As a human I feel that having morality is very important, but moving all that stuff aside for a second, the only thing in the end that really matters is whether we will cause our own extinction.

Nature took a very long time to get us to where we are, it seems to me that playing with the biological building blocks at this level, relative to nature’s approach, has a very high risk of causing something catastrophic some time in the future.

The IT professional in me would advise to continue no further until a reproducible backup/restore procedure was in place. I’m not sure how exactly that translates to biological systems though.

Also I am currently available for hire :)
