The movie "Gattaca" did a good job of showing the bad place things could go if a movement towards designer babies was allowed to take off at the hands of government.

And that kind of brings a clarifying distinction that most people probably grasp: That it is one thing to say, "okay, let's use this to eradicate the hundred worst genetic diseases like cystic fibrosis and muscular dystrophy", versus on the other hand to say "let's re-design humans to make them five times as smart".

It is the second activity that may concern people most, as was brought to the screen in "Gattaca". And, sadly, there will be pressures for it to happen, just so long as we continue to have multiple countries on the planet competing in large arenas.

You kid yourself if you think that Canada is not involved in such competitions. From the eugenics programs of Alberta a century ago to 2017's immigration policy selecting immigrants with high education levels such as engineers and doctors, Canada is in deep.
