(Continuation from yesterday)

My sister says that this problem is not the "IT literacy" but the risk of "leakage of personal information".

Certainly, if the information of elderly people with dementia leaks, it's like sending victims to cheaters.

It can be said that it is extremely risky.

However, No perfect safe systems are in the world.

To begin with, if a helper or a care manager leaks information, no matter what a robust system it is meaningless.

Apart from that.

When I was working in the US before, my English teacher (American), who I asked for privately,said to me that

"When I lived in Japan before, I realized happiness that I could not understand Japanese"

It is inconvenient that we can not understand languages, however, it is quite happy that we can not understand unnecessary and unpleasant information,

-----

In other words, in the end I am "unhappy" to know how to make an IT system, how to use it.

Essentially, "coming to hate the world that not made like my own" ---- anytime, anywhere, any "idealist" is falling in this hole.

However I could reach the concept that

If "the daily lives of others are the object of hatred against my ideals"

conversely,

then "the daily live of mine becomes the object of hatred against someone's ideals"

It is "Symmetry of hatred" so called.

-----

So I still think that there is not much difference between "Aum Shinrikyo executive" and "me".

If there is a difference, I (A) noticed the "symmetry of hatred", (B) didn't spread the poison gas - that's all.
