RE: Human / animal Hybrid
I don't think it's a non-issue. I do think that the politicians should be informed by ethicists within the scientific community and make their decisions based on that. I also think that every politician should be given a reading list of s/f and have to pass a public test based on that reading list before they are allowed to partake in the discussion. This debate has been approached from every angle in s/f books for decades.
I just know that most of the politicans are going to informed by religious and corporate lobbyists instead of scientists though. Instead of reading a genre of literature where there has been an ongoing discussion of the issue, they'll be looking at quarterly reports and religious doctrine written before we discovered science. Instead of talking to people who specialise in scientific ethics, they'll be talking to their shamen and men in $3,000 suits.
In the end they'll make all of the worst decisions for all of the wrong reasons.
