The Fold 4 stylus is Wacom, not a "dumb" capacitive stylus if that is what you mean (unless you specifically bought that). Maybe you meant no recharging needed?
I was mostly talking about in contrast to the pro styluses that seem to have broader utility like a clicker, gestures and whatnot. I agree that this is not a capacitive stylus, I don't believe the writing fidelity and lack of lag would be nearly as good.
