I find it hard not to suspect that some countries are using certain policies to subtly eliminate the elderly. Of course, I will also grow old, so the consensus is to rely on oneself—invest and save, just in case. Optimistically, household robots might change a lot. I often think of that example: in the past, people often imagined futuristic skyscrapers but could not imagine elevators. New technologies are always unpredictable. There is a Chinese saying: “Where the cart reaches the mountain, there will be a path,” so perhaps there’s no need to worry too much.
