You have too much faith in science. Scientists are highly fallible, and prone to making errors, as well as being corruptible by politics and corporate greed.

You have too much faith in science. Scientists are highly fallible, and prone to making errors, as well as being corruptible by politics and corporate greed. DNA is ridiculously hard to understand, and it continues to defy current theories. So, messing with DNA at this time is extremely dangerous, due to just how incomplete our knowledge of DNA is shown to be, and just how fragile DNA is in terms of resilience to random changes. The OP is case in point, as to where we currently are.
