Pardon me for the spoiler, the answer is negative. No, they shouldn't be.
According to current Assisted Reproductive Act in Taiwan, the uses of reproductive techniques are legally limited. So I think it might be a great start to discuss the legislative intent of the current law.
First, we know Assisted Reproductive Act was mainly drew up to protect infertile people and assisted reproductive children. This is the most important and inviolable core meaning of which. Every article of Assisted Reproductive Act scrupulously prevents people’s rights from assisted reproductions.
Threre are many cases shown. Some parents asked for reproductive techniques to achieve their short-term goals, but ignored possible injuries to babies’ right. Of course these parents’ positions are quite pitied, however what’s good for the kids matter the most and they forgot about this point. It is not be allowed legally and shouldn’t in reality.
Technology is for everyone. Selfish choices which may hurt others should be banned. And also we should consider the possible social structure changes because of the uses of reproductive techniques.
What if we allowed parents to choose their babies’ sex or even traits? Forget those religious and moral questions like “Should we play God?”. It would be a stupid behavior to agitate the gene pool of humans, and it could bring unknown dangers to our entire specie’s existence.
There are billions of intentions of people, countless people want to approach these techniques. However the risk is great and obvious, it’s never wise to grant everyone who asks for. We should be more careful while developing our technologies, especially when they’re life-related. Humanity has its own value, and as humans, we got the great obligation to defend it.
And it’s not just about reproductive techniques. Humans must use any kind of tech with cautions. Or maybe someday we would have to pay the price.
