In the future, "lotus petal" technology will be prevalent: the rich upload pain in exchange for a perfect life; the poor download pain to make a living. I am a top "pain bearer" and can withstand the most severe physical pain, until I accepted a sky-high price order - download three minutes of near-death pain. The severe pain was actually wrapped in a forgotten memory of death and heartbreak. Only then did I realize that what we trade is never pain, but human nature and memory that are clearly priced.
