What does the future hold for mankind? how will we use genetics?

The future for mankind is hard to predict because humans can't exactly know what will happen in the future. However, one thing we determine that if we abuse genetics in the future, our world will come to the end. If we want to continue to live in this world, we have to handle genetics nicely. If we want to use genetics, we will make human replicas, which are convenient to people and they can do as original people. We can invite experts to copy your human replica which looks like you, and then you can order this replica to do whatever you want. However, although it is nothing bad to human beings, if you use it indirectly, it might can destroy the world. For example, if some people think in the wrong way, they might use their own replicas to kidnap, steal, or commit. Although they are found with guilt, real people don't matter because people have done what they want. it sounds like tiny thing, but when this event happens again and again in the future, the world will be suffered and people will be hard to live continuously.
