The book “textbook of easiest Web3” has benn recalled. According to Impress which is the publishing house, it is difficult for the book to publish the corrected edition because the description has too much mistake.
Seemingly, the book does not have common translation of technical term.

On the other hand, the definitions of Web3 has not become settled yet.
What must be considered in such status is how to create new value. Of course, technical discussion is important and the common view over technical term is also required. However,

if only such technical discussions are carried out, you do not lead to new value creation.

See GAFA. It is not cutting-edge technology but the service marketspace in the world which GAFA has controlled. They do the judge of various technologies and they are devoting all their energies to creating new value combining them. It is because they know well that new value will charm peoples and will overwhelm the marketspace.

I am always thinking that Japan and U.S. are almost same in ICT or digital technical capabilities. A big inequality is the ability of creating value.

It is time of concentrating on the improvement in the efficiency for value creation now.
