Knowing all the code, one can generate everything and present the world on a computer?

Q: Knowing all the code, one can generate everything and present the world on a computer? A: Your viewpoint can be more concise: as long as I can write it down (give an expression), I can do it (see it in reality). Your understanding is quite poor, that is, you intend to use extremely complex reverse engineering to construct rich details of real life in a pure code and formal world; But have you ever thought about a problem? Code is purely dead, running there, and as long as you don't feel it, you can't confirm its authenticity. Your feelings are built on complex neurons, which means that the information content of the system that can make your feelings feel real must be at least the same order of magnitude as the information content of your neurons, in order to respond to changes in your neurons at any time. To generate "real everything" in a computer, there are two directions of action. The first is to continuously enhance the chip body of the AI god; The second is to make oneself simple enough (stirring up one's mind to become stupid, or lowering one's expectations for reality).
