Homo Deus(Yuval Noah Harari)

 1. Human adaptability and expandability


Before writing was invented, stories depended on the limited capacity of the human brain. Therefore, stories that were too complex for the human mind to remember could not be created.

I personally think that writing is the greatest invention of mankind.

If there were no writing, most of society, including history, culture, architecture, and science, would not exist, and we would have been wild animals just living day by day.

We have grown at an incredible rate by communicating, cooperating, and recording.

Looking at the above quote, in the past when there were no cell phones, everyone memorized their home phone numbers, pager numbers, etc.

Now, smartphones store a huge amount of information.

My personal opinion is that we should not enjoy these convenient devices, but rather leave our limited personal limitations to the devices and create and make new things.

That is why humans should study more, develop, and continue to accept new things. Because something new will come out again, and if you discover or develop it first, you will make a lot of money, and if you adapt first, you will be able to educate others, and if you are eliminated, it will be difficult to survive.


2. The greatest economic value is technology.


Where do you think the big change in the 21st century will come from? Will it be the terrorist group ISIS or Google?

In the past, there was a war special, and neighboring countries achieved growth through great economic benefits due to war.

A representative example is Japan's huge profits from the Korean War.

Korea also benefited from the construction of the Gyeongbu Expressway due to the Vietnam War.

However, now, a well-made smartphone has a greater economic effect than an economic special caused by destruction and killing.

I think that humans grow a lot through collaboration.

For example, I think that a small smartphone is produced with the help of many countries (each part, function, technology, production, etc. requires help from all over the world), and the stock price of the company that produced it rises due to the produced smartphone, and the company gets funds when people around the world buy smartphones, and with the funds gained, it develops new smartphones and grows even bigger.

That is why I think technology is the most important in human life.


3. What will the future ideology be like?


Capitalism divides and processes data, while communism processes everything centrally.

Capitalism has brought abundance to the world.

Its foundation is the economy and capital that continue to expand due to the credit and currency system between people.

In the abundant information age, information overflowed and the need to manage this information arose.

In the near future, that much data (biometric information, preferences, personality, thoughts, etc.) will be managed and customized for each individual.

In other words, the ideology of the country will no longer be important, but the importance of the individual will soon increase. In my opinion, communism will soon be completely eliminated.

Most people in the world, except for communists, have smartphones and can immediately learn about world trends and information from anywhere.

The amount of information that individuals can obtain now is unimaginably different from the past.

Will the young people who were drafted into the war really benefit from the Russian-Ukrainian war, while only Putin will benefit politically?

Will the citizens of China, who lost their freedom by controlling the coronavirus, be happy?

Do the people of North Korea know that the world is changing so rapidly?

I think communism will collapse because it cannot handle this overflowing amount of information.

And I hope that our country will also remain in its current free democratic system, and it would be good to know that now is the happiest time.

God delusion(Dawkins, Richard)

  1. It is the role of science to let us know the facts. Mystics rejoice in riddles and wish for them to remain mysterious. Scientists rejoice in riddles for a different reason: they give them something to do. mobile e-book: 320p In the past, humans practiced totemism, animism, and shamanism, offering sacrifices to improve the weather, performing rain rituals, or, as in the legend of mantou from the Romance of the Three Kingdoms where twenty head-shaped buns were offered to a river god to calm its waters, taking various measures to appease the wrath of gods through sacrifice. However, because science has developed, modern humans can now predict, to some extent, why weather phenomena like the rainy season and typhoons occur and where they will strike. We can even induce rain through artificial rain technology. Thus, when we are ignorant of the facts, things may seem miraculous and be seen as the work of gods, but once we know the facts, we can understand them. It seems that humani...

Parenting from the Inside Out(Daniel J. Siegel, Mary Hartzell)

  1. Let's Reflect on Ourselves "When you pay attention to your own experiences when you get angry at your child's behavior, you begin to realize how much your reactions have interfered with an ideal relationship with your children." (e-book p. 70) There are moments when I get particularly angry at a specific behavior of my child. I ask myself, "Why does this action make me so angry?" and "Why am I reacting so sensitively?" I reflect on whether I, too, received negative feedback for the same behavior in the past. By contemplating my anger and looking back at my past, I come to understand the root cause of my sensitivity to that particular action. I realize that my specific reactions are also responses stemming from past experiences. Therefore, to change my behavior, I must first acknowledge the origin of my reaction and then consider how to change. Through this process, I can restore my bond with my child and achieve deep self-reflection. My ingr...

Mindset: The New Psychology of Success(Carol S. Dweck)

  1. Life Is Yours "It is your chosen perspective that determines whether you can become the person you want to be and realize the value of your life." Mobile e-book: 27p Even when faced with the same situation, everyone reacts differently. I believe that life's outcomes are ultimately determined by our own choices. I think our current state is a result of our past choices. For instance, writing this book review is a consequence of my past decision to read the book. And my improving writing skills (though still lacking) are a combination of past writing experiences before starting the blog, plus the experience of writing more and more since starting the blog. This has led to the current result where I can now quickly write a book review in 1-2 hours (and marking important lines while reading helps reduce time spent on quotes). Similarly, your current state is a product of your accumulated past experiences, efforts, and trials and errors. No one is good from the start. Wha...
