It's an important question to ask.

When I read "What if all 89 voices said the same thing?" I thought I understood the thrust of the article; that overpersonalisation creates an echo chamber devoid of the dissent and reflective views that allow people to make their own minds up and that therefore overpersonalization has insidious potential.

I was dismayed to find that "What if all 89 voices said the same thing?" was seemingly being asked as if the answer was obviously "Oh God yes where do I sign up" (and I do understand that their target audience would likely reply as such).
