I've just started writing marginalia, after long feeling like that was desecration. It's been a revelation, and has transformed how I read. I'm much more engaged, and it feels more like a two-sided conversation than a one-sid

I don't think that argument holds. Usually it's true, that if something hasn't lasted a long time, it likely won't last a long time in the future. But we live at a quasi-special time, close to a boundary condition. There
