I've posted a reply to this in haste, but it was a bit more emotionally charged than ideal. This is a reworded version that I believe reflects my thoughts more accurately.
> The fact that you don’t see the downsides of manipulating atoms, and the trouble is causing in this very day with the risk of nuclear war, literally proves that we are not that smart.
That is a very far removed interpretation of what I wrote. As I'm sure you're aware, nuclear bombs operate on fission (or in rarer cases, fission and fusion). These are atomic-scale processes, but do not involve atomic-scale control (or in some cases, even control at all - natural fission sites exist). A more faithful example for what I said would be semiconductor manufacturing, where the state of the art is 40-atoms wide tracks of patterning resolution. The atomic pick-and-place I describe was demonstrated, but has no practical implementations that I'm aware of (would be way too slow). But even if we go back to fission, nuclear plants are providing stable, relatively clean baseline power at reasonable costs, and for better or for worse, the world didn't yet descend into WW3 either, and it's more than fair to speculate that this is due to the temporary checkmate nuclear bombs provide us. So as far as I'm concerned, no, I think we're pretty alright still.
> Everyone’s assumption are that these genes that are killing these children are “bad“.
But your position doesn't seem to care much for if this assumption is correct or not. Even if it's bang-on perfectly correct, you stated that this is eugenics period, therefore it's bad. Was that not what you meant to suggest then?
> They know these jeans survived thousands of years of evolution for a reason.
How would you know? What if I disagree that reason and purpose are ontologically real?
> Human genetics cares about our survival, it is totally a moral.
I disagree that human genetics would be a conscious process, and that it can thus care about things. I also disagree that it can know anything about morals - morals are a human concept, and they're not even universally shared across us. Very clearly just the two of us seem to hold ourselves to very different definitions of what's moral, for example.
> It would rather a few babies die so that hundreds could live.
I don't suppose you're claiming that this treatment (or other genetic treatments) result(s) in the vast majority of the patients dying?
