In reality, there is no healthy captain at all. The captain can be said to be a conscious vegetable. In reality, people use technology to send the captain's soul (let's describe it for the time being) to the source code world, so that the captain can perform the task (that is, the rescue task, which is actually not a task, feels like serving 0 0). Finally, after N failures, he finally completed the task, and in the process, he also fell in love with that beautiful woman. He knew that once he went back, he would continue to perform the next task and leave the beautiful woman, so he sent a short message to a real person (I forgot, I saw it a long time ago), asking her to stop the machine operation after the task was completed (because he relied on the machine to maintain his soul's life, and if he stopped, he would never have to perform the task again, that is, he would die completely), and his soul would stay in the source code world because of the stop of the machine.
