21 Lessons for the 21st Century

I’m not up to reviewing Yuval Noah Harari’s latest book (21 Lessons for the 21st Century) but I liked this one by The Guardian. I really liked his two previous books, Sapiens and Homo Deus, and you can read some of my favorite excerpts in previous posts. I’m doing the same below but first I’ll say this book made me questions some of my long held beliefs. Nationalism, Religion and Immigration, just to name a few. This is a good example of what I mean when I suggest you ditch Facebook and TV news and read a book.


“The Industrial Revolution has bequeathed us the production-line theory of education. In the middle of town there is a large concrete building divided into many identical rooms, each room equipped with rows of desks and chairs. At the sound of a bell, you go to one of these rooms together with thirty other kids who were all born the same year as you. Every hour a different grown-up walks in and starts talking. The grown-ups are all paid to do so by the government. One of them tells you about the shape of the earth, another tells you about the human past, and a third tells you about the human body.”

“If somebody describes the world of the mid-twenty-first century to you and it sounds like science fiction, it is probably false. But then again, if somebody describes the world of the mid-twenty-first century to you and it doesn’t sound like science fiction, it is certainly false.”

“When a thousand people believe some made-up story for one month, that’s fake news. When a billion people believe it for a thousand years, that’s a religion.” 

“As a species, humans prefer power to truth.”

Trust in the dollar and in the wisdom of the Federal Reserve is so firm that it is shared even by Islamic fundamentalists, Mexican drug lords, and North Korean tyrants.”

“A priest is not somebody who knows how to perform the rain dance and end the drought. A priest is somebody who knows how to justify why the rain dance failed.”

“In 2016, despite wars in Syria, Ukraine, and several other hot spots, fewer people died from human violence than from obesity, car accidents, or suicide.”

““Once AI makes better decisions than we do about careers and perhaps even relationships, our concept of humanity and of life will have to change.“”

““Democracy in its present form cannot survive the merger of biotech and infotech. Either democracy will successfully reinvent itself in a radically new form or humans will come to live in “digital dictatorships.””

“In the twenty-first century data will eclipse both land and machinery as the most important asset, and politics will be a struggle to control the flow of data. If data becomes concentrated in too few hands, humankind will split into different species.”

“So in the twenty-first century religions don’t bring rain, they don’t cure illnesses, they don’t build bombs—but they do get to determine who are “us” and who are “them,” whom we should cure and whom we should bomb.”

“We think we know a lot, even though individually we know very little, because we treat knowledge in the minds of others as if it were our own.”

“If you cannot afford to waste time, you will never find the truth.”


Sam Harris “conversation” with Yuval Noah Harari

DSL vs. AT&T Wireless

We have a DSL line from our local telco for internet access. We pay $45 a month for 10 megabits download speed (never get more than 8) and less than 1 megabit upload speed. Not great but all that’s available where we live.

Been having problems for the last couple of weeks with technicians coming up to check lines, etc. Keep thinking they have it fixed but the problem persists so we’ve been using the hotspot feature on our iPhones. Yesterday I stopped by the local AT&T store to talk about our data plan to avoid getting surprised by a huge bill.

We’re currently paying $130 a months for 15gb that Barb and I share. Historically, we use very little of this but if we start making heavy use of the hotspot feature that could change. Without getting any further into the weeds here, I upgraded to an “unlimited” data plan for $150 a month. But the plan lets us stop paying for HBO and we get some other discounts so the faster service winds up costing me less than I was paying.

I’d never checked to see what kind of speeds I get from our AT&T wireless so I figured this was a good time to take a look. We’re getting 18 mbs down and 5.6 mbs up. More than twice as fast as the DSL line!

We don’t stream a lot of movies but do have Netflix, Amazon Prime and Apple TV. I’ll keep the DSL service for a few months while we monitor our wireless data use, but I’m thinking I can adios the DSL.

This is might be more noteworthy to me because I remember the dial-up modem days. 2400, 14,400, 56K. Dark days? An exciting time? Could never have imagined I’d be able to connect to the internet with a mobile phone. Could never have imagined a mobile phone.

Smart glasses

I’d pay $1,000 for really smart eyeglasses. People who have LASIK surgery tend to rave about how it changed their lives for the better. Fortunately I’ve been blessed with good vision because I just don’t think I could let someone cut on my eyes unless there was no option. These surgical (?) techniques will — I assume — get better and better. That’s a good but I’m counting on eye glasses getting smarter.

A lens that could monitor what’s happening with my eyes as well as my surroundings (light, motion, etc), and adjust on the fly. Reading a book, looking at a laptop screen or a mobile device; watching TV or a movie.

One more thing. A coating on the lens that is impervious to greasy fingerprints.

Car dealerships are doomed

Long-time auto exec Bob Lutz thinks car dealerships are doomed. They have 20 to 25 years left. Autonomous vehicles will completely disrupt the industry.

”Are they going to be fun? Absolutely not,” he said. “There will be no joy in sitting in an autonomous vehicle …. But it’s going to be enormously efficient.”

He suggested that parents will be willing to place their children in autonomous cars to take them to day care, soccer practice or school. He said they would be able to give their children limited access to a vehicle subscription service that would let them call cars to take them to preapproved locations, and that access could be expanded as they get older.

”When you send them off to college, you won’t send them with a car, you’ll send them with a subscription to a driverless vehicle service that they can use at their leisure,” he said.

I think it’s been a long time since cars were cool (not that I was ever a car guy). They’re all look like gray blobs of molded plastic. Lutz says the car of the future will just be a “module.”

He likened the modules to subway cars: Passengers don’t know who makes them, only that they get the riders to their destinations.

If I can drive my (mythical) Land Rover for five or ten years — and it’s as much fun as I hope it is — I’ll count myself lucky.

Beyond the Bitcoin Bubble

Excerpts from a really good article by Steven Johnson in the New York Times.

The real promise of these new technologies, many of their evangelists believe, lies not in displacing our currencies but in replacing much of what we now think of as the internet, while at the same time returning the online world to a more decentralized and egalitarian system. If you believe the evangelists, the blockchain is the future. But it is also a way of getting back to the internet’s roots.

After a period of experimentation in which we dabbled in social-media start-ups like Myspace and Friendster, the market settled on what is essentially a proprietary standard for establishing who you are and whom you know. That standard is Facebook.

What Nakamoto ushered into the world was a way of agreeing on the contents of a database without anyone being “in charge” of the database, and a way of compensating people for helping make that database more valuable, without those people being on an official payroll or owning shares in a corporate entity.

If you think the internet is not working in its current incarnation, you can’t change the system through think-pieces and F.C.C. regulations alone. You need new code.

Blockchain metaphors

As Blockchain gains more acceptance (not talking about cryptocurrencies now but the underlying tech) I’m seeing more and more metaphors that try to help people grasp the concept. This article compares Blockchain to sharing Google Docs, as opposed to bouncing a MS Word doc back and forth. The DNA metaphor didn’t really work for me. My favorite was the transparent safes (from online forum Bitcoin Talk).

“Imagine there are a bunch of safes lined up in a giant room somewhere. Each safe has a number on it identifying it, and each safe has a slot that allows people to drop money into it. The safes are all made of bulletproof glass, so anybody can see how much is in any given safe, and anybody can put money in any safe. When you open a bitcoin account, you are given an empty safe and the key to that safe. You take note of which number is on your safe, and when somebody wants to send you money, you tell them which safe is yours, and they can go drop money in the slot.”

This reminds me of the early days of “the cloud” and how people struggled to comprehend where their files were if they weren’t on their computer.
