Vactor: There are probably
many reasons why we find playing games pleasurable in the direct reward-pathway sense, and in fact, I
do feel different after playing a mind-numbing, repetitive game vs. one that's somehow challenging and novel. Aside from that, the issue is less why you think you're doing it, and more an actual analysis of why you do it, and what is/isn't healthy. A dog will drink antifreeze for the same reason he thinks he's eating anything else (it's tasty), but that doesn't mean he gets the same thing out of it, or that he'll be neurologically rewarded/conditioned in the same way.
But without experimentation, how do you discover anything? Nobody's going to start with humans, they'll start with mice. Then larger animals, then human embryos, then humans who will live past the early fetal stage. Genetics is a very young science indeed, which is why we need people and organizations investing time and money in its development without worrying about irrational shit.
I wasn't arguing against controlled study and experimentation. I was arguing against letting it into the free marketplace unopposed and unregulated.
I mentioned this far earlier. Any genetic modification should be available to everybody, flat out. We have foundations working to distribute AIDS treatment, for example, to the poorer regions of the world. Same thing should happen here.
"Should" does not mean "will", and people have a right to be afraid until they can be damn sure that this
will be the case. Oh, and genetic modification of other organisms (plants, microorganisms, animals) is relevant to discussion and not without its own ethical questions.
