Humans didn’t always exist, nor will we exist forever. Which is why we must invent.
— From Dumb Type’s S/N (1994)

My first encounter with S/N came when I was 18 years old. I remember the day well. I was waiting, as always, at Shibuya Station to catch a bus to school, but I just didn’t feel like going that day. I left the line of students and jumped on an empty bus that was waiting nearby.
