Why do people think that they will have access to the Internet and there will be massive amounts of excess computing power to waste if the world economy collapses? Computers and the Internet are luxuries that exist because basic physical needs are met. As soon as the Internet fails for any length of time for a given person, that person will refuse to rely on the Internet for anything until the world economy is back together, if it gets back together. In the event of collapse, it will be necessary to rely on local, physical things rather than the complex, interconnected global system we have now.
