If only the "Emperor and Expulsion of the Barbarians" had been accomplished, Japan could have avoided the Pacific War, the bursting of the bubble economy, the Fukushima nuclear accident, and the corona disaster, and maintained a peaceful state with an annual GDP growth rate of 0.01%.
Having come to this conclusion, the Japanese government began to implement a plan to send anti-Android weapons to the end of the Edo period, 170 years ago, for the purpose of defeating foreign enemies ---- In order to achieve Japan's "1,000-year isolation.
I've never heard of this movie idea.

We can watch movies about androids being sent from the future to the present for the purpose of falsifying history, but we cannot accept androids being sent from the present to the past.
Our perspective is always based on the world we live in at the moment.
We are "bothered" by the idea of our world being different from the present.
Even though the present is built on an unhappy past -- we don't have the energy to falsify the past to create a "different world" from the present.
-----
For example, the Pacific War killed more than 3 million people in our country and almost destroyed the Japanese system.
However, I have not seen any novel, simulation, or movie that shows what Japan would have been like today if the Pacific War had been avoided.
Even though the present is built on an unhappy past -- we don't have the energy to falsify the past to create a "different world" from the present.

For the sake of the children of the future, barbarian extermination was discussed, the Pacific War was started, the abnormal increase in the value of real estate was created, research and development of nuclear energy was carried out, and now people are refraining from going out.
But what will the "children of the future" think?
Do we, the "children of the future" from the perspective of the people of the past, think that the decisions of the "adults of the past" were "well done! Do we, the "children of the future" from the perspective of the past, think, "Well done! Or do we think, "They did something we didn't want?
We, the "children of the future," honestly "don't give a damn.
We don't have time to admire or hate the past.
We are so busy living in the present that we don't have time or ideas to think about such things.

That's why I feel very uncomfortable when I see people who abuse the phrase "for the sake of future generations" -- for example, cult leaders, opposition party members who ask questions in the Diet, and old men in neighborhood associations.
