All data is inaccurate to some degree. This is not new.

There are ways to mitigate false positives, and many of the best SAAS work tirelessly to constantly incorporate every new update and every new technique to try and correct data to make it as clean as possible.

We're not sending people to Mars. And even then, every measurement has a margin of error. It's the inherent nature of measurements.
