Imagine in 5-10 years where, just like people make video games all by themselves or with a small group of people, people can make their own movies that rival Hollywood productions, for a fraction of the cost as there's no need to hire anyone. When the output is just pixels on a screen and you can manipulate the placement of every pixel, it's really no different to Hollywood making them with real actors and crew members or someone drawing them, as is the case with current animation methods. Now, we can do the same process as drawing each frame but then make it look photorealistic.
