What if...

- covid is essentially a death sentence that kills 2-10 years after infection, as with HIV/AIDS;

and

- the shots were never meant to help OR hurt people, since they were doomed anyway, and were just a way to extract some value from the doomed before they die;

and

- the primary value being extracted is Big Data on how human bodies and brains work, which can then be used to train AI to be able to use that knowledge and make the bodies/brains of the elites somewhat immortal and capable of interfacing with the AI.

I think of how the communists would take individual mugshot pictures of the millions of prisoners before they were executed, and it seems like injecting doomed people with self-assembling nanostructures/biosensors might be the modern ultra-high-tech version of that old practice.
