Which famous foreign scientist was conceited and stopped inventing in his later years?

In his later years, Newton thought that "God" was an eternal, infinite and absolutely perfect master. Newton tried his best to find the argument of the existence of the so-called "God" in celestial mechanics, and worked tirelessly to serve the "God" faithfully. According to historical data, in the forty years from 1687 to his death in 1727, Newton studied "alchemy" and annotated the Bible enthusiastically, and consciously used natural science knowledge to publicize his teachings. He completely violated the original intention of studying science for the benefit of mankind in his youth. Newton firmly believed that the orderly movement of planets around the sun was due to the first driving force of "God". In order to "refute" the "fallacy" of materialists and atheists, Newton actually provided all kinds of arguments for "the existence of God" in a speech entitled "Refutation of Atheism" on the "Science Platform" given by Bentley at the request of the priest. A great scientist with a high reputation in the world actually cheered for "pseudoscience" and declared that it was to fulfill "the responsibility of scientists"! How absurd and pathetic this is!

Edison was a great inventor in human history. After only three months of formal education, he finally obtained more than 1 invention patents. However, in his later years, Edison was no longer determined to make progress. He once said a sentence that stunned us: "Don't give me any advice in the future, because any of your ideas have already occurred to me."

in 1882, after the incandescent lamp was completely recognized by the market, Edison's electric company began to establish the power grid, thus beginning the "power age". Edison's electric company relies on direct current to transmit electricity. Soon, AC technology began to emerge, but Edison never recognized the value of AC. With his prestige, Edison gave speeches everywhere, spared no effort to attack alternating current, and even publicly ridiculed that the only purpose of alternating current was to make an electric chair to kill people! This made westinghouse Company, which developed AC technology, unable to lift its head for a time.

but a moment is not equal to a lifetime. Later, people who worshipped Edison were surprised to find that alternating current was actually much stronger than direct current in the face of iron facts! So people became angry, and the employees and shareholders of Edison Electric Company were even more ashamed and decided to delete the word "Edison" from the company name.
