Genetic engineering appears to be infinitely profitable and omnipotent. However, it is worth noting that gene transfer has risks: transferred genes can spread to unintended hosts, they cannot be retracted, and they become permanent. If there is a problem, it could very well be difficult to put the genie back in the bottle.
然而，值得注意的是，基因轉殖有其傳播性、不可逆性和永續性，一旦出現問題，恐怕也難以挽回。
