Because, really, that’s where everything falls apart.
In the original, you can handwave that the programs whose faces you spotted earlier on users were written by that one user. Like, Alan is definitely coding Tron on his own. Clu (R.I.P) was written by Kevin Flynn. So w/e why not just say the old guy made his on his own, Lora made hers, Roy made his, and Dillinger seems too pissy to let anyone touch his stuff anyway. So okay fine.
But.. group projects.
I mean, best case scenario for the “bits and pieces” theory to work would be a group of people of the same sex (gender and how/if/when it would translate to the program isn’t something I’ve worked out yet), race, roughly the same appearance, and around the same age working together.
So all the brunette, tan, cis, caucasian, women are working on one program. Naturally (using the theory) their program would be a brunette, tan, caucasian woman. But maybe she’d have the slightly crooked nose on one, and the freckles of the other, and the more amber eyes of one as opposed to the chocolate ones of the other. But in all, she looks like their collective love child.
Let’s mix it up a little now. A blonde, a brunette, a redhead, and a ravenette are all working on a program. They all have varying body types. Maybe the program comes out curvy like one, with the green eyes of the other, and dirty blonde hair. Still, so far, so good.
But now it’s someone with green eyes and brown hair, one with red hair and blue eyes, another with blonde hair and brown eyes, a fourth one who’s got black hair and grey eyes, one with brown eyes and hair, and one who’s albino. And they’re all completely different in the rest of their appearances (some with freckles, some tall, some super thin, others curvy), all of different races, and also three are ciswoman and three are cismen. And one’s sixty and it shows.
Honestly, I think the rules of genetics apply here, even if there are more than two people involved. For example, if a certain trait has six carrier chromosome slots, and it takes at least four of the same for a trait to be apparent, and there are six people collaborating… Each person contributes one of the six, but it’s at RANDOM which of THEIR six carrier traits will be supplied, so there’s a chance that even if four out of the six contributors display this trait apparently, the product might still NOT if a non-apparent carrier trait is supplied four times or more.
If this is phrased in a way that doesn’t make any sense, it’s because it’s 2:30am and I worked two shifts today and I can barely focus on the screen in front of me. I swear it makes sense in my head, but I might need to revisit it later for proper rewording.
