changing genes is wildy unpredictable. we don't know a tenth of what the human genes do, let alone know some functions of the human body.
i read a short story years ago about the dangers of gene alterations. don't remember who wrote it, i've forgotten some details of the story. in this particular future, the population of earth was wiped out by a gene virus that got out of control. People were altering themselves in different ways, remains were found with tails, others with wings, etc... I think it was some explorers who found a monument erected by the survivors.

CRISPR technology is a simple yet powerful tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function. Its many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops.
But you are right about not completely understanding what all our genes do but the science is advancing so fast at a rate never thought possible just like it was thought we wouldn't have a Covid vaccine for another year.
We do know that some ( very few humans ) feel no pain and that is related to a gene. When we, if we haven't already, find that gene and understand what is missing, we simply change that gene and create a human that can not feel pain. Imagine that ability in a combat soldier.
I can easily imagine that in another 20 years or less, we will be able to eliminate most if not all genetic based disease. The question being asked now by ethicists, is should we. Of course we should IMHO.
