I saw the same thing. It seems one of T'Challa's powers is power seep instead of power creep. They need a seen in the next movie where T'Challa corrects Shuri on something tech related or some such or movie goers may never see it. I liked the movie as well, and they did low key showcase T'Challa and his various gifts, but I really had to watch. Casual fans will miss it.
