First when you have combination of factors, this can happen.

Second, old people were more likely to die on covid. Kids were getting covid too, just not dying and long term covid consequences were observed in then. It can easily be that where old person died, young ended up with long term consequence.

There is no reason to assume the effect would be uniform accross generations.

Either way, cell phone obsession and "rewiring of biology" claims are wven further from anything shown in the article. They are both purely what HN and the blogger want it to be.

I don't see your argument. Are you suggesting that covid pruned old people with weak memory to the point that it improved their memory on average? Because that is the only conclusion of your argument combined with the data. And that's not just completely unfounded, it's a pretty wild violation of Occam's razor.
