The concept of creating superhumans using genetic engineering has been around for quite some time in science fiction
, but now that it's almost becoming a practical thing to do, there are some scientists calling for a moratorium
on experimenting with germline engineering until we can debate the issue and come to some consensus on what should be considered ethical. Treating diseases with drugs/radiation/whatever may let an individual patient live longer, but messing with embryonic DNA could have more lasting effects because whatever genetic edits are made will be passed down to future generations (well, unless genetically modified humans are purposely made sterile...). This kind of medicine is going to be controversial for the foreseeable future, but it's going to be done somewhere as the science and technology behind it gets better.
