Arendt Hittse is a specialist in artificial intelligence and as such is optimistic on the question of whether we should be afraid of machines . He believes that there is no need to shy away and there are no special reasons for concern. But here's what would be afraid if it decides that it is necessary:
Fear of unforeseen
In many complex machines, such as "Titanic" NASA space shuttles and nuclear power plants (such as Chernobyl) engineers combined a number of components at different levels. Designers can know well enough how each component works, but probably are not aware of how they work all the components together. This means that many systems can not be fully understood in theory may cease to function in unpredictable ways.
Fear of abuse
Soon machines will be able to create will reach the level of human intelligence. With each generation, they managed to cope with the mistakes of the previous getting better. And it increases the likelihood to encounter adverse events simulations that can be eliminated before they enter the real world. But the fear of abuse even with the most sophisticated machinery remains.
Fear of social priorities wrong
Maybe one day all human activities will be carried out by robots . In the near future is possible automation to push us all outside the realm of robotic activities. But it can make people who are owners of the machines, richer, and everyone else - poorer and thus cause social damage.
