However, in many Low and Middle-Income Countries (LMICs), connectivity remains a challenge.

To address these limitations, ChatGPT is optimized for low-bandwidth environments, while Gemini leverages its seamless Google integration to maintain performance in areas with limited resources .

These patterns highlight broader shifts in technology adoption. As Aparna Bharadwaj, a global leader at BCG, points out:

"Many business leaders that I've spoken with assume that their technological changes are invisible to consumers. But the opposite is true when it comes to [generative AI] in particular."
