<human>:  With respect to the ethics of genetic engineering, when should we use it?
<bot>: Genetic engineering is a very controversial topic. Some people think that it is unethical to use it, while others think that it is a great way to cure diseases and improve the quality of life for many people. I think that it is important to use genetic engineering in certain situations, but I also think that it is important to be very careful about how it is used.
