Podcasts are not a good format for consuming serious information, at least in my experience. Neither are audiobooks. The problem with podcasts is they are light on real content and if it's on a technical topic and the format is having a guest be interviewed on it, the quality of information depends on the quality of questions and most people are not good at coming up interesting questions on unfamiliar topics on the spot. So you get very superficial questions and equally superficial answers. But podcasts are great for entertainment and zoning out. And for lonely people it's great to hear people talking. Darknet diaries is a good one though I don't listen consistently
