Let’s say, hypothetically, that it was as bad as 50% false calls, 50% calls that wouldn’t have been made, and that every false call is missing a real call. That’s break even. That means 1 person loses access to emergency services and 1 person gains.

Any better than that and you’re helping more people than you hurt. Obviously the ideal is perfection, and not having any false calls, especially ones that take resources from real people. But it doesn’t take amazing accuracy to improve the net outcome.

If you get data that they’re more likely to be incorrect than a normal call, you can change your prioritization to prioritize a human speaking. Apple can continue to improve their accuracy to minimize false positives. But those improvements are from a situation that’s already better than it not existing.
