Great post. My boss walked in while I was engrossed in my iPhone reading this.
The other interesting ethical question is clone rights. If I clone myself for spare parts or even clone a version of myself with limited mental capacity is it right to execute him and take his heart, brain kidney etc. I think we'll have to deal with this in next 50 years , maybe sooner.
Thanks. I think a clone of you would technically have the same rights as you. That said human cloning is banned in most of the world - in fact I can't think of anywhere it is legal.
