A sleeping giant is the Tesla dojo multi wafer, call it a silicon system in a cube, project which we do not have public visibility on the creation of more cost effective electronic brains to do the heavy lifting for current and new projects. While we are aware of shadow mode vehicle processing I expect dojo clusters to become the hardware robot brains possibility for AI-6 assuming good manufacturing progress and yields. It makes a lot of sense to expand core and distributed processing solutions.
