Herd immunity threshold (H) is defined as the minimum proportion to be immunized in a population for elimination of infection.
H = 1 - 1/Ro = (Ro -1)/Ro As the immunization coverage increases, the incidence and prevalence rates may decrease not only due to the direct effect of immunization per se but also because of indirect effects, such as the development of herd immunity and herd effect
Do you know anyone who has had polio?
So we are back to anecdotes? Your disorganized thinking is sad to watch.
There is eradicated in that it doesn't exist any more and then there is eradicated in the sense that only some statistically small number of people get it.
COVID was not eradicated and considering how infectious it is, could not be eradicated with mRNA treatments due to how they function. Hint:Any rational argument must show how any treatment or vaccination program could lower R (basic reproduction ratio) to 1.
And unfortunately, thanks to the games like this we ended up with things like the "Verifying that you are a human" interstitial pages from cloud flare, which I am guessing use something like described for Anubis. I hate it and my CPU hates it (spiking to 100% for up to a minute to perform the calculation). You know who doesn't hate it? The bots. They simply act like any browser that has no JavaScript and ignore it.
Oh, and my Noscript (different device) breaks those pages every single time, meaning that I move on to a better source.
What is the worst a 'communist AI' could do
Your lack of imagination does not mean this is not a huge problem. The issue with Cmmunist ideology is that it is not logical, but it could somewhat work because people can ask in a rational ways within irrational system. AI, incapable of reason or logic, would just rigidly apply its parameters, which in case of Communism will result in mass casualties. This is because Communism is a poor model of reality.
You're still here after all these years?
Notably though if we actually run out of work to do we have a post-scarcity utopia, and that happens when people are so rich that there's basically not a single person who, given even more money, would even be able to think of something to spend it on. That's not going to happen any time soon, so we're basically dealing with a distribution problem, which requires distribution (e.g. minimum wage, set it to 1/3 national hourly GDP, the reason for this takes a while to explain) and redistribution (negative income tax, do it as a universal dividend) policies along with monetary policy to properly increase the money supply to not fall behind productivity growth.
To see a need and wait to be asked, is to already refuse.
