Selfish patent

It is human nature to make mistakes, if we have to find mistakes from a great man who should not be judged by you and me.

There really is. Before that, you can search: Nicholas Trass. No, let me summarize: (What I said may not be accurate, and I almost forgot)

Society will always move forward, just like metabolism. At that time, Edison invented the lamp, but the lamp needed electricity, so he first developed direct current, and each unit of electricity cost money, which was a patent, and then Edison became rich!

~ ~ ~ (abbreviated as the genius childhood of Trass) Edison and Trass met quietly. Edison asked Trass to solve the problem of electricity (using DC), but Trass had found AC (better than DC), but he was forced to help Edison use AC and got 5w dollars. A businessman (forgot his name) was jealous of the great benefits brought by Edison's direct current. When he knew about Trass, he invited him to join his own company. Trass became rich, and alternating current was slowly born. Good and better can be compared. People are slowly discovering the benefits of alternating current, but Edison can't accept it. He still depends on DC to make money, so he experimented with dogs and cats to let people know the harm of AC (the electric chair was invented, a kind of torture device)! Trass also fought back, proving that as long as it is deliberately used as a weapon (that's what it means anyway, just like the game invented by us humans, as long as we don't indulge in nuclear energy and as long as we don't wage war), it won't harm people. Time flies from competition, and alternating current replaces direct current. But Trass didn't profit from it, and gave the patent to people all over the world ~ ~ ~ (Trass's second life is omitted, you can search for it yourself).

Without comparison, you can't see good or bad. Edison can't compare with Trass in character, and he is only evenly matched in talent.

If you are in college, you will be surprised to find that Edison appears in primary school textbooks and Trass appears in college textbooks.

The next language is a bit sensitive. Don't spray it if it's not pleasing to the eye.
