I’m OK with that.
The more time and effort I spend on my education, the more I realize how little I know. But the upside is I’m learning how little other experts know too, so it’s becoming harder to fool me, as long as I don’t fool myself.
If you are sure that lockdowns don’t work then you need to explain Vietnam, or Taiwan, or New Zealand, or states of Australia other than Victoria, or Victoria for that matter.
If you think this is a “casedemic”, and cases are decoupled from fatality, then you have to explain why an increase in cases predominately among an age demographic that doesn’t die from this disease should suddenly show a signal in deaths.
The reason we have more cases is likely partly because we’re testing more as can be seen from the total test numbers, but also from more cases as can be seen from the percentage of positive tests - it’s well described. You don’t get 30-40k new cases in the USA every day because of some accounting error, or because you have PCR cycles dialed up to 11 and are finding dead virus. You get it because you let an exponential progression get out of control.
The reason why the relationship between new cases and deaths has changed is because we appear to be getting better at keeping people alive longer. Plus most of the new cases are in people under 40, but that doesn’t mean these infections are harmless, they keep a reservoir out there for this virus to survive long enough to become endemic in humans, not to mention reports of long hauler issues.
You don’t have herd immunity until you have no reproduction … so claims of herd immunity at 20% are just empty claims, just numerology and reading of tea leaves. You’ll only know that you have herd immunity once you have zero reproduction. And there is no state in the USA with zero R₀ (and 4 in Australia).

I’m not certain that Ivor is wrong. I am certain that we don’t have the information to make the kinds of claims being made about the progression of this epidemic.
As Anders Tegnall (Swedens chief epidemiologist) said “Ask me if we did the right thing once we reach herd immunity”
