This comment misses that false-positive and false-negative rates are wildly different.
The rapid tests are still quite useful because a positive test is very reliable and saves you several days of waiting for PCR results.
Perhaps the test results should be labeled "Yes, you have covid", and "meh, not sure".
Rapid tests _always_ had bad sensitivity. Its gotten worse for Omicron, but going from "bad" to "worse" isn't really a big deal, because you never should have been relying upon negative test results anyway.
That's my point. The "use" of rapid tests was their "rapid" nature, coming back with a result in 15 minutes is way better than waiting for 3 days. The PCR is needed if you want to truly rely upon the result (well, kinda sorta. PCR got better sensitivity / specificity but its still not perfect).
