What are you building?
I want to dig a subterranean passage.
Some progress must be made.
My station up there is much too high.
We are digging the pit of Babel.
(Franz Kafka)
A remark I made yesterday concerning my disappointment in 21st-century skyscrapers (when buildings finally reach a height of two miles or more, opinions may change) was countered with the hope for an even greater achievement: a building two miles deep.
Frankly, I would prefer the natural light.
And so the process of creation begins.
2 miles in vertical direction seems like lots. Either upwards or downwards. I would rather dig a cave into the side of a mountain. or under the sea than vertical.
