I would agree. Aluminum rims have far better braking performance than steel (although the OP says he has disc brakes, so that issue is irrelevant in this particular case), and are far less fragile and fussy than carbon fiber.
I'd instead put the blame on the modern fashion for low spoke count wheels, which require higher individual spoke tensions, exacerbated by he disc brake which put more stress on the spokes. Anodizing the rim also introduces a stress riser, as the anodized layer is more brittle than the underlying aluminum. As the late Jobst Brandt noted:
That they anodize rims is proof that no one is technically at home there. Materials science literature has ample publications concerning the fatigue susceptibility of aluminum parts coated with brittle porous hard coatings (anodizing). The aircraft industry, long ago, made these discoveries but the bicycle trade, that is mostly driven by fashion and managed by non technical people, must go through the long arduous process of first hand experience.
