The new fandangle wheels that use 12-24 spokes need a stronger (read more weight) rim so it is rare to find a rim other than carbon that weighs much less than 400 grams.

Yep, and the low-spokes win in the marketplace because they are "more aero" and because the newer riders have never lifted a 36 hole Rigida and would turn up their nose if they had the chance.
