It's amusing how people will constantly see Animoji as a use-once-and-then-never-again feature, calling it virtually useless. But what they fail to realize is the research, development, and engineering that went into creating the feature — that same technology opens up so many doors in so many new ways. So while Animoji may be a fun feature on the surface, it's a big step forward for 3D camera technology. We haven't even seen the half of it yet.
