In the second part of my two-part interview with Bill McKibben, we spent a lot of time talking about Elon Musk, Tesla, and social trust. That included getting into the topic of unions, the UAW itself, cryptocurrency, and whether or not people with nefarious — or at least selfish and greedy — motives have intentionally split the "climate solutions community." This is surely a topic I will come back to repeatedly, and I'm almost considering writing a book on it, but it was good to get into it a bit with someone as notable, influential, and intelligent as Bill McKibben.
