Title of the article you're commenting: Why Today’s Humanoids Won’t Learn Dexterity

Thesis the article is contradicting: The idea is that humanoid robots will share the same body plan as humans, and will work like humans in our built for human environment. This belief requires that instead of building different special purpose robots we will have humanoid robots that do everything humans can do.

You are now arguing that a specialized robot lacking dexterity would still be immensely useful. Nobody is disputing that. It's just not what the article is about.
