First of all, when we were in primary school, we learned the story of Edison inventing the light bulb. This is a great scientist, which is true, but it is also very bad. At first, he invented the light bulb, but it uses direct current, which is very expensive and can bring him great value benefits. Later, Tesla began to study the generation of electricity, and successfully found that alternating current would affect Edison's patent profitability, so he began to find someone to deliberately say that Tesla's research was murder for money. The danger was so great that no one was willing to do it at that time, but our life now is undoubtedly using alternating current, which is not only effective, but also cheaper.
Such a thing has directly delayed the development of electricity for many years and is a great obstacle to the social progress of the whole mankind. So Tesla is really smart and can propose to design such an inter-generational role, but he is not interested in money at all, otherwise the expert's research is fundamental. If he applied for a patent, he would instantly become the richest man on earth.
His research even designed the way of radio, the problem of crossing, and so on, and even cosmic weapons. This is his scariest place. It is difficult for such a young person to find such a clever idea. So Tesla is a seriously underestimated scientist. If it appears today, it is estimated to be of historical significance.
