I love podcasts but nowadays every interview with a CEO (or anybody in power) outside of politics is often so softball. Not only in podcasts with one host but also in interviews with serious media. It is just marketing via interview.
Journalists should interview CEOs and other people in power like politicians. Do research, prepare tough questions, make them answer them, held them accountable. Some CEOs have much higher impact on our life that many politicians and we just let them spill their markting.
