The Legend of the Chessboard: The Power of Exponential Thinking

Once upon a time in ancient India, a wise inventor presented a new game—the game of chess—to his king. The king was so delighted by its brilliance that he offered the inventor any reward he desired.
To the king’s surprise, the inventor made a humble request:
“Majesty, give me one grain of rice for the first square of the chessboard, two grains for the second, four for the third, and so on, doubling the amount for each of the 64 squares.”
Amused by the simplicity of the request, the king laughed and quickly agreed, thinking it was a trivial reward. However, what seemed like a modest wish soon turned into a mathematical marvel.
A Surprising Reward Unfolds
At first, the king watched as his servants placed rice on the board.
1 grain on square 1
2 grains on square 2
4 grains on square 3
8 grains on square 4
By square 10, there were 512 grains—barely enough to fill a small bowl. The king smiled, assuming the inventor’s request would amount to nothing substantial.
But then the numbers accelerated.
By square 20, the total exceeded 1 million grains.
By square 30, the board had 1 billion grains—requiring entire storehouses of rice.
By square 40, it reached 1 trillion grains, and the kingdom’s granaries were emptied.
By the time they reached square 64, the final number was unimaginable:
18.4 quintillion grains of rice—enough to bury the entire kingdom in rice mountains larger than Mount Everest.
The king was stunned. What he thought was a trivial request had multiplied into an impossible fortune. At that moment, he realized the true power of exponential growth.
This story is more than just a lesson in numbers; it reveals a profound truth: small beginnings can lead to astronomical outcomes.
Exponential Growth in the Modern World
This isn’t just a math trick—it’s the same principle that is shaping business and technology today:
1. AI is improving at an exponential pace, transforming industries overnight.
2. Startups scale from 1M to 100M users almost instantly (think ChatGPT!).
3. Investments compound over time, turning small amounts into massive wealth.
4. Technology adoption is accelerating, disrupting entire industries in just a few years.
The lesson? Small improvements, when compounded, lead to massive breakthroughs. Businesses that embrace exponential thinking—leveraging AI, automation, and network effects—can unlock game-changing success.
