This book explores the multifaceted concept of engagement in the digital age. It begins by delving into ethical engagement, covering the responsibility of influence, digital well-being, the digital divide, combating misinformation, regulatory innovation, corporate social responsibility, and building trust in digital platforms. It then shifts to engagement in non-digital spaces, examining the transformation of education and work in a hybrid world, and civic engagement. The economics of engagement are analyzed, including the immersive web, emotional AI, the sustainable attention economy, and future trends. A significant focus is placed on building an attention-resilient society through mindful practices, digital well-being education, policy interventions, and rethinking digital engagement models. The conclusion synthesizes these themes, highlighting the challenge of the attention age, forces shaping attention, practical steps for ethical engagement, and a hopeful vision for the future.
