● Why 'Mentors' are Needed Exactly Because it's the AI Era
With the development of AI technology, we are in an era where anyone can easily obtain information. However, for this very reason, it is becoming important to enhance 'human power' (the improvement of oneself as a person and the exhibition of charm). AI provides correct answers, but only flesh-and-blood humans can elevate the fundamental sources of human dignity and creativity.
Looking back at history, Sakamoto Ryoma learned from Katsu Kaishu, Oda Nobunaga from Takuenzu Soen, and Tokugawa Ieyasu from Takeda Shingen, and each achieved great deeds that left their names in history. What they learned from their mentors was not merely knowledge or techniques, but a way of life and judgment as human beings. Because today is the golden age of AI, the value of learning from a mentor who is a flesh-and-blood human is being re-evaluated.
● Choosing a Mentor Changes Your Life 180 Degrees!
