CODING feels like the first and easiest step it could take after solving natural language so it is taking the path of least resistance to what it can understand at the "neuro" level.
What's next for it to understand? probably spacial/geometric and mathematical relationships. It's not so good at those still. That will likely take CAD and 3D modelling out pretty quickly etc.
The other thing we are seeing is instead of training it to understand these concepts, just build things towards what it already knows like code and natural language. That is why so much software now wants to have all their stuff be able to be build using code.
