I dream of owning two homes: one on the central coast of California somewhere between Santa Cruz and Santa Barbara, and one in Japan, ideally in either one of the western districts of Tokyo (like the Meguro or Setagaya wards) or in the Kanagawa Prefecture. As a US citizen my primary residence would be in California, but I’d go to Japan regularly. For contrast, I love the California Central Coast for its tranquility and its relative lack of drama, but at the same time I love Tokyo’s vitality and sheer convenience. I’d like to be able to work as a computer scientist doing research based on my interests. I’d also like to be able to work on open source projects. I also want to occasionally teach part-time at a university, teaching courses in programming languages, AI, and operating systems. I’d like to do these things in such a way where there are no “publish-or-perish” pressures. Right now I’m figuring out how to make this happen before I get too old to enjoy it; I’m in my early 30s.
