Dreams
I had a very encouraging dream about nanotechnology. It was basically about being in a space colony which looked like Smith College on the outside and like Trader Joe's on the inside. There were various buildings, each run by a benevolent Emperor who had a certain color associated with him (like ancient China?) -- the building I was in was the domain of the Purple Emperor, who gave people all kinds of food and technology and explained various technical things to me. Because nanotechnology had been so far developed, everyone's physical needs were met, but there were still very interesting challenges remaining (which I don't remember).
The people who lived in the building run by the Purple Emperor slept in the aisles of what looked like a supermarket (Trader Joe's, as I said), and then the Purple Emperor periodically used nanotechnology to provide them with things they needed.
The Emperor told me that most people there didn't understand the technology involved, which was a disappointment to me.
