People were flying well before the Wrights in various ways. In fact, copying others successful glider flights was the starting point for their first glider. I think there was already a patent on ailerons well before 1903. Other people were already making engines and some specified the same specs as the Wright.
Point is that aviation has always been a “parts bin” of other technologies and “inventing” is mostly just having enough of other people’s products and tech at hand. The same with EV aviation. Aviation will not be inventing batteries any more than the Wrights invented sailcloth or internal combustion. EV planes will not supplantalong, not before.
