Re: Putting restrictions on the genetically enhanced is very un-starfl
Personally I think the safety factor is a pretty valid reason for limiting the scope of genetic engineering. The "Khan" factor not so much. Mainly because the latter is frankly quite naive. It presumes that biology is destiny and completely ignores environment.
Ignoring nurture, concentrating only on nature is quite naive, yes.
But ignoring nature, concentrating only on nurture is equally naive.
Many human behaviours are clearly genetically (aka nature) conditioned; many individual human traits, as well. One could very well envisage creating a person so genetically predisposed to aggressivity that no amount of loving nurture could make a moral, peace-loving person out of him.
As a real world example, sociopaths; they may follow moral rules because society imposes and enforces them (by legal and social success means), but they don't really care about them, internalise them.
In the trekverse, as Archer said and 'Dr Bashir, I presume' confirmed (200 years later) creating someone with superhuman intelligence (even normal intelligence, as long as it's achieved by genetic engineering?) will in 1/2 of cases lead to increased sociopathy and aggressivity, increased ambition and lust for power.
And if in 200 years they weren't able to remove the flaws from the augmentation process, then these flaws are probably related to a fundamental characteristic of said process.
Would, in the real world, making someone far smarter than a baseline human make him a dictator-in-waiting?
I very much doubt it. But you can never know.
In the trekverse, though, the scenarists decided it does in at least 1/2 of cases (depending on nurture, presumably?) - probably because it gave them the villains in 'space seed' and then continued with the same idea; and because of inertia and not wanting to touch transhumanist themes.
In the trekverse, every time one tries it, one flips the coin - and sees what comes out from Pandora's box.
