A common principle in Christianity is that the world is broken beyond repair. Generalised from the principle that everyone is a sinner.
That's why signing up for redemption is such a Big Deal. Either you are on the Christ bus or you're stuffed.
(The exact reasoning varies from church to church, sometimes a lot).
It might or might not be relevant, though. The linked article actually (sorta[1]) suffers from another common problem, which is that the world is a rational machine that can be "fixed" with a few architectural changes. It's very common for intelligent people to think that way.
Complex systems don't work that way. In fact, the best we can do is intelligent trial and error. Treating people as a physics problem or an architecture assignment tends to end in tears.
[1] Another way to look at is that the author has restated the old observation that technological solutions can't solve social problems.

No, I'm not implying religious belief means that the OP is dumb. I'm saying that Christ-centered theology argues for a fallen world based on immutable characteristics of mankind's nature. Given this, I can see why the OP is inclined to think that no real change will come from "your app" or any other man-made thing.
