There is no experience, only execution.
The last few days, I read a review of the movie Alien: Covenant. The author defends the actions of David, the robot in the film, who, in the author's view, is doing nothing more than carrying out the basic program given to him by his creator, Weyland, their agreement at the beginning of the film: to find the creator of humanity.
So even though David, as the most human-like robot ever created, exhibits many human characteristics, such as imitating humans, learning human culture, experimenting with love, and even trying to understand homosexuality, he has never been able to break through the underlying code rooted in his "brain" to do what he wants. This is the root cause of his unusual ruthlessness and cruelty. For robots, all obstacles that stand in the way of achieving their goals must be removed unconditionally.
As a simulator with a perceptual program (I can understand that you are referring to humans here), there is also the underlying code that is rooted in the simulator or in our human genes. From the point of view of elementary particles, human beings, like all life, the goal of the underlying code is to maintain the stability of the particle complex, and if the particle complex breaks down, the entire program has failed.
So, if we think of life as a kind of procedural simulator, the so-called experiences and experiences are just to make us more sensitive to beat the natural selection in order to be able to live as long as possible.
But are experiences and the pleasure they give us real? I think it's real, but it's real only within ourselves.
So, whoever wrote us as programs must have asked us only to execute them perfectly, not to remember or even relive them.
So who is responsible for the experience? The answer is only us, because only we can care about and evaluate the value of these experiences.
