the late物理学家兼作家史蒂芬·霍金教授关于edit DNA 产生 “新的超级人类族群race”这一论调caused controversy。
霍金老先生在一系列a collection of 的著述和论文中做出了这些prediction。
他认为：人们会发现改进智力和诸如攻击性aggression这类本能的方法。”他写道。
他认为立法可能无效，因为有些人不能拒绝这样的诱惑 resist the temptation to 改善记忆力，抗病力和寿命length of life（lifespan)
遗传学方面的breakthroughs, make it attractive for人们试着去改进自己。“未改进的人类”则会因此遭受后果implications
他认为一旦这样的超级人类诞生，未改进的人类竞争起来毫无胜算won't be able to compete。
他写道。“他们可能会die out( to become extinct)
但是，questions have been raised about 父母是否会冒险使用这些技术，因为他们担心这样的改良可能会有副作用side-effects。
天文学家里斯男爵是霍金在剑桥大学的朋友peer，男爵提到note加利福尼亚州的一个精子库只提供“杰出elite”精子，包括诺贝尔奖得主的精子，但因为无人问津lack of demand而关门大吉了。
Essays reveal Stephen Hawking predicted race of 'superhumans'
论文透露史蒂芬·霍金关于“超级人类”族群的预测
The late physicist and author Prof Stephen Hawking has caused controversy by suggesting a new race of superhumans could develop from wealthy people choosing to edit their and their children's DNA.
Hawking, the author of A Brief History of Time, who died in March, made the predictions in a collection of articles and essays.
"I am sure that during this century, people will discover how to modify both intelligence and instincts such as aggression," he wrote.
"Laws will probably be passed against genetic engineering with humans. But some people won't be able to resist the temptation to improve human characteristics, such as memory, resistance to disease and length of life."
Hawking raised the prospect that breakthroughs in genetics will make it attractive for people to try to improve themselves, with implications for "unimproved humans".
"Once such superhumans appear, there will be significant political problems with unimproved humans, who won't be able to compete, " he wrote. "Presumably, they will die out, or become unimportant. Instead, there will be a race of self-designing beings who are improving at an ever-increasing rate."
However, questions have been raised about whether parents would risk using such techniques for fear that the enhancements would have side-effects.
The astronomer Lord Rees, who was a friend of Hawking at Cambridge University but often disagreed with his peer, noted a sperm bank in California offering only "elite" sperm, including from Nobel prize winners, had closed due to lack of demand.
