Nero failed where Epicurus succeeded because Nero neglected to practice the philosophical principles he preached, while Epicurus did not.
Nero was a hypocrite, who pretended to be virtuous. His true character revealed itself in his later life.
Nero's cruelty, greed, and lust for power led him to commit the atrocities that made his name infamous. While there may have been some good in Nero, even a small amount would have enabled him to be successful. Instead he let his vices dominate.
Epicurus, on the other hand, was a role model. He lived his philosophy and practiced what he preached.
Epicurus was a humble man, who sought to help others. He lived simply and in poverty.
Epicurus was kind, and did not desire material wealth. He lived a life of virtue, and aspired to wisdom rather than power.
You are getting an AI to generate text on different topics.
This is an experiment in what one might call "prompt engineering", which is a way to utilize GPT-3, a neural network trained and hosted by OpenAI.
GPT-3 is a language model. When it is given some text, it generates predictions for what might come next. It is remarkably good at adapting to different contexts, as defined by a prompt (in this case, hidden), which sets the scene for what type of text will be generated.
Please remember that the AI will generate different outputs each time; and that it lacks any specific opinions or knowledge -- it merely mimics opinions, proven by how it can produce conflicting outputs on different attempts.
