That is an extremely high-level statement that isn't worth making. Sure, Li-Ion batteries are generally pretty simple, and electric motors as an idea are simple. Making them work, at scale, and compete (or beat) ICE motors, while also managing to bring price down? Yeah, that takes decades of research. We've know about rubber for a really long time. It still took us many decades to make a good tire.
