It's with us. We have it. What does this truly mean? I don't know...but I do know that it will be 'fun' to watch the backlash.
The technique is not yet workable, but scientists have genetically engineered non-viable human embryos that produce stem cells matched to a donor. One more step...stripping out extra DNA these cells carry...needs to be perfected before it can be used.
But will it? This will be the next target of those who think all 'human life' is something special, even human life with no chance of surviving. For that matter, I'm not even entirely sure what I think about it myself. It could be a slippery slope.
But we have to accept that 'playing God' is, and always has been, what humans do.
