|You have to think about this in terms of who these people are. The Silicon Valley people.|
You can take a perfectly moral human being... but when it comes to their kids, people will do anything, anything it takes, to give them the advantage it takes to survive and indeed stay ahead of the pack.
For the people in Silicon Valley it will become a race, those who are in early will have a huge advantage because everyone else will be trying to keep up with the logarithmic advances. They will come to the conclusion that everyone else is doing it. It can't be stopped by laws, since it will happen world wide, and if need be underground like the dark web. Kids who are not genetically altered will become doomed. Its going to be a life or death war of intelligence and power.
And they have the money. The desire and quest for money will also accelerate because the competition for the best of the best of genetic engineers will be crucial.
