I use a physical notebook but not really an engeneering notebook as described here.

I make notes while working and notes during meetings. Honestly most of it never gets read after a eay but I still do it.

Very few of my colleagues carry a notebook around. Those who do are not seen taking notes too often.

Almost all my paper notes these days are write-only media.

The benefit is not the artifact itself, but the immediate act of formalizing the idea, emphasizing its importance, and being mindful/attentive to what's going on.
