That’s a terrible headline. The prosthesis isn’t “controlled by thoughts”, it’s controlled the same way as the older ones, tapping to the muscles in the arm. The novelty they’re talking about is the hand being wireless.

This is so cool by itself, why the need to fluff it up with misinformation? The interview (that this article is just rehashing) does the same thing, with the daytime TV hosts insisting on the “controlled by thoughts” line even as both of the interviewees keep trying to correct the statement with accurate information.
