Now, regardless of our hope, we are Microsoft's "Windows OS" and "Office" slaves...I mean "users".

In the proverb dictionary, in the explanation of "the army if you win", they have to use an example, "Wining story of Microsoft Corporation", instead of the shogunate at the end of the Tokugawa shogunate and the new government army.

By the way, in this column, I wrote a little about "Nash equilibrium" and "Pareto optimal".

Many of us have been forced to upgrade our version by Microsoft Corporation, with the threatening phrase "We do not support anymore" OS and Office", though even we have finally got used to OS and Office over the years.

We use the present Windows OS to reach the so-called "Nash equilibrium", and the world is warm, cozy.

However, Microsoft breaks this Nash equilibrium, and try to be reaching Pareto optimal, as a means of "upgrading + halting support", however I am afraid that this is a Ultra Super good faith for the company.
