e-business - You may not know it, but life could be a simulation. 30 July 2002 Birmingham Post 21 Do not press delete: It is possible to live in a Matrix world, say academics To many, it may seem as far fetched as science fiction can get. But hit-film The Matrix might in fact be uncomfortably close to the truth. Just like Keanu Reeves in the cult movie, we could all be living inside a computer simulation. If so, says one expert, you had better be careful not to get yourself deleted. The idea sounds insane. But Nick Bostrom, a philosopher at Yale University in the United States, has done the calculations. His conclusion is that our lives could well be programs developed by a post-human society living in what we think of as the future. And he is not the only one to take the theory seriously. Robin Hanson, from George Mason University in Fairfax, Virginia, USA, goes further and says the way we come across to our 'creator' might determine whether we live or die. In a paper submitted to the Journal Mind, Nick Bostrom outlines how he reached his chilling conclusion. He argues that if it becomes technologically possible to mimic consciousness, the future can only lead one of three ways. First, an extinction event such as an astroid strike might wipe us out before it is achieved, in which case there is no need to worry. Real life is real life. Secondly, future humans will not be interested in running simulations, or there may be laws against it. But the most likely outcome, argues Bostrom, is that humans will one day simulate consciousness and then go on to simulate universes for it to live in. If that is true, the chances are it has already happened and we are living in one. It has been suggested that simulating a mind with a computer program would take about ten to the power of 14 operations per second. While that may seem a tall order, such technology could be available by the end of the century, Mr Bostrom says. Of course, we may be part of the pre-simulation real world or 'original history', he adds. But given how many simulations there will be, the odds are stacked against it. Evidence that we live in a program may be seen in the strange world of quantum particles, a report in New Scientist magazine suggests. A simulated universe, while having to be convincing on the large scale, would not need to fill in every microscopic detail. It might be possible to get away with odd irregularities at the level of atoms and electrons. A conscious 'program' looking at these bizarre features would be tempted to accept them as 'just the way things are'. That is exactly how most scientists view what goes on at quantum scales. According to Mr Bostrom, we should simply accept the situation and live life normally. But Robin Hanson does not agree. He says that if your life is a computer simulation, you should do everything possible to avoid being deleted. The first step is to work out the purpose of the simulation. If it is for entertainment, then you should be funny, outrageous, sexy, violent, strange, pathetic and heroic. If the simulation is for the creator to participate in, then it makes sense to 'suck up to celebrities'.
