I agree with the above, but I think that we are getting caught up in the details of how difficult it is to simulate a very complicated world.
We don’t know how much computational complexity is needed for self-awareness to arise. I don’t think we even know for sure if a cat or an ant is self-aware, so how can we know how much computing power is needed to make a simulated object self-aware?
It is possible, though very improbable, that a self-aware entity can arise in a very simple world (compared to ours).
Whether or not the world is programmed on the microscopic level (which people have showed will take an extreme amount of computing power) or on a macroscopic level, this entity will begin to have thoughts.
And if more than one attain self-awareness, they will begin to have discussions. They need not start probing at the sub-atomic level before they start to discuss theories about the world.
I’m sure Plato and his contemporaries were not nuclear physisists. They just sat there and theorized about the world. So, in some sense, in Plato’s time, it is almost as if it would make no difference if our world did not in fact consist of atoms.
Of course, in later years, when people started experiments that tested the atomic structure of matter, our world could not continue to behave as if it were defined on a macroscopic level. But for Plato, it wouldn’t make much difference to the content of his philosophical inquiries.
So, my question is what sort of philosophical inquiries can a self-aware entity have?
How much can a self-aware entity (of a similar intelligence to ours) in any environment deduce about things like the nature of existence, justice, ethics, etc, i.e. things that the ancient Greek philosophers dealt with?
If we think of a brain in a vat, even with no external sensory data, can’t this brain have thoughts? Can it start reasoning about existence, etc? Let’s not get hung up on the details of how detailed the simulated world is.
Of course, once you go from philosophy to science and our little sentient Sims start to do research, then I guess the exact nature of the simulation will affect what they can find out.
But, what about philosophically? What truths can any sentient being arive at irrespective of its environment?
