Are We Too Dependent on Computers? We have become too dependent on computers for answers‚ personal interactions‚ and we spend way too much time on them. If we used the computers for learning and as a tool this issue wouldn’t be as big. The sad truth is that people use this great tool for an easy way to get out of face to face interactions with other people. In 10-20 years it is said that there will be a computer smarter than the whole human race alive today. That is a scary future that we don’t
