・Twenty years have passed since the IT revolution, and many entrepreneurs have dreamed of becoming mega-ventures, but they were not born in Japan. The reason for this is that entrepreneurs misunderstand the business model and profit structure. Sales begin with the sale of personal information, and the structure relies on low-cost servers made in China for data centers (p23)
・There are no users who buy unguaranteed counterfeit or defective products at real stores, but there are Amazon. That is an important source of revenue for Amazon and China (p36)
・There is emission rights at the origin of climate change countermeasures rights, and I think Tesla's final profit and loss in 2020 was 720 million dollars, the first surplus since listing, but about 1.5 billion dollars is emission rights revenue, and 2021 succeeded in dramatic cost reduction for Model 3, and achieved profitability with only automobiles (p45) In a secret agreement between Tesla and the Chinese Communist Party, “Tesla is a local Chinese parts company There is content that “preferential treatment and technical guidance = technology transfer” (p47)
・Apple's gross profit from products is 30%, and gross profit from services is close to 70%, and both are 37133.2 billion dollars in 2021. In addition to products, profits from iTunes etc. are stable. (p51)
・Most IT businesses are data businesses, and if cloud operators that store data betray them, everything ends, and cloud operators hold the lifeblood of IT operators. Previously, Amazon had a video distribution operator as a customer, but that server was shut down before winter vacation, and the Amazon Prime Video service was started instead (p67)
・The reason why global SNS is not coming out of Japan is that this is not a software business, it is a server business, and since it is an industry requiring huge investment (p71), the accumulated data of people receiving free services (free) is a huge amount of data center costs, causing an increase in data center costs, and Taiwanese and Chinese products are sold, not those made in the US or Japan, which are expensive to lower that cost, and the result is that the IT industry's dependence on China is strengthened becomes (p107)
・If you try to have GAFA or the like buy a server, they will undergo a design check, examine the purchase price of all parts, and request a price reduction. Furthermore, under the condition of purchasing a large batch of servers per year, all parts are calculated at the lowest cost, and the manufacturer's profit is insignificant, which is behind the fact that hardware manufacturers have declined and many computer manufacturers have been acquired by Chinese companies (p115) There is a risk that the same thing will happen in the automobile industry, and there is a risk that the same thing will happen in the automobile industry, and “dental platform” “automobile OS” “automobile OS” ” Companies reign supreme (p115)
・EV cars are a bright lie about being eco-friendly (CO2 is emitted as long as oil or gas is burned at power plants), and when the market share of EV cars increases, there are many advantages in China, EV cars are easier to copy than internal combustion locomotives, Chinese nuclear power plants can be sold, and vehicles can be monitored by connecting EV cars with 5G (p122)
・There was an SNS called Mixi in Japan, but it didn't spread, the number of users did not increase because it created a special feeling due to restrictions such as an invitation system until 2008, and there was no multilingual support called global support, and in the meantime, Facebook became too famous and the shadow faded (p131)
・Google was addicted to the chicken race where the number of users acquired is a game in the internet world, where server costs increase as the number of free users increases, and it was Google that was able to make an upfront investment to suppress it, and Yahoo was impatient with user acquisition and became expensive (p141)
・We assume that we access the internet and freely obtain information through free channels, but in reality, the global market share of Google's search engine, which is confined to GAFA servers, is 92%, so we can only see information that Google determines “OK to look at” for us (p156)
・The purpose of Web 3.0, which American conservatives say Kaia WTI is to liberalize information from GAFA, and the purpose of the Chinese metaverse is to consolidate the entrances to information controlled by GAFA, so that China has all information in its hands (p162)
・In the metaverse, another parallel world of the real world occurs in a virtual space, and all users, including themselves, wear avatars and immerse themselves in the virtual space. The existing internet is a simple two-way form of communication, but it is changing to “interactable” communication. The point is that it is possible to develop an “interactable” virtual world where users can feel each other's presence through avatars. Until now, I've only read comments, but I can even know viewers' facial expressions and gestures. You can enjoy broadcasts with other avatars (p167) Furthermore, you can do digital currency used for payments within virtual spaces and “business” to acquire it (p167)
・The investment world does not invest in the same thing, what people call the metaverse 4 or 5 years ago was virtual reality, without investing in the same keywords. Furthermore, the five-year rain was named “3D.” The source code for artificial intelligence is a combination of statistical modules. When the name of what was called quantitative analysis is changed to artificial intelligence, it is somewhat stylish, cool, and has a sense of the future, so investments are attracted (p206)
・The biggest challenge in the metaverse is three-dimensional image display devices and hologram displays. The current head-mounted display is a device that displays two-dimensional images for the right eye and left eye using the human brain to synthesize three-dimensional images from binocular parallax, and in fact, they are not three-dimensional. Also, the weight is so heavy that it is difficult to wear for a long time. The ideal is a display where three-dimensional images can be seen with the naked eye, or a lightweight visor-type display using a film display; if a virtual space were to be realized as a three-dimensional space similar to reality, no one would return to the current two-dimensional dimension. The number of people reading has decreased due to the development of television and radio, and it is the same as the number of people watching TV decreased due to the rise of internet distributed videos (p233)
