A king once summoned a wise man who had done him a great service and said, “Name your reward.” The wise man replied, “Your Majesty, I ask for a simple thing. Give me one percent Linux desktop market share for the first square of the chessboard, two percent for the second square, four percent for the third square, and so on, doubling the amount for each of the 64 squares.” The king, thinking this was a modest request, said, “Surely you jest! Such a small reward for such a great service? Ask for gold, land, or jewels instead.” But the wise man insisted, and the king agreed. The king ordered his treasurer to calculate the total. Starting with 1% for the first square, 2% for the second, 4% for the third, 8% for the fourth… by the time they reached the tenth square, they needed 512% of the desktop market. The treasurer, pale with realization, informed the king that by the 64th square, they would need more market share than could possibly exist in the entire universe of computing devices. The king then understood that what seemed like a humble request was actually impossible to fulfill, and he gained a new respect for the power of exponential growth.
In the original it also supposedly amounts to more grain then there is in the kingdom.
