Gene therapy on human embryo..

For the first time through a process called CRISPR a human embryo was manipulated to correct a gene defect. So the question arises if we humans are playing god and altering the course of evolution?

And the answer is YES, we have done so for a long time.

We have come to appreciate many different forms of human lives. We have started to help humans with gene defects to survive where before they would be without hope and die at a very young age. So we have altered the course of nature when we decided to not let natural selection of the fittest apply to the human race. We bestowed it upon ourselves to play god long before we started to manipulate genes directly.

If in the long run we allow the survival of the fittest to not apply then the human gene-pool will deteriorate over time. In times way past being farsighted was a sure way to not seeing the predator soon enough to survive long enough to reproduce. So that kept farsightedness under control. If we not all want to end up farsighted in a few tens of generations it is best we do something about it. Current fix is to laser the eyes after they stopped changing in early adulthood. But if this is hereditary then wouldn't it be nice to change this even before one is born (given that there are no negative side effects)?

Ultimately humans will need to get comfortable with repairing what we have rightfully allowed to exist and proliferate. There is no other way of saving humanity from all becoming a lump of defective cells.

If we play god in suppressing natural selection then we better also play god in cleaning up the effects of our actions.
