Small change in mean can result in big change in extremes
We have witnessed the recent extreme heat in the US Pacific Northwest. The city of Seattle (one of my favorite cities!) set a new record for the highest temperature ever recorded: 108 degrees. Incidentally the previous record high of 105 degrees was only 11 years ago in 2009. Why do we see extreme weathers more often? I think…

(Arts and AI Series) The Entropy of Creativity: A Revolution or the Decline of Human Creativity?
AI and arts – it is such a vast and fascinating topic that I intend to keep writing about this. Let’s see where I will go with this. This topic fascinates (and worries) me because arts are the souls of human beings. Without art, we lose one of the most important markers as a unique…

To Straighten a Bent Stick, You Must Bend It the Other Way
The above saying is actually from an old Chinese idiom. I have thought about it a lot, and have struggled with that too. Finally, I have concluded that it is true. Here are some of my thinkings that help me arrive at the conclusion. Imagine a bent metal tube—perhaps from a bicycle frame or a…

Why do we crave for speed?
I am writing this at a ski place in New Hampshire. The spring sun is warm, and the air is fresh. I am sitting in the rest area directly overlooking the diamond slope where skilled skiers zip down the steep slope with curves and ease. I can imagine how exuberated they must be feeling. But…

SOLAH: The 5 Functional Pillars of Every Business
I have always been pondering about how to convey the essence of a business. There are many aspects to a business, and it seems in business schools we tend to either say everything is important, or say a particular area is the most important. To me, that is the wrong idea. My sense is that…

The real threat to American prosperity
Given that I just wrote about the dominant status of US on the global economy, it seems strange that I now write about the downfall of the US. Well, while the US is still ahead, I am also convinced that the danger is real. Financial Times recently published a long article by Daron Acemoglu titled…

What is AI good for? (Feb 2025)
We know AI can do a lot of things, but not many things well (yet). Nevertheless, people including me are using more and more AI, so it is useful to think about what it can do and do well in the real world. Recently I read a WSJ article that summarizes reasonably well the status…

Is DeepSeek a hoax?
Today (Jan 27 2025) is a historical day for the AI-related stocks. NVADIA dropped 17% in one day. Broadcom dropped also dropped 17%, Google 4.2%, Microsoft 2.1%. All because of a Chinese AI startup called DeepSeek. We will know more as time goes on, but my initial reaction is skeptism. From what I know about…

Visualize the AI Ecosystem
AI is all the rage these days. But few people have a clear picture of what the AI ecosystem looks like. I have been thinking about it for some time, and feel that a supply chain perspective can do the job. Not long ago, I had the good fortune of listening to one of Barry…

Khanmigo Offers A Glimpse of what AI can do to help future education
I am a fan of Sal Kahn, the person who not only founded Kahn Academy, but also have been working tirelessly to help better education for the past twenty years. The fact that he does not seek a monetary profit is enough for me to respect him. And the fact that he cares for and…

2025: A Year of Uncertainty(?) and Growth(!)
It is 2025. What will it bring? It is fair to say that I have no idea. Looking back, who would have thought that the stock market would be one of the best years? I did not. The S&P 500 soared 24%, making 2023-2024 the best 2 consecutive years since 1990s. I remember one year…

The American Civil War was a War on Supply Chains
I love to look at the Early Modern Period and the Modern Age through a capitalist lense. I see the significance of capitalism in almost every turn of historical events when I read the excellent book “Americana: A 400-year history of American Capitalism” by Bhu Srinivasan. After I read the chapter on the American Civil…

The Transportation sector is much larger than the entertainment industry… but why do people think the other way?
This is a simple post about building the right perspective on sizes of different industries. I was listening to one of favorite supply chain management podcasts “Freightvine“, hosted by Dr. Chris Caplice at MIT, where he mentioned an interesting fact that the trucking industry is about 10 times larger than the music industry, which we…

How the consulting world screwed up the ‘Lean’ Idea
The lean idea was started by Toyota in the war-torn Japan in the 1950s, almost by necessity. It turns to be very effective and helped Toyota grow and even dominate the world auto market towards the end of the 20th century. It also fundamental influenced the industrial world.

Excel trick: Search for multiple keywords from a list
Recently I was given a large spreadsheet with people’s expertise written in long phrases, and I had to identify those people who have AI-related expertise. The issue here is that people can enter a variety of phrases such as “machine learning”, or “large language model”. How do I quickly identify those people? Fortunately we can…

Sometimes change is good just for change’s sake
“If you move a tree, it will likely not survive. But if you move a man, he will most likely thrive.” It is an old Chinese saying. And over the years I came to firmly believe in the profound wisdom of that. Looking back at my life, I have benefited from every major change I…
