'False' life

Recently scientists have created the first synthetic DNA in Microbes. A couple of Biologists edited some DNA within a Microbe, making an artificial living being, and it has lived and been functioning as an ordinary Microbe. For right now, all this can do is edit the way protein is handled within the body. Shortly though this breakthrough in science is a huge discovery regarding in what can happen from here, improving human lives, better and more 'real' Artificial Limbs. As they can be crafted to people with missing limbs to be able to live better, or the entire line of more humanoid robots can be crafted to help with a shrinking workforce. However, there are also large ethical issues that society has to come to a point on. For example, should we even create any more synthetic DNA due to it's 'unnaturally' state, or what of the harm that synthetic life forms can bring? Some famous Sc-Fi films such as Terminator, The Matrix, Alien (the first one), and 2001 A Space Odyssey, explore the issue of robots taking over our lives in some aspect whether that be robots taking over the world or enslaving humanity, most films about robots show how they are evil. These movies might have even inspired the general feel for societies hostility of robots. Some of the issues are legitimate, though. However, all these matters have to be evaluated and seen if they are real threats that should stop this line of science or that the risks are small enough to create something for the betterment of humankind.
