Ever thought about who was the best visionary in the world?The best visionary in the world, contemporarily speaking was Arthur C. Clarke, who died on 20th March' 2008. Decades ago, he had stated about how satellite television would invade everyone’s homes, how one will be able to get in touch with each other through a computer and how telephones would change the world around you. In his words, he never predicted the future, he just extrapolated. He had built the world’s first privately owned satellite dish antenna. He had also stated that Artificial Intelligence will attain human levels by 2020.
