* Actually, there were a lot of "credit cards" when Diners Club started the business. One of the oldest such cards is one issued by Shell (oil company) circa 1920, predating more than a decade.
* The real innovation of Diners Club's card was that it was general purpose. It could be used for multiple merchandises, while other cards were very purpose-specific (e.g. Mobil card for purchasing gas from the store, Western Union card for its telegraph service).
A good resource to read about the origin of credit cards is "The credit card industry: A History" By Lewis Mandell.
> My theory is that those early adopters signed up because the card gave the illusion of status or eliteness
The primary motivation to own diners cards was post-pay. To put it simply: you can eat a dish without paying for it now. That was appealing for people who just started to enjoy consuming stuffs. Yes, you still need to pay the full amount every month, but minimum monthly payment (a.k.a. revolving credit) was an innovation yet to be conceived...
It was a gong moment for me when I came across a short passage discussing its foundedness.
* Freedman, Pisani and Purves Statistics, 4th edition (p153)
The major thing that's missing here is that his writings were actually very influential among ancient philosophers, especially ones of the Stoic school.
For example, Zeno of Citium, who had found the Stoic school, decided to become a philosopher after reading Xenophon's Memorabilia. Epictetus, a prominent philosopher of Roman era, references Xenophon's writing as much as Plato.
I wonder since when philosophy became all about Plato.
Source? Taleb AFAIK does not publish his track record in a verifiable manner, so we're left to wondering if his bragging about himself really matches his record.
Yes, the try-and-error process and chance are important, but the convexity of the output function is exactly what makes them so rewarding.
The point the author is trying to make is that the structure of the payoff function matters a lot. Specifically, you need it to be convex for a try-and-error (or random walk) process to become very rewarding.
For example, think about fuzzing C programs, which has been proven to be very productive in terms of software security. But why is it so productive? This is essentially because a bug in a C program can have a quite significant implication (e.g. remote code execution), thus its payoff function is extremely convex. If there was no such property, fuzzing just wouldn't be so much rewarding (This explains why fuzz tests are less used for programs written in memory-safe languages).
The author believes this idea of "convexity" can explain a broad range of phenomena in the human world. I'm not so sure about its applicability, though.

1. Most of Japanese people have exactly zero interest about whaling.
2. Nor they do not understand why western people get so upset about it. ("What's so different with, say, tuna fishing?")
3. Anti-whaling protesters (e.g. Sea Shepherd) are really worsening the situation. Their "activism" (like stealing whale meats) is perceived as, at best, stupid.
This is really a communication problem, guys. Whaling could have been ended many years ago, if no one made such a big deal out of it.
You'll probably like the digest summary of "Skin in the Game" by Guardian.

So, my guess is that something is wrong with the data scraping?

Note: Some googling reveals that the company ("PREMIER DRAGON DEVELOPMENT LIMITED") is a manufacturer / exporter of women's underwear, with 1-5 employees.
I also really enjoyed this book. It was a bitter story of an idealistic Open Source project failing miserably.
