Is Machine replacing man?

While in 19^th century computer came into existence , the purpose of computers was yet unknown. It was a machine used for computations, later it was a machine that not only did complex calculations but also stored data, and ever since then the field of computer science is booming. And now when we talk about the flourish of technology in 21^st century we talking about Automation, Descriptive and predictive systems,  also image processing and many other fields of machine learning and on a whole Artificial intelligence. There was a time when a bunch of people sat in a room and did data entry and that was quite a rigorous task, but now it is done by machines , and yes it saves a lot of time and manual efforts, and somehow is also unerring. I recently did a project on automating a website, and it saved up to four hours of manual data entry per day. Well, isn’t that amazing? That night I sat and I was thinking soon I see a lot of computers around me  than people. Well, I believe that if we keep on going at this pace soon there will be machines building machines. There will be machine who will know things better and have knowledge far more than a man can possess. But what you think people like us will do then?
