I've posted before that the difference between COVID brain damage and LLM psychosis/cognitive damage is almost impossible to disambiguate, because both have risen in society at essentially the same rate at the same time.

And now that we basically don't have a NOVID population to study against one with multiple infections, it's going to be hard to ever figure out which is contributing more to the sudden shifts we see in some people.

But, like - don't sleep on the COVID aspect.
