How many robots are there in the world as of now?

There are about 3 million robots right now that are being used in various factories this 2020. It is possible that the number of robots will increase even more in the future. In fact, it is estimated that the number of robots will double in the next few years. There are just more and more industries that are starting to use robots to provide the items that they need to serve their customers.

Some people find this alarming, especially since they feel that there is a big chance that human beings will start to become replaced by robots in the future not only in providing services but also in living in this world. Some humans will probably want to become robots, too, so that they can live forever.
