120 billion US Dollar was definitely not a small number for Future Group.
But if the 120 billion US Dollar was used to forge this key to the universe, then it would only just be a meaningless number.
After the completion of the space elevator, ignoring the 120 billion number, it would be a question if Future Group would use US Dollar for settlement. The aerospace industry would complete its leap from the Stone Age to the Bronze Age. The cost of entering outer space would be even lower than that of the civil aviation. The original unrealistic space mining would also become a reality. The changes to civilization would be described as world-changing.
And to achieve all this, only 120 billion pieces of paper would suffice.
