The title "The Journey from EI to AI Mankind Redefined" was inspired by the profound shift humanity is experiencing as we navigate between the timeless power of Emotional Intelligence (EI) and the growing influence of Artificial Intelligence (AI). For Prof. (Dr.) Premankur Das, the title encapsulates the journey of balancing the deeply human aspects of empathy, connection, and self-awareness (EI) with the relentless rise of AI, which is rapidly transforming industries, relationships, and even our identities. Dr. Das, an experienced HR professional and academic, was particularly inspired by his observations in the workplace, where technology often threatens to overshadow the human touch. He recognized the need to redefine what it means to be human in an age of intelligent machines, while still holding on to the core values of emotional understanding and ethical leadership. The title reflects not just a technological evolution but a deeper philosophical journey—one that requires society to adapt while safeguarding the core values that make us human. Through engaging insights, Dr. Das offers a roadmap for navigating this shift, reminding us that while AI can enhance and transform our lives, it is our Emotional Intelligence that truly defines us. This book is an essential read for those seeking to thrive in a world where humanity and technology must coexist.
