I guess I always assumed - perhaps wrongly - that not all augments are as odd as the Jack Pack. I thought that the members of group are simply the augments that didn't turn out well, and that meanwhile, there are other augments that were more like Bashir, being quietly and inconspicuously brilliant with most people of the people around them being unaware that they had been augmented. It doesn't seem likely that Bashir was the only really successful augment, does it?
But if this is specifically addressed somewhere, I do hope someone can enlighten me.
There could be successful augments all over the place. We have no way of knowing. There may also be many more 'defective' augments out there that simply aren't known to the authorities as being augments - everyone may just think these people are naturally 'off'.
However, the success vs. failure rate isn't why the Feds would outlaw it. ANY 'failed experiments' would demonstrate the entire affair to be unethical in the UFP's eyes - mucking around with a child's DNA without their consent, etc. I wonder what the UFP's stance/law would be concerning adults who choose to augment themselves (a cyberpunk literature mainstay)? They're not hurting anyone else...
I think an interesting episode premise would be an entire planet of people who abandoned the Federation and decided to go hog-wild with augmentation-ism, and what the consequences were, what issues are raised, etc. Maybe it has been done in Trek, I can't recall. There were the Angosians from TNG's 'The Hunted' which featured 'super-soldiers' that were cast out from society because, due to their enhancement, they were considered unable to coexist with normals - but that was a case of people specifically being engineered to be soldiers, not a more general enhancement of intelligence, memory, and what-have-you. (And arguably, creating the perfect soldier doesn't include intelligence enhancements - you want them to follow orders, after all, not be so clever that they dare to think for themselves!)
I'm going to throw out a recommendation for an excellent, excellent trilogy of novels by Richard K. Morgan - Altered Carbon, Broken Angels, and Woken Furies (should be read in that order). The stories take place in which every person has something called a 'cortical stack' - something the size of a pencil eraser - implanted in the base of their skull at birth. The stack backs up their entire consciousness, all the time, in real time. When you die in that universe, your stack can be downloaded into a new 'sleeve' - AKA, body. People don't travel through space in ships; they 'needlecast' (aka transmit) their minds between planets (the planets were first colonized by slower-than-light ships carrying terraforming robots and stored embryos with cortical stacks of the 'colonists' who left and were 'reborn' on the new world in new bodies).
Due to the fact that minds can be 'downloaded' into new bodies, there are many types of custom bodies ('sleeves') available on the market for a variety of purposes, ranging from genetically engineered, cybernetic, or completely synthetic sleeves. The three books follow one character, on three different worlds, in a variety of different sleeves, and each one is very different. In the first book, he occupies a body that was previously occupied by a smoker - so during the story he's struggling to quit a smoking habit that he didn't possess in the first place!
Anyway, let me get to why all this is relevant to the discussion - in the second book, the main character is fighting as a mercenary among a platoon of other mercenaries-for-hire, and they're all wearing the same 'brand' of 'sleeves'. These bodies have been engineered with something called the 'Wolf Gene', which gives them a near-psychopathic ability to wage war and do damage without feeling much empathy for the opposition, but also gives them a wolf-pack like mentality as far as each other is concerned, so they're a very tight group as soldiers. When another member of the 'pack' is killed or wounded, the main character has to suppress a wolf-like keening in his throat due to the overwhelming emotions he's feeling.
Part of what makes these books so great is the questions it raises about personal identity that one possesses (or doesn't) under these conditions. The main character is special because he's been specifically mentally trained/disciplined to operate in whatever body he's given. He's a soldier whose consciousness might be 'beamed' to another planet, where he'll find himself in a strange body on a strange world, and must maintain his discipline and training in whatever body he's dumped in - but even he, being one of the 'mentally elite' (physical training is worthless when one won't have the same body!) faces challenges and identity issues when put in a strange sleeve and has to face a stranger in the mirror and deal with the baggage that an old sleeve carries.
I feel that the UFP's stance on augmentation is for similar reasons. When someone is 'augmented', they're not necessarily just the same guy or gal on the inside with new and different abilities - you're fundamentally changing who they are, in wild and unexpected ways. Bashir may have been a successful doctor and an all-around good guy in the end, but the moment his parents decided to augment him, they more or less sold him into slavery. There's no promise that augmenting his abilities simply left him as the same Julian Bashir and added more capability. His ambitions, desires, dreams... his entire consciousness would have been unavoidably altered to the degree that he
wasn't the same man that his parents gave birth to. It's easy to say that it's okay, because everything worked out because he was successful, but that's tantamount to endorsing the horrid real-life forced lobotomies and the like of mental patients of the early 20th century because they were 'more well-behaved' in the end - or, to introduce a more contemporary/topical issue, the administration of Ritalin (and the like) to arguably intelligent but so-called 'hyperactive' children, which may make them 'better', more well-behaved students but simultaneously excise a genius, multi-tasking capacity that would be damned useful in maturity. Who's to say the original, unaltered Julian Bashir wouldn't have had a successful, happy life, even if it was as a hover-truck driver on Alpha Centauri, rather than a physician with a longing to practice frontier medicine?
And, most importantly, who could claim, with certainty, that he would not have become a
better doctor (or whatever)
without the augmentations? For all anyone could've known, he could've been the future President of the UFP. He was never given the chance.
