Hello, everybody. I have been actually afraid of posting this thread, because I usually lack in time (you know I have to work to survive), and as far as I know philosophical threads tend to be really long and complex. I consider myself as a layman when it comes to philosophy, so I hope I won't make too much arguing, just because I posted this controversial thread. I truly don't know how many times this subject has been discusses, but I would need your help to understand it more thoroughly, since when it comes to this thread, it makes me confused. I've seen a couple of New Scientist texts where it says that entire universe is a gigantic classic/quantum computer simulation...? I somehow doubt that universe really is simulation, since how would simulation explain the beginning and evolution of the universe that lasted 14 billion years, and our Earth's creation and evolution of all species in the last 4.6 billion years-I honestly doubt the simulation would last that long. When you simulate something it is instantly created after you put it in the hard drive, it doesn't take 14 billion years. And what about human brain you can't really simulate something that adapts to the environment by itself-there is no simulation in it, since it is all brain's function, they don't say that human brain is plastic-which means adaptable and learns all its life. I would also say that none has actually a free will, because of the brain, however, brain itself has "a free will", because none and nothing actually tells the brain how to adapt, brain does it on its own. That would all mean that universe, if creates something like human brain during evolution, cannot obey to whatever simulation does, because it is not simulation that gave the brain ability to adapt and survive in the environment, brain did it on its own-without being simulated. Because if human brain was a part of simulation universe (simulated human brain), than it would obey to simulation laws and rules in the hardware, and we would be all dead. Basically, you would have a simulated universe with zombies, because you can't simulate life, all processes, reactions, changes and etc..., you would have to have knowledge of alll things in the universe, including the universe itself. However. brain definitely is not some algorithm. What do you think? Thanks to all.
