Davidson: Capturing customer attention in legacy industries is a primary hurdle

Davidson: Pessimism stems from helplessness and is solved by realizing agency
“I think a lot of pessimism tends to come from helplessness, right? It's this feeling of, well, I can't do anything about this and it sucks. Whereas actually when you realize that, no, you can, that is when you start feeling optimistic and you feel empowered.”
