difference between knowing how to and actually doing it? Is it the theoretical science is known, but

building it into hardware is the issue? Or, like, where where is that gap? When I say we like, knowing how to do that versus not, it means that it becomes a problem of refining the engineering. But we understand that a given solution will reach a particular performance or a particular scale, but it requires, say, multiple iterations of the same architecture, let's say. The same material. The same like, just refining the engineering, better engineering, understanding the system better and better, but we we know that it will reach it. That's what I would call an engineering road map. You know, in the same way as, like, classical industry companies,
