At some point in the future I think spam is going to clog everyones email box. Everyone will be on every spam list so that no one will be able to get real emails from friends or family because their mailbox will always be full. At that point people will stop relying on the computer to remain in contact with people and will once again resort to written letters and the telephone. I guess we will still have online messengers like ICQ but at some point the spammers will figure out how to bug us all the time while we are using them. Actually maybe this whole Internet thing will crumble and fall due to spammers. They will figure out how to use our browsers against us and then people will just stop using the Internet. They will use their computers for computer games and find information in books. We will de-evolve technologically. It could be possible.
