Seconds after some early adopters have shown that it works and has no side-effects?
Lots of people will argue vehemently about what it takes to be certain that there are no side effects.
Which could be a few decades after some early adopters tried it -- e.g. until they died in their 80s or 90s with perfect brain function...
So, seconds after that...
I suppose my point was that kornork seemed to me to be talking about safety and in that context, saying you'd do it after it is shown to be safe isn't saying a lot.
After all we do various kinds of brain altering operations and take brain altering drugs. DNA is not our personality, just how our body is built.
I disagree; there'll probably be a bunch of people who will vehemently disagree with "artificially" altering humans like this, even just to correct a genetic defect. They'll say it's "unnatural", or that it "isn't God's will", or somesuch.
I don't know that they'll be a big portion of the population, but they'll be out there.
