Is intervening in human genetics a natural progression of science, or is it an ethical boundary violation? I think it depends on the situation.
If it is used to help the advancement of science, solve genetic problems in the future, create medicine for serious illnesses, learn more about the human body, or produce healthier food, then it can be seen as a natural progression of science.
However, if it is used to make our bodies stronger, more beautiful, or faster than before, then it becomes an ethical boundary violation.
For example, imagine I am an athletic runner and I want to join a competition. If I use genetic technology to make myself faster before the race, it would not be fair to the other runners. That would clearly be an ethical problem.
For this reason, whether it is right or wrong depends on how the technology is used. It can be helpful for humanity, but it can also cross ethical boundaries if it is used unfairly.
