It is a pity that the girl's invention has been ignored. Many inventions in the history of this world went unnoticed and hidden for a long time, even for centuries. Most of them were too advanced for their time, and have only been recognized much later. A specific example of this is that of the famous inventor who did not get the necessary recognition when he should have, and that only came long after his death... Sometimes I imagine the many inventions that would have come later or if perhaps today there would not be those poles with power lines that sometimes obstruct the view of the landscape.
