DNA technology - an ethical dilemma
"DNA manipulation", augh, a concept with bad connotations. It's know for many public discourses about modified corn and the first cloned mammal, the Sheep Dolly. It raised the ethical questions about DNA technologies again and again.
There isn't really a "wrong" or "right" on this topic. More a hope about what could be and a fear what shouldn't happen.
On one side you have the obvious benefits you would have by allowing DNA manipulation like Crispr. You could heal many known diseases like Alzheimer and dementia. Furthermore you could even prevent these and create humans with perfect health.
This is also where the fundamental problems lie. DNA manipulation and it's ethical questions aren't a problem in the future. The future is now. So it is only a matter of time until some malicious actor will use this technology for malicious matters. Why not create a deadly virus only my opponent is affected by? And when this gets available to a broader mass it will create a divide again between the poor and the rich who can pay for these surgeries.
So it is crucial to create a rigorous ruleset which leaves no place for error, literal lives are depending on it.
