In "Safe to Great: The New Psychology of Leadership," author Skip Bowman delves into the profound transformations shaping the modern workplace and society through four distinct epochs: the Green Age, the Globotic Age, the Caring Age, and the Digital Enlightenment Age.

The Green Age focuses on the existential threat of climate change, advocating for global awareness and action inspired by historical environmental movements.

The Globotic Age addresses the impact of globalization and artificial intelligence on employment, suggesting a shift towards 'new smart' skills that prioritize creative and collaborative abilities over mere knowledge retention.

In the Caring Age, the emphasis shifts towards healthcare and mental well-being, reflecting on the societal challenges posed by aging populations and lifestyle changes.

Lastly, the Digital Enlightenment Age explores the ramifications of technological advancements in social media on privacy and misinformation, highlighting the need for balanced progress that safeguards personal and collective freedoms.

Bowman argues that these eras demand a revolutionary approach to leadership that establishes psychological safety and promotes adaptability, learning, and growth amidst these sweeping changes.
