This is a thought I had in my head, that being said...
You traveled light years just to find a strange silver planet and you see that there are some life over there along with robots. As you visit this strange planet, some aliens/robots found a way to communicate with you and offered you to sacrifice your physical body and brain to live in the matrix world.
The alien said : "Welcome to this planet, here, you will find living beings sacrificing themselves to live in the matrix world, and as they go into the Matrix world, they live in a world similar to Earth-like planets being free from harm. In the Matrix world, they'd see that there is no observable difference between the physics of that universe and the physics of this universe, and they cannot cease to exist as long as this planet is alive. The robots you see here are tools that living beings in the Matrix world use to explore the universe in which you are at now. In the Matrix world, you are to live in peace with other humannoid with the opportunity to do anything you would like to do bounded by the laws of physics, and you can take any kinds of jobs/hobbies you would like to have. Each time you die in the Matrix world, you are automatically revived. You can never feel harmed in this world because you are free from feeling or perceivably harmed to this world. You can communicate with other humannoids and discuss anything you would like with them provided these humannoids are willing to communicate with you, and there is almost everything intelligent species can have to offer. The economy in the matrix world is always prospering well as resources are virtually endless.
So, would you like to sacrifice yourself to live in the Matrix world?"
And, as time pass, this alien provided evidences that the matrix world is indeed legitimate, and there is no evidence against the legitimacy of the matrix world. So, would you take the offer? What would you ask the alien?
