True, but the civilization that creates the simulation is much more advanced, so it will be worst than having babies looking for errors in professional coding.

Okay, maybe not holes but, parts of the code that can be exploited over other characters in the simulation not looking for them.

If the simulation theory is right, then actually there is somewhere to get. The "mother" reality or whatever we want to call the place in which our reality was born.

There is an assumption this is possible. Perhaps we are air-gapped. Although, there is always a chance for us to advance well enough to convince the simulators to release us... Like any AI worth a grain of salt ;)

Would you like our reality to be a simulation?

For me, it doesn't change much and like I have said before, it is similar to my god/no god view. Do my best while looking to do better. Live a life that ends well, live a life that continues well. The actions of my life don't change much. If you look at the entire process of the universe, it is essentially a simulation whether directed or not. Nature doesn't know what is coming so it developed diversification of resources to increase chances of continuance even though it has no awareness of what that would be as it lives completely in the moment, always.
