If you'd bothered to read the link I posted you wouldn't be throwing out a number like "80%".
We have about 500,000 cases in the US (known)
I posted evidence that we may be seeing about 50% of cases being asymptomatic (there's a lot of wiggle room in the 50%, but that give you at least an order of magnitude).
Now assuming all 500,000 cases are symptomatic (they're not, but we'll let them go in the wash for now) then we're looking at maybe 1,000,000 total cases in the US. Which has a population of 350,000,000.
So our best estimate would be that we're at 0.3% have that "herd immunity".
It's dumb to say "we could be at 80% and have real herd immunity". Like... not even understanding the magnitude of difference dumb.
Let me break down the dumb.
for there to by 80% herd immunity at this point, we would have had to have 280,000,000 cases in the US. With 500,000 cases detected, then we would have a symptomatic rate of 0.1%. Literally, one person in every 1000 infected would show symptoms. That's.... practically undetectable. Those cruise ships, at 100% infection rate, would only have 3 people show symptoms. That's simply not reality.
