Except lungs are, arguably, a minor (just most visible) issue with COVID.

We're going to deal with long history of disablement caused by how COVID attacks neural tissue, for example, something I think might be more disastrous long term (1918 flu was similar, with some historic effects like Aktion T-4)

You haven't provided any evidence of a link between the 1918 flu and the Nazi Aktion T-4 mass murder program.

Essentially, a significant portion of "invalids" in Germany that Nazi targeted first were people impacted by 1918 flu, specifically those who were exposed to it in prenatal stage. This contributed towards the Aktion T-4 program, and one of the common long term effects of the flu was among the targeted diseases, outside of just increased disability counts in German population due to 1918 flu.

Reasonable starting point for looking further:

Your cite says this: "Despite extensive distribution of SARS-CoV-2 in the body, we observed a paucity of inflammation or direct viral cytopathology outside of the lungs."

Ah, and I see the tweet is trying to dispel fear that was worked up around this. Got it.
