometrically) and maintains consistency with both the Page curve and unitary dynamics.

This paper is a strong candidate for what Harlow refers to when he mentions resolving all three paradoxes of the black hole information problem.
