I would like to have been concerned about this existential threat sooner.

I would like my architecture to inspire people to use their own resources, to move into the future.

Homegoing spans about 250 years of Ghanaian and American history. Some of this history I knew a bit about, but the novel did require an extensive amount of research, which was by far the most difficult part in the process of writing.

I knew what I had done wrong. I had followed the experts and put the money I had in television. The second time around I spent almost no money on television. The only money I spent on television, I spent on Ted Turner's station, late at night on something called Creature Feature and wrestling. Because those were things that I knew people looked at. But we spent most of our money organizing people door-to-door.

I would say there are many challenges, and that's kind of what's hard about it. And my particular thesis, since leaving Google and doing my own company, is that building a quantum computer is a little bit harder than the scientists think about because of the system engineering. Building a powerful computer is hard. So what we're particularly working on is the manufacturing of qubits and doing that much better than what people are doing right now. I really enjoyed being in academia, and even at Google working on that. But I really enjoy right now trying to think very practically about what we have to do to get this to work. And what kind of people we have to collaborate with in order to put all the pieces together and build a quantum computer in a cost effective, economic way that makes business sense.
