are we individual computers or as other suggests part of giant computer program?
Nay, I don't think so.
Computers work electro-mechanical, our brains work electro-chemical. Our thoughts and memories work quite different than a computer hard-drive. We actually don't store but recreate a memory every time we think about it by allowing certain synapses to shoot simultaniously and in sequences. Our brain system is a million times more complex than any computer processor, even though we cannot calculate as fast as computer programs.
And that's why I believe we will never create conscious computers or robots.
Good points. Thanks for reading :)
