This is the tradeoff of the Apple ecosystem. For most users the trade off is a no-brainer because they don't care about the theoretical concerns that, in expectation, do not apply to them. I mean, what is the probability of this technology causing an innocent user harm? 1/1,000,000 ? 1/10,000,000? 1/100,000,000?

According to Apple, 1/1 Trillion chance of a false report per year.

So the chance for a single photo to be incorrectly matched is much higher. But by setting a threshold at ~30 images before triggering a manual review, they get the odds extremely low.

My bet is that error threshold will remain a constant for them. As tech gets better, they will reduce the threshold accordingly to maintain that error rate. In five years, I’m guessing they will only need three images to trigger a review.
