One day our ancestors designed a wheel. Then someone invented electricity. People are always going forward in technology. That brings a lot of possibilities but many problems as well.
The scare that well designed robots will decide their actions by themselves is understandable. People have heard many stories about it.
And usually, they are not so bright. Actually our devises are already following us. They offer us the things that we need. They show us advertisings, that we want to see.
Sometimes it’s really scary when you think that your phone knows you better than anybody else. Robots are taking many jobs from people right now.
