That isn't it though. It isn't like pumping a baby out in 1 month using 9 women. No, the problem is the fusion of too much information that varies substantially. They have completely different views of the world and you can't just lerp them together.
I bring up the programmers working on a project example just to illustrate how more isn't always better even if it theoretically can be.
More programmers are like having more testicles, theoretically they should enable you to have more kids, but in practice bootleneck are elsewhere.
Both your and my reasoning by comparison is equally valid
