Humans have been searching for the ultimate since the inception of humanity.
For most of the human history the ultimate truth relied on religion.
If you were born in a Christian family, the ultimate truth might be you were born of sin. There is a heaven and hell. And you need to be good in this life.
If you were born in a Hindu family, the ultimate truth might be of reincarnation and end from suffering.
And for buddhists it’s enlightenment. The end of suffering by breaking from illusion of a separate self.
If you are philosopher the ultimate truth might be pursuit of knowledge.
And if you are the founder of an AI company the ultimate truth is saving humanity from dangerous AI that might kill us all while at the same time raising trillion dollars to fund it.
