Rain is used effectively in human society. It is for agricultural water, drinking water, or power generation.

Besides the rain, society uses various natural and artificial things.
I just came up with the delusion that "If we see human society as a very sophisticated, huge machine, we can observe society positively and constructively?"

I would like to suggest the option of having a sense of being an engineer who repairs or improves society. If I learn in the same way as I learn programming languages, I think I can work harder now.

However, it seems essential to improve the environment for my own study and activities.
