“By the year 2150, over 50% of schools in the USA or Western Europe will require classes in defending against robot attacks.”

With the current rate of technological advancement, artificial intelligence is a very real possibility in the near future. I predict robots with AI will inevitably be uncontrollable and over power their human masters. Schooling and education is what the children of the future need to fend off these super human robots. Therefore, many schools will offer if not require training in robot fighting. The first wave of these schools to offer the class will be around 2120.
