By comparing the Moon to humans, the health of digital life is equal to the functional integrity of humans.
Human disease leads to a decline in physical functioning, further leading to death, and humans therefore have “life expectancy”.
Assuming that Yachiyo would be “dead” because of insufficient memory space, i.e. unable to learn new knowledge or to use the original knowledge movement, death could be determined on the human side. However, the authorities have made it clear that the Moon is immortal, so that there is no problem with the lack of memory space in Yachiyo.
Thinking about it, if humans have a complete memory of 100 years of life, akin to severe amnesia, they are clearly retarded. But Yachiyo, who is a regular moon man, even with a prominent identity, may enjoy the best possible resources, while normal human beings have the same mechanisms to forget. It's not like she can do it. And the only new memory that existed only eight thousand years ago was only a few months ago, and even among humankind.
And then proactively erase memories.
If that were to be done, no one would know that the leaf had been cleared and that the only person who could tell a story was missing from nature, and perhaps it would be better to ignore the man who created the BeDD.
If that were not the case, we would have accepted the future created by both of us.
Suppose Yachiyo tells his own story...
Impossible. Yachiyo, who waits for eight thousand years for a leaf, rather than cheering the audience, would not be doing a meaningless campaign to raise awareness if the leaf had disappeared or could no longer recover its foreground. The colour leaves only remember Yachiyo, the anchor, and we have no way of knowing them.
