I always loved the way music made me feel. I did sports at school and all, but when I got home, it was just music. Everybody in my neighborhood loved music. I could jump the back fence and be in the park where there were ghetto blasters everywhere. ↗
After realizing that we would eventually be able to build molecular machines that could arrange atoms to form virtually any pattern that we wanted, I saw that an awful lot of consequences followed from that. ↗
On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds. ↗
You can find academic and industrial groups doing some relevant work, but there isn't a focus on building complex molecular systems. In that respect, Japan is first, Europe is second, and we're third. ↗
