Based on their AI chip presentation, the important thing is that they have a software/hardware integrated design relationship. Your comment assumes they do this once and never again.
I seriously doubt Tesla is not actively improving the chip, and if they need a fundamentally new software approach, then they have the process/iteration loop established.
