 One thing I wanted to ask you, the way the book starts, you have two quotes, but you say, this is from Stuart Brand, we are as gods and might as well get good at it. What's the message there? It feels pretty powerful. For millennia, our ancestors imagined these all-powerful gods. They could create new stuff. They could recast life. They could grant people's wishes to live extra life. They could transform the world around them.
