I've been quite fascinated by the relative insignificance of human existence, the shortness of life. We might as well be a letter in a word in a sentence on a page in a book in a library in a city in one country in this enormous universe! And that kind of fear and insignificance has kept me awake at night.
I know there are lots of positives in the evolution of technology, but I also think it will be responsible for the end of a unique character, of a specific kind of geographical culture. The world is getting so small, and mass production is getting so big. Everything is in danger of becoming the same.
