Every generation somebody shows up at says, clean sheet esin or rebuilding all this. So now we've got at microfactories, composit materials, some modularity to your batteries and vehicles. There is already a very large advantage on the teho platforms and the time that woull take for anybody to recreate the system. At the same time, i would encourage people to use the micro factory. And there's no reason why every layer of technology that we've built in thi system isn't something that can be shared with other folks.
