The human brain has 100 billion neurons. There are 6 billion people on earth. If everyone had 16.666 (~17) computers connected to the internet and turned them on at the same time, there would be 100 billion nodes in the network. Would 'SkyNet' then become self-aware? {:-D :-D The UK MOD has a computer information satellite system CALLED Skynet !!!}
