🌈📊 Rainbow Chart
As the ₿itcoin Bulls run at levels not seen since 2017, the infamous BTC Maxi charts are percolating back into the popular consciousness.
This is a so-called Rainbow Price Chart tracking the BTC price over time on a log scale - with pretty bold predictions/implications ala the 📝S2F model.

💰📜 History of Money
Jacob Goldstein, one of the hosts of NPR’s Planet Money takes us on a whirlwind tour of some of the key moments of money history in the last 1,000 years.
🐜💴 The IPO that wasn’t
Jack Ma’s Ant Group was about to close the largest IPO in history, aiming to raise $35bn(!) in one shot, at a valuation ten times that. $3Trn in orders poured in. Dozens of investment banks and law firms were whetting their appetites at the tens of millions in imminent fees. Then Chinese bureaucrats pulled the plug, shocking the investment world.

📚🎧 Wiki Tales
Jimmy Wales used to joke that choosing to build Wikipedia on a non-profit, non-advertising model was either the best or worst decision he ever made — but he doesn’t joke about that anymore.
“If you think about advertising-driven social media…it’s driven them in many cases to prioritize agitation and argumentation in a negative sense over education and learning and thoughtfulness.”
Jimmy chatted to Tyler Cowen about what happens when content moderation goes wrong; why certain articles are inherently biased; whether he believes in Conquest’s Law; the right to be forgotten; why Ayn Rand is under- and over-rated; the continual struggle to balance good rules & procedures against impenetrable bureaucracy; his attempt to build a non-toxic social media platform, and more.
🎨 DeepSea Cafe
DeepSea Cafe, Digital, 2020
“For the first time in history, in large part because of Bill Gates’ challenge, the vaccine has been produced at the same time as it was being developed.”
Larry Brilliant talks about “the best of times and the worst of times,” as good news on vaccines and testing coincides with a terrifying rise in cases in 📝this Wired article.
“This first interim analysis was based on 95 cases, of which 90 cases of COVID-19 were observed in the placebo group versus 5 cases observed in the mRNA-1273 group, resulting in a point estimate of vaccine efficacy of 94.5% (p <0.0001).” https://t.co/cStIjeLOpc— Adam Strandberg (@strandbergbio) November 16, 2020
As you can imagine, orders are flying off the vaccine shelves.
Meanwhile, in the myriad of covid-19 responses different nations and regions are mounting, Sweden seemed to be the control in the global case study.
By all accounts the soft-touch approach is now being iteratively abandoned as the health and economic costs coax more muscular pushback.

This stands in sharp contrast to regions which took an aggressive response such as Taiwan which has recorded extraordinary figures - despite proximity to China.
- The worst period of the outbreak was at the end of March. On a single day (May 31) three people died.
- The other three victims died on March 21, April 12 and May 12.
- The population of Taiwan is 24 million.
- There might have been 7 deaths; sources disagree between 6 and 7 (https://cdc.gov.tw/en/Disease/SubIndex/).
- The IMF expects that they won’t be in a recession in 2020 (https://focustaiwan.tw/business/202010130026)
Ridiculously popular podcaster Joe Rogan hosted sociologist and physician Nicholas Christakis recently. Here’s a review of the latter’s book - Apollo’s Arrow:
“To capture the COVID-19 pandemic requires unusually broad and deep scholarship, and an ability to integrate the too-often siloed domains of science, medicine, epidemiology, sociology, psychology, politics, and history, among other fields. In Apollo’s Arrow, Nicholas Christakis accomplishes this challenging task as few others could, with unusual clarity and an endless array of surprising insights; this book will no doubt become essential reading for a very wide audience. A tour-de-force.” ― Jeffrey Flier, MD, Former Dean of Harvard Medical School

🍜 Cultural (Food) Appropriation
“Almost all of the truly good things to eat in this world are a product of cultural appropriation in some way.” Take two iconic Japanese foods, ramen noodles and gyoza dumplings – “ramen is just a version of a Chinese soup with cold noodles, which the Chinese call La-Mein,” and gyoza are a “Japanese knockoff of what the Chinese call Jiaozi.”
Laziness, 1896, Félix Vallotton
“Sometimes it pays to stay in bed on Monday, rather than spending the rest of the week debugging Monday’s code.” ― Christopher Thompson

What really moves is the earth ans all of us on it.
This ball of rock with a patina of biosphere is always moving taking us with it.
